Combination Plane

identity

• name: Combination Plane — most commonly the Stanley No. 45 and its larger, more complex sibling the No. 55; also marketed in period Stanley catalogs as the "Stanley Patent Universal Plane" [R7]. Modern equivalent: the Veritas Combination Plane [R14]. Earlier/competing names in the historical record: "Miller's Patent Adjustable Plow Plane" (Stanley's own 1870 ancestor line, models No. 41–44) [R5]; "Siegley Combination Plane" (an independent competitor's 1879 patent) [R6].
• family / category: Planing tools → the joinery-grooving branch, the multi-cutter member. Shares the fence/arm/depth-stop mechanism this corpus has already documented in the Plow Plane and Rabbet Plane entries, but instead of one stock ground for one profile, it accepts dozens of interchangeable cutter irons (grooving, beading, fluting, reeding, rabbeting, dado, tonguing/matching, slitting) via a three-part body (main stock, sliding section, fence) [R1][R2].
• one-line: A hand plane with a fence, a depth stop, and a large interchangeable cutter set, built to perform the jobs of many single-purpose joinery and moulding planes from one adjustable tool [R7][R1].
• not to be confused with: the Plow Plane (a groove-cutting plane on the same fence/arm/depth-stop skeleton, usually with a simpler cutter and support system and often a set of interchangeable straight irons; the combination plane extends that adjustable platform to a broader set of joinery and decorative profiles. Already fully documented in this corpus, including a dated Stanley No. 45–54 production table) [cross-ref]; the Rabbet Plane (cuts a corner step, not a middle-of-field channel) [cross-ref]; the Moulding Plane (a dedicated wooden plane ground once to one fixed profile, with a continuous shaped sole for full-length support — the combination plane's cutters, by contrast, are "literally suspended in midair" with no continuous sole (shorthand for the open support geometry: the cutter is clamped at the bed and supported by skates, a sliding section, a guide or an auxiliary bottom, depending on setup), a structurally harder registration problem the Moulding Plane entry's own sibling research already flagged from its own side) [cross-ref, R11]; the modern router table, a later powered substitute for many of the same operations (functional overlap, not direct lineage) [R12].

✦ how NOT to use it

• not-for (jobs it should never do):
  • not a substitute for a dedicated Plow Plane or Rabbet Plane's single-purpose ease [cross-ref].
  • not a substitute for a true Moulding Plane's pitch-matched, continuous-sole cutting geometry [cross-ref].
  • not a rounding-over tool — see matching, the Koepke/Foster correction [R18].
  • not the right tool for production-quantity work — see matching, "does not make redundant" [R12].
• dangerous (misuse that injures the user) — rebuilt in the fix pass from the mechanism, not from incident reports. A search that located no named injury account (see human side) does not show the hazards are absent. The mechanisms are foreseeable: exposed sharp cutters and scoring spurs, parts that must be clamped securely, a cutting action that can bind or dig in, and metalworking hazards if a cutter is made. The Veritas manual itself cautions that its blade is sharp and careless handling can cause serious injury [manual, relayed — the review, via a manufacturer-manual mirror; not read in this pass]. OSHA's hand-tool overview makes the general point that simple hand tools can cause severe injury when improperly used or maintained; it gives no combination-plane incident evidence [R32, relayed]. Controls:
  • Read the manual for the exact model first. Vintage No. 45, No. 55, Record and modern Veritas setups are not interchangeable. Inventory all required parts against the manual and parts diagram, and treat an unverified or incomplete vintage setup as non-operational until matched. Do not improvise a missing runner, blade clamp, depth stop, fence part or fastener.
  • Inspect before use: body castings for cracks, rods for bends, threads for stripping, clamps for secure engagement, and the fence, depth stops, skates, cutters and nickers for cracks, corrosion, incorrect grinding or loss of profile. Vintage bodies can be cracked, bent, incomplete or insecure (see damaging).
  • Workholding: secure the workpiece against forward and lateral movement. Narrow work can shift, so use adequate workpiece width and support, support long, narrow or thin stock, keep the plane's travel path clear, and keep a balanced stance.
  • Hand position and edge handling: handle, install, hone, deploy and store cutters, nickers and scoring spurs as exposed sharp edges. Keep fingers off the edge and never test sharpness by sliding a finger along it. Keep the off hand behind and clear of the cutter and spurs. Store cutters so their edges cannot be contacted or damaged, and cover or remove exposed cutters before transporting or storing the plane.
  • Cutting: set a fine cut, verify fence and depth-stop lockup, and test on scrap. A deep or poorly supported cutter can dig in abruptly. Stop immediately if a cutter shifts, chatters, binds or digs in, if the cut widens unexpectedly, or if the fence drifts. Use the support configuration prescribed for the cutter, use a backer for cross-grain work where the exact procedure calls for it, and deploy and align scoring spurs only as the manual specifies. Do not over-tighten vintage screws or repeatedly compensate for creep; repair or replace a defective clamping component.
  • Slitting is its own configuration: a slitting cutter is a knife operation that separates a strip. It needs its own workholding, hand clearance, grain, thickness and separated-strip control, not a parenthetical "without a saw."
  • Custom cutters: profiling and heat treatment are separate hazardous processes. Grinder work needs eye and hand protection and clear fire control. Heat treatment with a torch or furnace, hot steel and quench oil carries burn, fire, fume and eye hazards, so it needs ventilation, fire control and PPE. As-quenched tool steel can be stressed and brittle; use a known alloy and its full schedule including tempering, or a professional service, and check the finished cutter for cracks and straightness before use.
• damaging (misuse that ruins the tool or the work):
  • blade creep under load — a real, first-person, named-forum account with a diagnosed mechanism: Denis364 (Fine Woodworking, 2002), "the blade has a tendency to creep forward, so it's important to tighten the adjustment screws after each pass. This keeps the plane from digging in" — one poster's reported habit on his own plane, not a class-wide instruction. Re-tightening every screw after every pass can strip threads, distort settings or conceal a worn or defective clamp that should be repaired; if a blade creeps, stop and diagnose it rather than normalizing it (the caution is from the review) [R17, attributed practitioner evidence — directly quoted, named poster].
  • cutter/spur misalignment causing chatter and tear-out — a named 40-year user's direct diagnosis: Warren Mickley (Sawmill Creek), "It sounds as if there is no clearance between the nickers and the blade... the nickers have to extend down more than the blade also." Steven C. Newman, same thread: "If the spurs are out too far, leaving the edges of the cutter unsupported, the cutter will chatter and tear-out... Cutter's edges should be flush with the outside edges of the skates" These are named practitioners' diagnoses. Cutter-edge alignment, skate alignment and spur projection are separate dimensions, and the procedure is the maker's: for the current Veritas dado setup, spurs start flush with the skates and are then projected only a few thousandths of an inch beyond them, confirmed with test cuts [R24] [R18, attributed practitioner evidence — full thread read, named posters]..
  • the cam-stop's original thumbscrew breaking — a real, dated, Stanley-acknowledged design defect: the first-type cam depth stop (added 1901) used a thumbscrew "with a tendency to break," redesigned during the production run itself to a stronger solid iron piece — direct evidence the fragility was a known, addressed manufacturing defect rather than only later collector-era damage [R8, HIGH — museum-curatorial text, cross-corroborated].
  • bent fence rods and cracked fence castings — real, specific, repeated failure points reported in restoration/collector listings: threaded rods "bent right where the threads start," and the fence casting's own curved neck "cracks" under stress [R9, MEDIUM — search-synthesis of multiple restoration-thread/listing sources, not independently fetched to HIGH this run].
  • (honest gap, not papered over: no direct account of a cutter itself snapping or chipping in use was found despite a targeted search — the "many odd-shaped irons are inherently less supported than one thick bench-plane iron" mechanical reasoning remains plausible but unconfirmed by a real breakage account this run.)
• beginner-trap (mistakes that look fine until they aren't) — the corpus's strongest-sourced beginner-trap class to date. See human side above for the full Pirnik/Woodentop/berferdt No. 55 material, the Stew Denning 50-year-unused No. 45, and the mixed current-tool evidence (the Veritas plane still needs setup and practice but is reported as easier than vintage examples). In short: buyers repeatedly report assembling and tuning the plane by every visible measure, then abandoning it after the cutter still dug in or chattered. One commenter's reported technique (a stroke direction and pass sequence on his own No. 55 setup, not general instruction) suggests the working method is not obvious and was not consistently documented in period instructions [R11, attributed practitioner evidence].
• lineage-misuse (treating it like a related-but-different tool):
  • expecting factory-tool ease from a multi-function tool — the sibling Plow Plane entry's own sourced verdict (Weaver): "A 45 works fairly well as a plow plane. Not that great for anything else" [cross-ref, R16].
  • expecting it to match a dedicated single-purpose plane's precision — Larry Williams's direct rejection of the "only game in town" framing, and Troy McDonald's direct comparative finding against the Veritas plane's own dedicated companion tools [R10, attributed practitioner evidence][R12, HIGH].
  • expecting it to perform like a true Moulding Plane — the sibling entry's own citation of this tool as a "related but genuinely different" descendant is independently confirmed and sharpened here: a combination plane's cutters have no continuous sole to reference against, unlike a dedicated moulding plane — "literally suspended in midair," per Mario Rodriguez's own direct technical description [R11, attributed practitioner evidence].
  • expecting the beading cutters to round over an edge — the Koepke/Foster correction above [R18].

correct use

Brief — the workbench holds deep operation. In one sentence: the combination plane performs many of the plow plane's, rabbet plane's, and simple moulding plane's jobs from one tool, at a real, well-documented cost in setup time and learning curve compared to any one of those tools used alone.

• what it's genuinely good at: reproducing or matching a short run of an existing moulding profile (the single most-repeated real use case across every source consulted) [R11][R12]; one-off grooving, rabbeting, or beading jobs where setting up a router table doesn't pencil out for the quantity of work [R12]; custom-ground cutters for a profile no stock cutter or router bit fits [R11].
• how to use it well (brief): read the manual for the exact model before assembly or use — a directly-sourced piece of advice from a named reviewer of the CURRENT tool [R12, HIGH]; use the maker's setup and tightening sequence, tighten clamps securely to their designed condition before the cut, then stop and diagnose any movement rather than normalizing blade creep (one forum poster's re-tighten-after-every-pass habit is a report, not a rule: repeated forcing can strip threads or hide a worn clamp) [R17, attributed practitioner evidence]; use the support configuration the manual prescribes for the cutter (narrow blade with its guide, wide blade with sliding-section support, irregular profile with the auxiliary center bottom) [manual, relayed][R11]; choose travel direction from grain, blade handedness, fence position and profile, and treat any fixed left/right rule as one user's technique; one forum account says anything but straight grain on the No. 55 is "a nightmare" [R17, attributed practitioner evidence]; set a fine cut and test on scrap.

✦ matching

The workbench's first read.

• does: "cuts a groove of a set width and depth" (plow/grooving function, ⅛"–¾" typical on the No. 45; the Veritas plane spans ⅛"–1"); "cuts a rabbet or step at an edge"; "cuts a dado across the grain" (with nickers/spurs); "cuts one half of a tongue-and-groove joint" (match function); "cuts a bead" (edge or center); "cuts reeding or fluting" (parallel raised or concave lines, with special cutters); "parts/rips thin stock to width" (slitting function); "cuts simple mouldings" (with special bottoms/cutters, more elaborate combinations on the No. 55/Veritas) [R1][R9][R14]. Lee Valley's own current copy adds a real, sourced technique extension: "with the addition of a shop-made batten, the plane can also be used to cut through-dadoes" [R14, HIGH].
• suits: drawer-bottom and case-back grooves, panel grooves, and edge beading — the same territory as the Plow Plane, but in one tool alongside beading/tongue-and-groove capability; reproducing or matching a missing or damaged moulding profile in a short run, the single most-repeated real use case — Mario Rodriguez, a named professional, directly: "Most often I call upon my 55 to run off a few feet of molding for a piece of furniture or a piece of trim missing from some architectural treasure" [R11, attributed practitioner evidence]; named forum poster Denis364, independently: "if you need 10 feet of a 1920's molding, its the only economical game in town" [R11, attributed practitioner evidence]; one-off joinery where a router table setup isn't justified for the quantity — Carl Duguay: "You'll find it a welcome alternative to the router for cutting occasional grooves and rabbet or when doing edge treatment on one-off projects" [R12, HIGH].
• kit-fit:
  • pairs with: a marking gauge for layout, as in the sibling Plow Plane entry; a Router Plane for truing a groove floor (same relationship as the plow plane, cross-ref); custom cutters for a profile no stock cutter fits. Rodriguez's worked method (trace the old profile in paint with a scratch awl at the plane's fixed 45° bed angle, rough with a hacksaw or grinder, file to shape) covers shaping only; his closing "harden by quenching" shortcut is withdrawn, because quenching alone is not a complete heat treatment [R11]. A custom cutter may be shaped from a known annealed tool-steel blank, then heat-treated to the supplier's alloy-specific schedule, including tempering, or sent to a qualified heat treater. Do not infer a quench medium or temperature from appearance. O1, for example, needs controlled preheat and austenitizing, an oil quench and prompt tempering, and is somewhat prone to quench cracking [R26, read this pass]; Veritas describes its own O1 blades as oil-quenched and double-tempered and its A2 blades as air-quenched and double-tempered [relayed from the review; the Veritas planes page fetched this pass confirmed the steels but not the schedules]. Heat treatment is a separate hazardous metalworking process, not an ordinary plane-adjustment step — see dangerous. Profiling a stock-cutter-compatible blank is also a different job from using a stock cutter.
  • substitutes for, tested against real users rather than taken on Stanley's own marketing claim: Stanley's own period language and modern retail synthesis frame it as replacing "an entire cabinet full of specialty tools" / "seven planes in one." Tested directly, the verdict is genuinely mixed, not a clean confirmation: Alan (FWW forum, 2002, positive, sustained-use account): "I use it for just about everything: from moulding edges to plowing grooves to making moulding." Danford C. Jennings ("Dano," same thread), a real comparative account after owning both: sold his No. 55 as too complicated, kept the No. 45 as "a 'snap' to set up... I wouldn't give up my #45 for any amount of money." Set against this, Larry Williams (named professional toolmaker) rejects the substitution claim outright: "They're far from the 'only game in town.' Molding planes are not only superior" [R10, attributed practitioner evidence — see human side]. Troy McDonald, a named professional reviewer of the current Veritas tool: "it could not compete with that of its companion tools such as the Veritas small plough and rebating planes" [R12, HIGH]. The entry does not resolve this to a single verdict — it depends on how much setup time and learning-curve cost the user is willing to spend (see access).
  • does not make redundant (a trade-off, not an absolute: a well-set combination plane can do these jobs; the question is setup time, control, finish and repetition): a dedicated Plow Plane or Rabbet Plane's ease and precision for its single job — the sibling entry's own sourced access debate (Weaver/Dorn/Drew) already states this from the plow-plane side [cross-ref]; a true dedicated Moulding Plane's pitch-matched cutting geometry, comfort, and continuous shaped sole — Williams again, directly: "they come in different pitches to match the wood being used, they're comfortable to use and a lot more versatile" [R10, attributed practitioner evidence]; a router/router table's speed for production-quantity work — Duguay: "For production runs you'll still likely want to revert to the 'scream machine'" [R12, HIGH].
• not-for (project-keyed):
  • don't reach for it as a first hand plane — see access.
  • don't use the standard beading cutter set expecting to round over an edge — a real, corrected beginner misconception, directly analogous to the Moulding Plane entry's own beginner-trap finding: named Sawmill Creek poster Jim Koepke, "Putting rounds on edges is not one of its stated uses"; the thread's own original poster independently confirms after reading the manual: "I just downloaded the manual for the #45 and realized it could not be used for rounds" [R18, attributed practitioner evidence].
  • don't expect factory-tool ease of setup — real setup and tuning time is a documented, repeated cost, not an occasional complaint (see access).
  • don't push it through figured or reversing grain without a real fallback technique — the open, unsupported cutter geometry (no continuous sole) makes tear-out worse here than on a true moulding plane [R12].
  • don't reach for it for high-volume production work — see kit-fit, "does not make redundant" [R12].
• access: a well-documented learning curve, corroborated far beyond the sibling Plow Plane entry's own sourcing and strongest for vintage No. 45/55 examples, with mixed evidence on the modern Veritas tool: it still demands configuration-specific setup and practice, but reviewers generally find it easier and more secure than vintage examples (Pavlak: "far easier to use than those old combination planes" [R25]). Named Sawmill Creek posters (2014 thread, read in full): Jim Koepke, "The Stanley #45 has a learning curve that is difficult for some. For me it works well, but it requires paying close attention with every stroke"; Bob Glenn (owns both a 45 and 55), "you must pay attention to each stroke... or the plow will deviate from the groove." Scott C. Frankland (FWW forum, 2002), directly confirming the sharpening-difficulty hypothesis as a real, named complaint rather than speculation: "setting the blade is a little harder than a normal bench plane... the blades can be a real job to sharpen and you can easily screw them up if you are not careful." On the No. 55 specifically, Denis364: "There is a stiff learning curve to using the 55. Anything but straight grain is a nightmare." On the CURRENT Veritas plane, Carl Duguay (senior editor, Canadian Woodworking, 2026-updated review) and Troy McDonald (Australian Wood Review, 2018) report different things: Duguay advises reading the manual and practicing and calls it a useful one-off alternative; McDonald reports setup fussiness and one off-square reeding cutter on his review unit (one QC observation, not a class property) while noting occasional users may find the setup time minimal [R12][R25]. The forum quotes above are attributed practitioner evidence [R17][R18].
• revival: Troy McDonald's own buyer-segmentation finding, the clearest sourced "who should actually buy this" account found: "For hand tool enthusiasts that regularly need to perform joinery tasks I anticipate the inevitable set-up time... will be enough to justify the purchase of dedicated planes... For those that can't justify the cost of individual tools or those that desire the occasional use of a hand plane like this, the versatility of the plane will far outweigh the minimal set-up time" [R12, HIGH]. The strongest concrete revival case is restoration/matching work — reproducing a short run of a discontinued or damaged moulding profile where no dedicated plane or router bit exists and a custom-ground cutter is the only economical option [R11].

anatomy

• the body / main stock — the primary registration surface, holds the cutter's main support skate [R9][R11].
• the sliding section — a second body section, clamped to the same rods as the fence, adding a second skate for cutter support; per a named professional's instruction for wide or complex cutters on vintage-style setups: "The cutter should be supported by at least two skates, one from the main body and the other from the sliding section. If the cutter is wide or the profile complex, the auxiliary center skate should be used as well" [R11 — Mario Rodriguez, Fine Woodworking contributing editor, full text read; attributed practitioner evidence for one configuration]. Support is configuration-specific, not universal. Per the reviewer's reading of the Veritas manual, for narrow blades the sliding section is removed and a small blade-guide knob supports and aligns the blade [manual, relayed]; Lee Valley's page says the sliding section "supports the outer edge of the blade" [R14]. In short: narrow straight blade with its prescribed guide; wide blade with sliding-section support; irregular profile with the auxiliary center bottom or specified third support. Use the manual for the exact plane and cutter..
• the fence — registers off the board's edge, as in the sibling Plow Plane entry's own anatomy block; on the No. 55, right- and left-hand adjustable rosewood fences are fitted rather than one, ordinarily set parallel to the cutter (a 45-degree two-fence arrangement is one specialized chamfer setup shown in the manual) [manual, relayed][R3]; the modern Veritas plane has a single REVERSIBLE fence that goes on either side to suit handedness and grain direction [R14]. Some left-hand-only blades (1/8" to 3/8") cannot be used on the Veritas plane because of the blade adjuster's position; the reversible fence lets right-hand blades cut in both directions [R14].
• the arms / rods — short and long rod pairs joining fence, sliding section, and body; on the modern Veritas plane, two rod-pair lengths ship standard [R14, HIGH — manufacturer copy, fetched live].
• the depth stop(s) — the No. 45/55 shipped two depth stops for the sliding section, one short and one longer ("the heading gauge") [R11, attributed practitioner evidence]. A cam-style depth stop was added in 1901; its first version used a thumbscrew "with a tendency to break," redesigned by Stanley to a stronger solid iron piece with a slotted screw — a real, dated, Stanley-acknowledged design fix during the production run itself [R8, HIGH — museum-curatorial text, cross-corroborated].
• the auxiliary center bottom — a third point of support for an irregular-profile cutter (e.g. an ogee, where one side of the cutting edge extends below the other), used alongside the main-body and sliding-section skates [R9, MEDIUM — period-manual search-synthesis, not independently fetched to HIGH this run].
• the cutters/irons — narrow, interchangeable, ground to specific profiles: groove/plow, rabbet, dado, match (tongue-and-groove), edge and center bead, slit, sash, plus separately-purchased special bottoms/cutters for simple mouldings, nosing, reeding, and fluting. Named cutter-number ranges found in collector sources: beading cutters #21–29, reeding cutters (212/222/232), fluting cutters (32/34/36/38) [R9, MEDIUM — search-synthesis, not independently verified against a fetched primary catalog].
• spurs / nickers — scoring spurs ahead of the iron for cross-grain work. Cutter-edge alignment, skate alignment and spur projection are separate adjustments. For the Veritas dado setup, Lee Valley says to begin with the spurs flush with the skates, then deploy them only a few thousandths of an inch beyond the skates, confirm with test cuts, and use a backer at the far edge of a cross-grain dado [R24, read this pass]. Use the exact model's alignment and projection procedure. A spur too far out can widen or rag the cut; too little projection may not sever cross-grain fibers before the main blade. Spurs are exposed sharp edges — see dangerous.
• the slitting cutter — a commonly-missing component in surviving sets; a knife operation that parts thin stock to width and produces a separated strip. It needs its own workholding, hand clearance, grain and thickness control — see dangerous [R9, MEDIUM].
• Veritas Combination Plane (current production) — anatomy independently confirmed against live manufacturer copy: two-part body (main body + separate sliding section), 10½" long, 4 lb, stress-relieved ductile iron, brass fittings, torrefied maple tote; adjustable scoring spurs on BOTH body and sliding section; threaded/micro-adjust depth stops on both sections plus a micro-adjust thumbscrew for the fence face; a 45° blade bed matching the No. 45/55; accepts Veritas, Record 405, AND original Stanley 45/55 blades directly (the current Veritas plane is a redesign, not an instruction-equivalent reproduction: its narrow-blade guide, reversible fence and micro-adjustments differ from vintage setup) — a genuine backward-compatibility claim [R14, HIGH — manufacturer's own current copy, fetched in full].

Honest gap, inherited from the sibling Plow Plane entry: Patrick's Blood & Gore's dedicated Stanley 45/55 anatomy pages (supertool.com/StanleyBG/) remain JS-gated and could not be fetched — a standing blocker on this domain across four entries in this corner of the corpus now. The original Stanley No. 55 instruction manual (found on archive.org via search, not fetched this run) would resolve the auxiliary-center-bottom and slitting/sash-cutter detail to HIGH in a future pass.

variations (living)

• Miller's Patent line (Stanley No. 41–44, 1870–1890s) — the direct Stanley-internal ancestor: plow, filletster, and matching-plane functions with metal screw threads instead of wood [R5].
• Siegley Combination Plane (independent, 1879–1905, absorbed into Stanley) — a competing lineage, not a Stanley design, running in parallel for over two decades before acquisition [R6].
• Stanley No. 45 (1884–1962) — the anchor entry of this family, 18–23 cutters across its run [R1][R9].
• Stanley No. 55 "Universal Plane" (1897–1963 (Stanley support page, relayed)) — larger, two-fenced, 52–55+ cutters, the more complex and more criticized sibling [R3][R4][R11].
• 1984 Paragon Multi-Plane — a direct Sheffield-made reproduction commissioned by Garrett-Wade and Lee Valley, predating the Veritas plane by decades as "someone tried to bring it back" [R15, MEDIUM].
• Veritas Combination Plane (current) — precision-machined modern redesign, reversible single fence, backward-compatible with original Stanley/Record blades; listed by Lee Valley at US$495 when checked 2026-10-16 (also US$495 at the reviewer's 2026-08-01 check) — a dated market observation, not an identity fact [R14, HIGH for the product description].

trades (where it appears, with trade-specific notes)

• woodworking / joinery / cabinetmaking (essentially the only trade found). General furniture and case joinery (drawer/case-work grooves and beads in one tool); architectural trim and restoration work matching an existing profile — the single most-cited real application across every source consulted [R11][R12]. No carriage-making, timber-framing, or metalworking crossover was found this run, unlike the sibling Rabbet Plane entry's own carriage-building citation for a related tool — an honest, actively-searched gap, consistent with the pattern the Plow Plane and Moulding Plane sibling entries each report for themselves.

lineage

• ancestors:
  • Miller's Patent Adjustable Plow Plane — a real, Stanley-internal ancestor 14 years before the No. 45, not previously documented anywhere in this corpus. US Patent 104,753, Charles G. Miller, issued June 28, 1870. Stanley purchased the patent and hired Miller himself (b. Brattleboro, VT, 1826; relocated to New Britain, CT for the deal; left Stanley in 1876). Miller's design combined plow, filletster (rabbet), and matching-plane functions with metal screw threads replacing wood, marketed as the "Millers Patent" line (Stanley models No. 41–44, 1870, phased out by the 1890s) [R5, HIGH — Early American Industries Association article, read in full, citing named collector Don Bosse's ongoing primary research]. Independently corroborated by Gregory Schipa's 1983 Fine Woodworking retrospective: "In 1871... Stanley introduced the 'Miller Combination Plane' as a replacement for the carpenters' plow... Within a few years Stanley came out with the #45, which replaced a boxful of plows, fillisters and beaders" [R2, HIGH — full article read]. Miller separately patented two dedicated match (tongue-and-groove) planes — US 142,307 (1873, cast iron, never manufactured, only 2 known survivors) and US 165,355 (1875, went into production as the Stanley No. 48/49 Tongue and Groove Plane, 1877–1942) — plus a third, more elaborate match-plane version (US 181,357, 1876) built by Stanley's own Model Shop but never put into production, one surviving numbered prototype (#537) documented and photographed [R5, HIGH].
  • A genuine, independent, competing inventor — Jacob Siegley, predating Stanley's own No. 45 base patent by nearly five years. US Patent 216,979, "Improvement in Bench-Planes" ("Siegley Combination Plane"), Jacob Siegley, New York NY, applied Dec. 6, 1878, granted July 1, 1879 — DATAMP's own record states plainly: "This is the first of Siegley's patents on a combination plane." Claims a moveable front skate, interchangeable cutters, and a cutter clamp [R6, HIGH for the date/priority claim — direct DATAMP record. The reviewer's 2026-08-01 review reports the patent text verified on Google Patents (granted July 1, 1879; a combination bench-plane with interchangeable plow, bead, scratch-bead, dado and rabbet attachments) — relayed, not read in this pass]. Siegley followed with two improvement patents (US 245,752, 1881; US 269,968, "designed with a view to lock the cutting-tool or plow in a more reliable manner," 1883) [R6]. Stanley eventually acquired the competitor's business (an acquisition does not show Stanley failed to innovate; the patent record shows parallel and iterative development): Siegley made planes independently in Wilkes-Barre, PA from ~1884, signed a deal to produce transitional planes for Stanley in 1901, and sold his entire business to Stanley in 1905 — Stanley continued marketing planes under the Siegley name until roughly 1927 [R6, HIGH — DATAMP record citing John F. Rumpf's Plane Makers of Wilkes-Barre, Pennsylvania].
  • The Rabbet Plane and Plow Plane's own shared fence/arm/depth-stop skeleton is the direct mechanical foundation this tool expands, not a separate lineage — see those sibling entries for the deeper Moxon-era (1678–83) roots of the mechanism itself [cross-ref].
  • A crowded field, not a clean single line. A search-synthesis source names further period competitors — Fales, Walker (Edwin Walker's US 318,331 "Adjustable-Faced Plane," 1885, already cross-referenced in the sibling Plow Plane entry as "among the most complex of all patented planes ever produced," is contemporaneous with, not derivative of, the No. 45) — and calls Justus Traut's 1895 patent with Edmund Schade a precursor to the No. 45 [R13, MEDIUM — search-synthesis blog; that precursor framing is withdrawn]. Resolved in this fix pass: the patent is US 532,842, applied for June 20, 1894 and granted January 22, 1895, the patent branch that became the Stanley No. 55 (on sale 1897), not a precursor to the already-existing No. 45. Per the review it calls itself an improvement on Traut's 1884 patent and McCulloch's 1893 patent [patent self-description relayed from the reviewer; number, dates and No. 55 link read in the EAIA account, R22, R23]. The sequence: Traut's 1884 No. 45 patent; McCulloch's 1893 auxiliary-stock patent; Traut and Schade's 1895 improvement; Stanley No. 55 introduced 1897.
• descendants / living variants:
  • The Stanley No. 55 (1897) — the No. 45's larger, two-fenced sibling; see history below.
  • The Veritas Combination Plane (current production) — a modern, precision-machined redesign that explicitly accepts original Record 405 and Stanley 45/55 blades, a genuine backward-compatibility claim [R14].
  • The 1984 Paragon Multi-Plane — a direct reproduction of the No. 45/55 form, commissioned by Garrett-Wade (USA) and Lee Valley (Canada), made in Sheffield, England, dated by its own instruction booklet to November 1984 [R15, MEDIUM — single named first-person forum account, not independently verified against a manufacturer catalog record].
• contemporaries — related but genuinely different tools:
  • The Plow Plane — a groove-specific plane on the same fence/arm/depth-stop mechanism, usually with a simpler cutter/support system and often interchangeable straight irons; the sibling entry's own sourced access debate (Weaver/Dorn/Drew) already frames the trade-off directly from the plow-plane side: "There are better tools for any of the jobs [the combination plane] will do" [cross-ref, R16].
  • The Moulding Plane — a dedicated wooden plane with a continuous shaped sole; this entry's own research (see matching) independently confirms and sharpens that sibling entry's own finding of the combination plane as a related-but-inferior descendant for pure moulding work, because the combination plane's cutters have no continuous sole to reference against — "literally suspended in midair," per a named professional's direct description [R11, attributed practitioner evidence].
  • The modern router / router table — a later powered substitute for many of the same jobs (functional overlap, not direct lineage), with a real, sourced trade-off: faster for production runs, but unable to match a custom-ground cutter for an obsolete or one-off profile [R12].

history

• The base Stanley No. 45 patent — this entry's first organizing finding: a sibling entry's own honest gap, resolved. The Plow Plane entry (Run 332) attempted a direct DATAMP fetch of designer Justus A. Traut's own patent cross-reference list and confirmed his chronology through Feb. 19, 1884, but could not locate the specific number for the widely-cited "March 11, 1884" base patent. This run found it directly: US Patent 294,825, "Bench-Plane," Justus A. Traut, New Britain, CT, assigned to Stanley Rule & Level Co. — applied Oct. 17, 1883, granted March 11, 1884 — read in full on Google Patents. The patent's own claim text states directly: "My invention relates to improvements in bench-planes. In my improved plane I combine a beading and center-beading tool, plow, dado, fillister and rabbet, matching-tool, and slitting-tool." It references a prior patent to himself dated March 4, 1873 (the earlier draft of this entry gave March 1, which was wrong; the predecessor is US 136,469, Traut, granted March 4, 1873, a tool combining plow, dado and rabbet functions, confirmed on Google Patents in this pass, R21) as the tool's own mechanical ancestor, and cites Rappleye's patent No. 266,519 (1882) for the slitting-knife mechanism it incorporates — directly explaining, in the inventor's own words, why the new design could take a cutter as narrow as 1/8 inch where its 1873 ancestor could not (steel blades let into the stock, replacing solid cast iron) [R1, HIGH — read in full, primary source]. Context only: Traut also held US 291,815 ("Bench-Plane," filed Nov. 23, 1883, granted Jan. 8, 1884, a convertible bull-nose/block-plane mechanism), which shows his broader patent activity in the window. It is not combination-plane proof, and no mechanical lineage to the No. 45 is claimed [R1].
• The No. 45's production run: 1884–1962, roughly 78 years, cross-corroborated across three independent named sources [R2][R3][R9]. Cutter count expanded over the run: 18 cutters (1883–1896), 20 (1896–1909), 21 (1910–1920), 22 (1921), 23 (1922 onward) [R9, MEDIUM — collector-site cross-corroboration, not independently verified against a fetched primary catalog].
• The No. 55 — introduced 1897, corroborated independently across three named sources (Schipa 1983; workingbyhand.wordpress.com 2018; Pirnik 2014, all read in full), production dated 1897–1963 on Stanley's own support page [relayed from the review, not read in this pass]. Marketed with right- and left-hand adjustable rosewood fences instead of the No. 45's one [R3]. Per the reviewer's reading of the original Stanley No. 55 manual [manual, relayed], the fence faces ordinarily guide the plane along the work and are set parallel to the cutter, with both fences advisable where possible; the rosewood faces can be rotated for angle work and arranged as bottom supports for particular chamfers. The earlier draft's account of the two fences bisecting a 90° corner at 45° each described one specialized moulded-chamfer arrangement, not the normal configuration, and is withdrawn as a general description. Introduced with 52 cutters, later expanded to 55 (plus 40+ specialty cutters orderable); full kit weight cited at 15¼ lb in the 1914 catalog [R3, MEDIUM-HIGH, single named source].
• "The most complex hand plane ever made" — correctly attributed to the No. 55, not the No. 45, a correction the sibling Plow Plane entry already made from its own side. This run traced the most vivid version of the claim to a real, named, credentialed source: Patrick Leach ("Patrick's Blood & Gore," supertool.com, the canonical Stanley-plane collector reference already cited HIGH by two sibling entries): "Bought it. Used it. Hated it. Sold it," and, more vividly, that suffering the No. 55's use would be preferable to being "chained to a rock and [having one's] liver eaten daily by an organ-hungry raptor." The supertool.com page itself is JS/session-gated and could not be fetched directly this run — the same standing blocker three sibling entries report on this domain — but the attribution is cross-corroborated by an independent named Fine Woodworking commenter ("chuckh," 2015) who separately quotes and correctly attributes the same line [R4, MEDIUM-HIGH — attribution confirmed via two independent citations, not read on the primary page itself].
• Stanley's own period marketing — directly quoted, from two independent named sources citing the 1897/1898 catalogs. Gregory Schipa, Fine Woodworking #38 (1983), read in full: "As the Stanley Tool Company modestly described it in their 1897 catalog: Combining as it does all the so-called 'Fancy' Planes, its scope of work is practically unlimited, making the Stanley #55 literally 'A planing mill within itself.'" Independently corroborated by workingbyhand.wordpress.com (2018, read in full), which separately quotes the 1898 catalog's own trade name — "Stanley Patent Universal Plane" — and a fuller functional claim listing five categories: moulding plane; match/sash/beading/reeding/fluting/hollow/round/plow/rabbet/filletster plane; dado plane; slitting plane; chamfer plane [R7, HIGH for the existence and substance of the claim — two independent named sources with overlapping but non-identical wording, consistent with each drawing on the real catalog rather than each other; MEDIUM for word-for-word exactness, since neither source is the catalog scan itself]. For the No. 45 specifically, the "replaces a boxful of plows, fillisters and beaders" framing is Schipa's own 1983 characterization, not a directly quoted 1884-era catalog line — a targeted search for a period-specific No. 45 marketing quote analogous to the No. 55's found nothing; reported as an honest gap rather than papered over with the modern "Seven Planes in One" tagline (real and repeated across collector/retail sites, but not independently dated to the original 1884 launch this run) [R2, MEDIUM].
• The wooden-moulding-plane cost problem this tool was built to solve, per a named author's own framing: Schipa's 1983 piece states the pre-existing problem correctly — "a cabinetmaker or housewright might have needed a hundred [wooden moulding planes] to fashion all the moldings in style, an expensive and weighty collection to store and transport" [R2, HIGH]. A period (pre-1950) first-person account of a buyer choosing the combination plane specifically to avoid that cost was searched for directly and not found this run — an honest gap. The closest evidence is modern-market, not contemporary: on today's used market, a Stanley No. 45 body with a single iron can sell for less than a single dedicated plow plane [R17, attributed practitioner evidence — forum-sourced, modern market only].

✦ human side

• ★ The strongest, most extensively corroborated beginner-trap human-side material found for any tool in this corpus to date — read in full, both a named professional article and its 21-comment thread. Ed Pirnik, a named Fine Woodworking editor, "The Weirdest Handplane I've Ever Used" (2014): bought a complete boxed No. 55 (all 55 irons) for $20 at an antique shop — itself evidence of how commonly these sit unused and undervalued. His own technical description of why: "it doesn't really have a sole on the bottom — the bearing surfaces are the narrow edges of the 'skates' and the rosewood fences." The comment thread converges independently and repeatedly on the same pattern. Named commenter "Woodentop": "Most of these sat in boxes unused because they were advertised as a panacea... After selecting the cutters and honing the irons and carefully setting all the skates depth stops and nickers the user then tried working right to left with the lightest touch because the damned contraption would dig in and jam then [they] got put away in their box" — he then describes the technique he uses: work left to right until near full depth, then finish right to left. That is one commenter's technique on one No. 55 setup, not general instruction; travel direction depends on fence side, handed blade, grain direction, work orientation, cutter profile and model. Named commenter "berferdt," independently: "The 45 and 55 both had the same problem regulating the cut. Too often the new owner had no idea why it didn't work as advertised, so it went back in the box. A treasure for tool junkies, a bane for tool users." Pirnik's own closing observation, after moderating the thread: "it seems that these tools are often in great shape because nobody ever took the time to really master the tool" [R11 — attributed practitioner evidence (named article author and named commenters), full article and thread read; naming a poster improves attribution, not external verification].
• A named professional toolmaker states the pattern plainly, and is a recurring figure across this corpus. Larry Williams (already cross-referenced in this corpus's own Moulding Plane entry), on a FineWoodworking forum (2002): "I've owned a couple Stanley 55 combination planes. They're not here anymore; I sold them. They're far from the 'only game in town.' Molding planes are not only superior; they come in different pitches to match the wood being used, they're comfortable to use and a lot more versatile. As Michael Dunbar pointed out in a FWW article a couple years ago, there's a reason so many old combination planes are found in basically un-used condition" [R10, attributed practitioner evidence — directly quoted, named professional, independently corroborates and sharpens the sibling Plow Plane entry's own inferred "abandoned in mint condition" pattern with a direct, attributed statement of it].
• A real, physically-evidenced, multi-generational inheritance account. "chuckh" (Fine Woodworking comments, 2015) inherited a No. 55 from a great-uncle "who was a very skilled craftsman and built homes when they did most of the millwork on site," and reports the physical wear pattern directly: "the fences show wear but very few of the blades show any wear. Only the grooving blades and a couple of the beads. So even he must have quickly learned the frustration and limitations of this tool" — a genuine, physically-observed account of a real period tradesman's actual usage pattern, not modern hobbyist speculation [R11, attributed practitioner evidence — first-person, physically observed, unverifiable beyond the poster's own account].
• A real, credentialed restoration-trade use account. Named Fine Woodworking commenter "Applejoe" (on the No. 55 article): "I have both a 45 and 55, use both of them to reproduce missing or damaged mouldings in my early 18th century home... you gotta-wanna do it enough to spend the time and endure a little frustration along the way" — mirrors the professional-restoration-use pattern this corpus's Rabbet Plane and Moulding Plane entries already document (Bickford's own moulding-plane-making business), for the combination plane specifically [R11, attributed practitioner evidence].
• The modern Veritas plane still demands setup and practice, but current reviews are mixed and generally find it easier and more secure than vintage examples. Carl Duguay, senior editor of Canadian Woodworking (article updated Jan. 2026, read in full): the current Veritas Combination Plane still ships "17 brass knobs, along with the posts, scoring spurs, depth stops, adjustment screws and a multitude of cutters" and "looks somewhat intimidating"; his direct advice: "you'll save yourself a lot of frustration if you actually read the manual before you begin to use the VCP" — and he calls it a useful alternative for one-off work. Troy McDonald, Australian Wood Review (2018, read in full): reports setup fussiness and that the review unit's reeding cutter arrived "profiled slightly off square" (one reported QC observation on one unit, not a class property), while noting that occasional users may find the setup time minimal relative to the versatility. Fine Woodworking's Bill Pavlak calls the Veritas version "far easier to use than those old combination planes" and rates its blade lockup "exceptional" [R25, read this pass]. Lee Valley itself says the current design holds settings securely. [R12, R25 — named, dated reviewers' opinions; HIGH is not claimed for class-wide difficulty]
• injury/damage accounts — none located in this run's search. That is a research result, not a risk assessment: the plane has exposed sharp edges and foreseeable hazards, set out in dangerous below.

✦ proof of existence

• the base No. 45 patent, resolved and read in full this run: US Patent 294,825, Justus A. Traut, applied Oct. 17, 1883, granted March 11, 1884 — closes the sibling Plow Plane entry's own honest gap #1 directly [R1, HIGH].
• the predecessor and the No. 55 branch: US Patent 136,469 (Traut, granted March 4, 1873, combining plow, dado and rabbet) confirmed on Google Patents in this pass [R21]; US Patent 532,842 (Traut and Schade, applied 1894, granted January 22, 1895), the No. 55 branch, with number and dates read in the EAIA account [R22][R23].
• the Stanley-internal ancestor patent: US Patent 104,753, Charles G. Miller, June 28, 1870, sourced to a named tool historian's article citing ongoing primary collector research [R5, HIGH].
• the independent competitor's founding patent: US Patent 216,979, Jacob Siegley, granted July 1, 1879 — DATAMP-confirmed as his first combination-plane patent, five years before Stanley's own base patent [R6, HIGH for the date/DATAMP record; full patent text reported verified on Google Patents in the review [relayed], not read in this pass].
• museum holdings: the Waikato Museum (Hamilton, New Zealand) holds an accessioned Stanley No. 45, gifted by "Mr J Ward," with curatorial text citing a named No. 45 collector-authority (Dave Heckel) and his own type-study rarity rankings — read in full [R19, HIGH for the object's existence and accession; the relayed type-study content itself is MEDIUM, not independently verified]. The Museum of Transport and Technology (MOTAT), also New Zealand, holds a Stanley No. 45 combination plane set (object #38113) — a search-located listing only; the object page returned empty on fetch (likely JS-rendered), so it is not counted as directly read until its record is fetched and inspected [R20, MEDIUM]. No Smithsonian, Winterthur, or Mercer Museum holding was located despite direct, repeated searching this run — an honest, actively-searched gap, worth a targeted follow-up directly against collections.si.edu in a future run.
• production date ranges, independently reconfirmed across multiple sources: No. 45, 1884–1962 (~78 years); No. 55, 1897–1963 (Stanley support page, relayed) [R1][R2][R3][R9][R19].
• a dated modern reissue: the 1984 Paragon Multi-Plane (Garrett-Wade/Lee Valley, made in Sheffield, England) — real, physically described by a named owner, not independently verified against a manufacturer catalog record [R15, MEDIUM].

images this entry needs (spec for Forge — see tickets)

• The three-body-part diagram. A labeled diagram of the No. 45/55/Veritas skeleton: main body, sliding section, and fence, showing how the two skates (plus, for irregular profiles, the auxiliary center bottom) support a wide interchangeable cutter (configuration-specific: narrow Veritas blades use a guide knob instead).
• The one-fence-vs-two-fence comparison. A side-by-side: the No. 45's single fence vs. the No. 55's right- and left-hand adjustable rosewood fences (ordinarily parallel to the cutter) vs. the modern Veritas plane's single reversible fence — three engineering answers to the same registration problem.
• The "no continuous sole" cross-section. A simple cross-section comparing a dedicated Moulding Plane's full-length shaped sole against a combination-plane cutter suspended between two narrow skates with open space beneath — visually resolving this entry's central lineage-misuse finding (why the combination plane can't match a true moulding plane on figured grain).
• (optional) The priority-story timeline. A simple timeline: Miller's Patent (1870, Stanley) → Siegley's first combination-plane patent (1879, independent) → Traut's No. 45 base patent (1884, Stanley) → Stanley acquires Siegley's business (1905) → No. 55 (1897, inserted at its correct date) → Veritas Combination Plane (current).

The reviewer's corrections (14)

• BLOCKER — 1. Replace the empty safety class — Exact claim: “dangerous (misuse that injures the user) — searched directly, genuinely empty,” repeated as “injury/damage accounts — searched directly, and empty.”
• BLOCKER — 2. Remove the incomplete custom-cutter heat-treatment instruction — Exact claim: A custom cutter can be roughed with a hacksaw/grinder, filed, and then “harden[ed] by quenching.”
• BLOCKER — 3. Remove forum-derived universal operating rules — Exact claim: “tighten the adjustment screws after every pass,” and on the No. 55 “work left to right … until near full depth, then finish right to left.”
• SHOULD-FIX — 4. Correct the plow-plane definition — Exact claim: A plow plane is “a single-purpose, fixed-iron-width version” of the same skeleton.
• SHOULD-FIX — 5. Correct Traut's cited predecessor date — Exact claim: US 294,825 references Traut's prior patent “dated March 1, 1873.”
• SHOULD-FIX — 6. Identify the Traut/Schade patent as the No. 55 branch — Exact claim: A search-synthesis source calls the 1895 Traut/Schade patent “a direct precursor to the No. 45,” and the entry leaves this as an open, unverified gap.
• SHOULD-FIX — 7. Remove US 291,815 from the combination-plane proof chain — Exact claim: US 291,815 is a “closely related” Traut patent and appears under proof of existence for the combination plane.
• SHOULD-FIX — 8. Make skate support configuration-specific — Exact claim: “The cutter should be supported by at least two skates,” generalized into the correct-use section.
• SHOULD-FIX — 9. Correct the nicker/spur alignment rule — Exact claim: Spurs “must sit flush with the cutter's outer edges or chatter and tear-out result.”
• SHOULD-FIX — 10. Correct the No. 55 fence explanation — Exact claim: The No. 55's two rosewood fences generally “bisect the 90° corner angle,” each at 45° to the cutter, to prevent rocking.
• SHOULD-FIX — 11. Moderate the “steep learning curve on the modern tool” claim — Exact claim: The vintage beginner-trap pattern is “confirmed” on the current Veritas tool, making a steep learning curve one of the run's strongest findings.
• SHOULD-FIX — 12. Regrade forum and second-hand evidence — Exact claim: Named forum posts and full threads are repeatedly graded HIGH, including blade creep, grain limits, unused-condition inference, and substitute verdicts.
• MINOR — 13. Resolve the museum-source contradiction — Exact claim: The summary/provenance says two museum records were “directly fetched,” while the proof section says the MOTAT object page returned empty and was not independently confirmed in detail.
• MINOR — 14. Date volatile market facts — Exact claim: The Veritas Combination Plane is “$495 USD” and currently produced.
