Stanley No. 24 Transitional Smooth Plane

History, Identification, Features, Restoration & Collector Value

1. Introduction

The Stanley No. 24 Transitional Smooth Plane is a full-size transitional smoothplane designed for demanding bench work and primary stock preparation. Combining a traditional wooden plane body with Stanley’s proven Bailey-style depth and lateral adjustment system, the No. 24 offered woodworkers the power and reach of a large jack plane with the precision of modern blade control.

As one of the larger transitional models, the No. 24 was intended for flattening wide boards, truing long stock, and preparing lumber prior to jointing and smoothing. Today, it is valued for its capability, lighter weight compared to cast-iron planes, and its important place in the evolution of Stanley hand planes.

2. History of the Stanley No. 24 Transitional Plane

Stanley introduced transitional planes in the early 1870s to address resistance among craftsmen who preferred wooden-bodied tools. The No. 24 was developed as a large smoth-plane equivalent, closely matching the size and function of traditional wooden smooth and jack planes.

Key historical highlights:

Introduced: Circa 1869
Production Period: Approximately 1869–1943
Purpose: Heavy stock preparation and general bench work
Market Role: Transitional alternative to metal jack and fore planes

The No. 24 appealed to carpenters, cabinetmakers, and joiners who wanted increased capacity without the weight of a full cast-iron plane.

3. Manufacturer Background – Stanley Rule & Level Company

Founded in 1843, the Stanley Rule & Level Company became the world’s leading plane manufacturer after acquiring Leonard Bailey’s patents. Stanley’s standardized adjustment mechanisms revolutionized woodworking by improving accuracy, repeatability, and ease of use.

Transitional planes like the No. 24 were critical in helping Stanley convert traditional craftsmen to modern plane designs while preserving familiar wooden-plane handling characteristics.

4. Design and Features of the Stanley No. 24 Transitional Smooth Plane

The Stanley No. 24 is among the longest and most capable transitional planes produced by Stanley.

Key Design Features

Beechwood body with long, flat sole and square cheeks
Bailey-pattern frog assembly mounted securely to the wood body
Steel cutter (iron) with chipbreaker

5. Usage and Applications

The Stanley No. 24 Transitional Smooth Plane was designed for heavy-duty bench work.

Typical applications include:

Flattening wide or rough-sawn boards
Truing twisted or cupped stock
Preparing lumber for jointing and smoothing
Light fore-plane work
General carpentry and cabinetmaking tasks

Modern hand-tool woodworkers often favor large transitional planes for aggressive stock removal without excessive tool weight.

6. Identification Tips

Authentic Stanley No. 24 Transitional Planes can be identified by the following characteristics:

“STANLEY” stamped cutter
Long wooden body with mounted metal frog
Bailey-style depth and lateral adjustment mechanisms
Proportions consistent with a large jack or fore plane
Original beechwood body and intact adjustment hardware

Earlier examples typically feature heavier irons and more refined fittings, while later versions may reflect cost-saving changes.

7. Restoration of the Stanley No. 24 Transitional Plane

Despite its size, the No. 24 is straightforward to restore.

Typical Restoration Steps

Remove iron, chipbreaker, and adjustment hardware
Clean and de-rust metal components
Lightly flatten the wooden sole using a flat reference surface
Clean and lubricate all moving parts
Repair minor cracks or checks in the wood body if present
Sharpen the iron for efficient stock removal
Reassemble and test on softwood and hardwood

Restoration Tip: Because of its length, take extra care to maintain sole flatness across the entire body.

8. Collectability and Value Today

The Stanley No. 24 Transitional Smooth Plane is moderately collectible and prized for its usability.

Typical Value Ranges

User condition: $50–$90

Excellent examples: $200+

Value is affected by:

Condition and straightness of the wooden body
