Stanley No. 55 Universal Combination Plane – The Most Complex, Capable & Iconic Multi-Function Plane Ever Made

1. Introduction

The Stanley No. 55 Universal Combination Plane is widely regarded as the most ambitious hand plane ever created. Designed as a complete “plane shop in a box,” the No. 55 was engineered to handle plow grooves, dados, rabbets, beads, hollows and rounds, sash work, reeding, fluting, and hundreds of molding profiles using a massive arsenal of cutters and adjustable components.

With its four skate sections, dual fences, sliding and tilting features, multiple adjustment rods, and a standard cutter set that eventually exceeded 55+ irons, the No. 55 stands as the pinnacle of Stanley’s hand plane engineering.

This article provides a complete guide to the Stanley No. 55 Universal Combination Plane—the most versatile and collectible combination plane ever produced.

6. Restoration of a Stanley No. 55 Plane

Restoring a No. 55 can be more involved than other combination planes due to the many components.

Typical Restoration Steps

Fully inventory all parts (skates, rods, two fences, depth stops, spurs, cutter box).
Disassemble all sections, including skates and fence tilters.
Clean rust from hardware using Evapo-Rust.
Lightly lap skates, but avoid over-thinning them.
Polish rods for smooth fence travel.
Sharpen all cutters—profiled cutters require slip stones.
Oil the rosewood or hardwood fences, but do not refinish unless necessary.
Reassemble according to original configuration.
Verify alignment of both fences and skates.
Test-cut simple grooves and beads before molding profiles.

Optional Upgrades

Custom storage box for cutters
Replacement cutters from modern makers
Polished skates for reduced friction

Restoration Mistakes to Avoid

Sanding or reshaping fences
Filing cutter profiles incorrectly
Misplacing screws (many are unique to the 55)
Removing japanning excessively
Over-lapping the skates

A restored No. 55 is a museum-grade tool—and a functional one.

7. Collectability & Value

The No. 55 is one of the most collectible Stanley planes ever made.

Typical Value Range

User-grade plane only: $200–$325
Good condition w/ partial cutters: $325–$475
