Stanley No. 23 Transitional Smooth Plane
History, Identification, Features, Restoration & Collector Value
1. Introduction
The Stanley No. 23 Transitional Smooth Plane is a versatile, mid-sized transitional plane designed for general stock preparation and bench work. Featuring a traditional wooden plane body combined with Stanley’s proven Bailey-style depth and lateral adjustment mechanism, the No. 23 represents the ideal balance between old-world woodworking traditions and emerging industrial precision.
As a jack plane, the No. 23 was intended to perform a wide range of tasks, from flattening rough lumber to preparing boards for final smoothing. Today, it remains popular among collectors and hand-tool woodworkers for its usability, lighter weight, and historical importance.
2. History of the Stanley No. 23 Transitional Plane
Stanley introduced its line of transitional planes in the early 1870s, responding to resistance from craftsmen reluctant to abandon wooden planes entirely. The No. 23 was developed as a true smooth-plane equivalent, filling the role traditionally occupied by wooden fore and jack planes.
Key historical highlights:
- Introduced: Circa 1869
- Production Period: Approximately 1869–1917
- Purpose: General-purpose jack plane work
- Market Role: Transitional alternative to metal jack planes
The No. 23 allowed woodworkers to enjoy modern blade adjustment while retaining the familiar feel and balance of a wooden-bodied plane.
3. Manufacturer Background – Stanley Rule & Level Company
Founded in 1843, the Stanley Rule & Level Company rose to prominence by combining mass production with thoughtful engineering. After acquiring Leonard Bailey’s plane patents, Stanley standardized the adjustment mechanisms that define modern bench planes.
Transitional planes like the No. 23 were instrumental in Stanley’s success, providing a gradual path from traditional wooden tools to fully cast-iron planes.
4. Design and Features of the Stanley No. 23 Transitional Smooth Plane
The Stanley No. 23 is larger and longer than transitional smoothing planes, giving it the stability required for flattening and truing boards.
Key Design Features
- Beechwood body with flat sole and square cheeks
- Bailey-pattern frog assembly mounted to the wood body
- Steel cutter (iron) with chipbreaker
- Brass depth-adjustment knob
- Lateral adjustment lever
- Rear tote-style handle (varies slightly by production era)
The wooden body helps reduce overall weight and allows the plane to glide smoothly during long planing sessions.
Typical Dimensions
- Length: ~9 inches
- Iron Width: ~1¾ inches
- Weight: Significantly lighter than cast-iron jack planes
5. Usage and Applications
The Stanley No. 23 Transitional Smooth Plane was designed as a general-purpose bench plane.
Common applications include:
- Flattening rough lumber
- Truing cupped or twisted boards
- Preparing stock prior to smoothing
- Light jointing work
- General bench planing tasks
Many modern hand-tool users appreciate transitional jack planes for extended work due to reduced fatigue compared to heavier metal planes.
6. Identification Tips
Authentic Stanley No. 23 Transitional Planes can be identified by the following characteristics:
