Panel Plane

Identity

• name: panel plane — a use/name class, not a Stanley model name. A No. 5½ can be set and used as a panel plane, but it can also be configured as a heavy jack.
• family / category: Surfacing tools → planes → bench-plane branch, between the smoother and the jointer in length.
• one-line: a medium-length bench plane — commonly about 13–18″ — tuned for fine work, used to true and refine furniture-scale faces where a smoother is too short and a full jointer more than the work needs [PP1][P1].
• length (review fix 2): the historical class runs approximately 12–18½″, with 13–18″ as a useful common range; exact boundaries vary by maker. The evidence converges: Schwarz gives about 15″ [P1]; Moskowitz gives about 13–17″ in one place and 13–18″ elsewhere [PP2]; Norris catalog transcriptions list panel planes from 11½″ to 17½″ and jointing planes from 20½″ upward [PP11]; Sauer & Steiner offers 12½–18½″ [SS1]. Rejected claim: a single Sawmill Creek post citing unnamed "old books" gives 28–36″; it is not a named authority and is not used.
• not a panel-raising plane (review fix 10): do not infer identity from the word "panel" alone. A panel plane is a medium-length bench plane; a panel-raising/fielding plane is a molding plane that forms a raised field on a frame-and-panel door, with a skew iron and nicker [PP2][PP9]. Some casual sources shorten the latter name, creating a search-term collision.

✦ How NOT to use it

• not-for: jointer-grade accuracy on long glue edges — Moskowitz: "not as accurate as a jointer" [PP2]; panel raising.
• dangerous (review fix 5 — the holding finding). No panel-plane-specific accident report was located in the sources searched (2026-07-26). That is a research result, not a risk assessment: this is a heavy (about 7 lb for a No. 5½ [P2]) plane carrying a wide, sharp iron.
  • Sourced, panel-plane-specific: Schwarz describes the traditional infill panel plane's front bun as having four sharp, "blood-letting" corners [PP-PW-Sauer]; Sauer's K13 lowered and softened it [SS2]. On a traditional form, mind the bun corners when gripping and when the hand slides at the end of a stroke.
  • Family-derived bench-plane protocol (labelled as such):
    • Secure the work (stops, vise, holdfast) before planing.
    • Inspect handles, lever cap or wedge, and cutter retention before use.
    • Keep the cutter retracted or removed during adjustment and transport; handle the iron by its non-cutting edges; set it with the edge controlled and hands away from it.
    • Make test passes with both hands behind the cutting edge.
    • If the mouth clogs, stop; retract or remove the cutter before clearing; never clear the mouth toward the edge with a finger.
    • Control the end of the stroke to avoid hand impact against the work or bench.
    • Park the heavy plane on a stable surface away from bench edges, where it cannot fall.
    • Wear eye protection when striking an adjusterless infill iron with a hammer, and when dealing with brittle debris.
• damaging (workpiece and tool — separated from injury): spelching at the exit edge (skew or chamfer the exit edge); tear-out (read grain, reduce the cut); dragging the sole over metal or grit; rust staining (dry the steel shell after use); an unprotected iron edge in storage; setting a heavy metal plane on a finished surface where it can dent or stain it; leaning on the plane instead of pushing it, which a builder reports creates "a world of friction" [PP13].
• beginner-trap: leaning instead of pushing [PP13]; expecting jointer-grade accuracy on a long edge; trusting a name or a fixed board-length cutoff instead of a straightedge; searching mass-market catalogs for the words "panel plane" and missing the No. 5½ jack plane of the same size (the name survives mainly in bespoke infill making).
• lineage-misuse: confusing it with a panel-raising plane (see Identity); treating it as a full jointer substitute for long geometry.

Correct use

(Brief — the workbench holds the deep operation.)

• the niche: fine truing and refining of furniture-scale faces — tabletops, door panels, case sides — where a smoother is too short to help true the surface and a jointer more than the work needs [PP1][P1].
• geometry (review fix 7): by Schwarz's rule of thumb, a plane easily straightens work about twice its sole length, so a roughly 15″ panel plane is a practical straightening tool on work around 30″. Skill, initial error, stroke pattern and verification matter; on longer work it becomes progressively less reliable than a jointer — there is no sharp cutoff. Long soles bridge low spots and cut peaks; shorter soles increasingly follow existing undulations.
• wide faces: take overlapping fine passes across a wide face, not a "full-width" pass, on work wider than the iron.
• verify: check with a straightedge and winding sticks rather than relying on the plane's name or length.
• as the final plane: if it is tuned for finishing and the surface meets the finish requirement, it may be the last plane; difficult reversing grain depends more on sharpness, pitch, cutter geometry, cap-iron setup and grain strategy than on sole length.
• safe working sequence (review fix 5): see the protocol under How NOT to use it — secure work, inspect, set the iron with hands away from the edge, test passes with both hands behind the mouth, retract before clearing, park the plane safely.

✦ Matching (the workbench's first read)

• match on operation + geometry + setup, not the token "panel" (the reviewer schema notes).
• positive signals: medium-length bench plane, roughly 12–18½″; fine surfacing/truing of furniture-scale faces; jack-length body with fine-work tuning; a No. 5½ used as a panel plane; infill panel plane.
• negative signals → panel-raising plane, a different tool: skew iron, nicker, fence, fielding, beveled field, frame-and-panel door, molding profile.
• do not: collapse every No. 5½ into "panel plane" (configuration and intended operation decide); hard-code "current production absent" (bespoke commissioning is live); give market availability without a date.
• does: trues and refines shorter work and wide faces within the user's verified tolerance; takes fine overlapping passes on panels and case sides.
• suits: post-glue-up refining of furniture-scale panels and tabletops; door panels and case sides; a maker who wants one medium plane tuned for fine work.
• kit-fit:
  • pairs with: a jack or scrub for initial flattening; a straightedge and winding sticks; a smoother or scraper where the surface needs it.
  • substitution, bounded (review fix 6): a medium-length plane can true shorter work within the user's verified tolerance; use a straightedge and winding sticks, and a longer jointer when reliable long-edge or face geometry is required. A sander is only a finishing alternative after flatness has been established — it does not establish flatness.
  • cannot replace: a 22–24″ jointer for demanding long-edge or long-face geometry.
• not-for: rough-flattening rough-sawn stock (a fine-tuned mouth clogs on heavy cuts — jack or scrub); jointing long edges where a jointer is needed; panel raising.
• access: Bailey-pattern No. 5½ planes are intermediate-hobbyist tools with the same mechanism as a jack. Bespoke infill panel planes are commissioned, price on request; historical infills are collector-market items. No current price range is given (review fix 3).
• revival: modest. The Bailey-pattern route suits a maker doing frequent panel and tabletop work with one plane set for fine work; the infill route is a bespoke and collector tradition that remains live (Sauer & Steiner). Bill Carter's origin story — his first plane built from panel-plane plans — is a story about becoming a planemaker [P10].

Anatomy

Deltas only; shared bench-plane parts are in Bench Plane (Western).

• sole length — about 12–18½″, commonly 13–18″ (see Identity). Sole length and flatness are the principal geometric factors in bridging high spots.
• width and mass — irons of about 2¼–2¾″ on the examples here; width and mass affect effort and momentum, not flatness by themselves (the reviewer mechanical notes) [P1].
• fine-work tuning, not one fixed anatomy (review fix 8): the class is defined by medium sole length plus fine-work tuning. Tight mouth, fine cutter projection, appropriate pitch, a sharp iron, and — where present — a cap iron set for the intended shaving are configurable strategies. Schwarz treats pitch and sharpness as the most important smoothing variables and calls chipbreaker claims contested [P1].
• construction varies: wooden, infill (dovetailed or screwed steel shell with hardwood infill; early Spiers with a fixed bridge and no adjuster [PP3]; later Norris adjusters [PP-GB]), Bailey, Bedrock-style, bevel-down or bevel-up, and bespoke. Anatomy deltas are variant-specific.
• handles: traditional infills carry a front bun and rear tote let into the infill; on some traditional forms the bun has sharp corners (see How NOT to use it).

Variations (living) — with dated availability states (review fix 3)

Trades

• Fine furniture making and cabinetmaking — tabletops, door panels, case sides [PP1][P1].
• No other trade association was located in the sources searched on 2026-07-26.

Lineage

Family lineage lives in Bench Plane (Western).

• place in the family: between the Smoothing Plane (Western) (about 8–10″) and the Jointer Plane (Western) (22–24″+) [P1].
• ancestors: the wooden panel plane, which per Moskowitz existed in wood for over a century before the first metal examples [PP1].
• the metal/infill branch: Robert Towell (London, active c.1810–1863) made some of the first metal panel planes in the 1830s–40s, adapting his miter-plane construction with a bevel-down iron and room for a handle (Moskowitz) [PP1]; Spiers of Ayr and later Norris developed the form. Towell is treated as an early pioneer, not the established inventor: Moskowitz's own text says "some of the first" while his title uses "inventor" (the reviewer factual notes).
• ★ Finding 1 — the name largely disappeared from mass-production catalogs but remains live among bespoke infill makers (review fix 1). Lie-Nielsen catalogs the comparable 14¾″ form as a No. 5½ Jack Plane (its page shows $450 and states "This product is not available" — checked by the reviewer, 2026-08-02) [P2]. Sauer & Steiner offers made-to-order No. 1 panel planes under the historical name — its current page, headed "No. 1 Panel," offers lengths from 14½ to 18½″ plus a 12½″ Junior, with price on request and a commissioning link [SS1]. Earlier: Spiers's c.1851–58 brochure names a "pannel plane" at 13½″×2¾″ [PP3]; Norris catalogs named the "Dovetailed Steel Jointing & Panel Plane," dividing jointing and panel by length [PP11].
• descendants / contemporaries: the Bailey/Stanley No. 5½ (cataloged by Stanley as a jack plane); modern infill revivals (Carter, Holtey, Sauer & Steiner); Sauer's K13 redesign (Finding 3).

History

• Spiers of Ayr made panel planes in documented sizes of 11½″ to 14½″, with surviving examples at 13¾″ and 15½″ (dealer listings) [PP5]. Alexander Mathieson & Sons (Glasgow) also made infill panel planes [PP6].
• Norris adjuster. GB191311526A, Thomas James Norris, "Improvements in Planes" — filed 17 May 1913, published 24 July 1913; the abstract covers depth and lateral correction [PP-GB]. The 1923 improvement is a separate patent, GB199198, not a revision of the first (Lee Valley featured-patent note) [LV-N].
• Norris founding date. Norris's advertising claimed 1860; a specialist dealer (The Best Things) reads the evidence as closer to 1880 [PP7]. Recorded with the nature of each source; the company-history question belongs to the family entry.
• ★ Finding 2 — the class is a flexible medium-length range, not a rigid standard. Norris's own catalogs (as transcribed) separate visually similar No. 1/A1 planes into panel and jointing planes by length alone [PP11]; see the length note under Identity.
• ★ Finding 3 — development within the metal/infill branch. In 2010 a customer asked Konrad Sauer (Sauer & Steiner, Ontario) to "re-think the panel plane"; ten months later came the K13 (2011), a pound lighter with a low, softened front bun [PP-PW-Sauer][SS2]. Reviewing it, Schwarz called the traditional infill form "fairly useless" and its front bun's four sharp corners "blood-letting" — a personal evaluation in the context of the K13 redesign, not a settled verdict on the type [PP-PW-Sauer].
• modern revival: Bill Carter's first metal plane (1983) was built from panel-plane plans [P10]; Karl Holtey began by reproducing the Norris A1 panel plane [P9]; Sauer & Steiner made traditional panel planes before the K13.

✦ Human side

• Named makers: Robert Towell [PP1]; Stewart Spiers [PP5]; Thomas Norris & Son [PP7][PP11]; Alexander Mathieson & Sons [PP6]; Bill Carter [P10]; Karl Holtey [P9]; Konrad Sauer and Joe Steiner [PP-FWW-Sauer]; builders Jim Yehle, Jerome Schueller, Wayne Anderson, and adjuster supplier Darryl Hutchinson [PP12].
• Jim Yehle's build log: "This panel plane is the infill-plane equivalent of the Bailey-style jack plane, with a sole length of 14″," modeled on Mathieson's side profile with a Norris-A1-style adjuster [PP12].
• A builder's technique note (LumberJocks, single post): an 18″ Spiers-kit panel plane is "heavy for its size... a good plane to use if you remember to push it and not lean on it" [PP13].
• David Charlesworth uses a No. 5½ panel plane "for most tasks," per Schwarz [P1]. The tasks are not specified, so this is not used to support any particular substitution (review fix 6).
• Schwarz vs. the traditional form — his "fairly useless" and "blood-letting" remarks are his own evaluation, retained with that limitation (the reviewer factual notes).

✦ Proof of existence

• Maker naming: Spiers's c.1851–58 brochure ("pannel plane," 13½″) [PP3]; Norris catalogs naming the "Dovetailed Steel Jointing & Panel Plane" — via norrisplanes.com, a specialist catalog transcription of 1908, 1914 and 1928 catalog data, not an independently inspected original (review fix 9) [PP11]; Sauer & Steiner's current "No. 1 Panel" page [SS1].
• Patent: GB191311526A (Norris adjuster, 1913) and GB199198 (1923 improvement) — adjuster patents used on panel planes, not a patent for the panel plane as a class [PP-GB][LV-N].
• Surviving objects (dealer-documented): Spiers panel planes at 11½–15½″ [PP5]; Norris A1 panel planes [P5][P6]; Towell panel planes photographed against a c.1910 Norris [PP1].
• Scoped negatives (review fix 9): no patent for the panel plane as a class and no museum accession specific to a panel plane were located in the sources searched on 2026-07-26.

The reviewer's corrections (10)

• BLOCKER — 1. Replace the false “no current maker” headline — Exact claim: “NO CURRENT PRODUCTION MAKER SELLS ANYTHING CALLED A ‘PANEL PLANE’,” repeated in the summary and Finding 2.
• SHOULD-FIX — 2. Resolve the manufactured length dispute — Exact claim: “The length is disputed even among named authorities,” supported by Schwarz at about 15 inches, Moskowitz at 13–17 inches, and a 28–36-inch anonymous forum post.
• SHOULD-FIX — 3. Correct the current-product and price language — Exact claim: Lie-Nielsen “sells” the No. 5½ for $450; the access section treats it as an available purchasing route; old Sauer & Steiner prototype prices and Holtey figures are presented as the current market.
• SHOULD-FIX — 4. Repair the Stanley No. 5½ specification and dating — Exact claim: “vintage Stanley No. 5-1/2 — Bailey pattern, 15″×2⅜″, produced ~1880s–90s through much of the 20th century.”
• BLOCKER — 5. Rebuild the safety class instead of declaring it nearly empty — Exact claim: “dangerous: honestly near-empty,” with only a dropped tool and a finger clearing a clogged mouth offered as inference.
• SHOULD-FIX — 6. Remove unsupported substitution claims — Exact claim: A panel plane “can substitute for: a jointer on shorter panels/edges (per Charlesworth’s ‘most tasks’ use)” and a powered jointer plus random-orbit sander “cover the same practical ground.”
• SHOULD-FIX — 7. Correct the “twice sole length” mechanism and thresholds — Exact claim: Beyond roughly twice its sole length the panel plane “starts bridging the wave rather than removing it,” paired elsewhere with a 4-foot threshold.
• SHOULD-FIX — 8. Do not define the whole class by a close-set cap iron — Exact claim: The one-line definition and anatomy describe every panel plane as carrying a smoother’s “tight mouth and close-set cap iron.”
• SHOULD-FIX — 9. Downgrade negative-search and source-grade claims — Exact claim: “no patent found,” “no museum-accession record found,” and retailer/catalog negatives are treated as strong findings; trade articles, dealer pages, and search summaries are repeatedly graded HIGH or “primary manufacturer …
• MINOR — 10. Tighten the panel-plane / panel-raising-plane wording — Exact claim: The name “is sometimes shortened, informally and incorrectly, from panel raising plane,” followed by claims of a “naming collision.”
