Stanley No. 5½ Bench Plane – The Wide Jack Plane for Precision Flattening & Smoothing

1. Introduction

The Stanley No. 5½ Bench Plane—often referred to as the wide jack plane—is a favorite among woodworkers who desire additional weight, width, and stability in a versatile mid-sized hand plane. Positioned between the standard No. 5 Jack Plane and the No. 6 Fore Plane, the 5½ provides the perfect combination of mass, power, and precision for flattening, truing, and even fine smoothing.

With its 15-inch body and 2⅜-inch iron, the No. 5½ is heavier and wider than the standard jack, making it exceptionally effective on larger boards and highly figured hardwoods. Its strong presence and balanced feel also make it a top contender for a “one-plane-does-most-tasks” setup.

2. History of the Stanley No. 5½ Plane

Stanley introduced the No. 5½ in the late 19th century, expanding its Bailey bench plane lineup with a wider, heavier jack plane aimed at professional cabinetmakers and furniture builders.

Historical Highlights

• Debuted in the 1880s–1890s as demand grew for a heavier jack plane
• Manufactured through nearly all Bailey type eras
• Became popular during the 1890–1935 Golden Age of Stanley planes
• Saw reduced quality after WWII with simplified machining
• Late models used beech or plastic handles
• Not produced in the Bed Rock line (though Sargent and others made equivalents)

Today, early and pre-war Stanley No. 5½ planes are sought after for their craftsmanship and excellent steel quality.

3. Manufacturer Background – Stanley Rule & Level / Stanley Works

Founded in 1843, Stanley became the world leader in hand plane manufacturing thanks to the Bailey adjustment system, precision machining, and large-scale production.

The No. 5½ fits into Stanley’s hierarchy as a specialty jack plane offering:

• Wider blade and sole for better surface contact
• Increased mass for flatter, more stable planing strokes
• Excellent control on hardwoods
• Versatility between a jack and a fore plane

Woodworkers who prefer heavier planes often praise the No. 5½ as the ideal hybrid tool between roughing and smoothing.

4. Design and Features of the Stanley No. 5½ Bench Plane

The 5½ is designed for stability, power, and smoothness.

Specifications

• Length: 15 inches
• Iron width: 2⅜ inches
• Weight: approx. 5½ lbs
• Materials: cast iron body, brass hardware, rosewood/beech knob and tote

Core Features

• Wide, heavy body for improved flattening
• Bailey-style adjustable frog
• Lateral adjustment lever
• Precision-ground sole and cheeks
• Brass depth adjustment wheel
• Chipbreaker and cap iron assembly
• Low knob (early) or tall knob (post-1930s)

Why Woodworkers Love the No. 5½

• Heavier and more stable than the No. 5
• Narrower and easier to manage than the No. 6
• Excellent for flattening medium-sized surfaces
• Works beautifully with a finely honed smoothing iron
• Ideal for figured hardwoods

Many modern hand-tool woodworkers consider the No. 5½ the best single plane for someone who wants a “jack-of-all-trades”.

Type Study & Identification Guide

The Stanley No. 5½ has type variations that align with the standard Bailey Type Study (Types 1–20).

Early Types (1–7)

• Three patent dates
• Early rosewood knob and tote
• No frog adjustment screw on earliest models
• Highly collectible

Middle Types (8–15)

• Improved frog design
• Transition from low to tall knob
• Refined machining and castings
• Best performance-to-collector-value range

Later Types (16–20)

• Beech or plastic handles
• Post-WWII machining shortcuts
• Orange background lever-cap logo
• Still excellent user planes

Because the No. 5½ was less common than the No. 5, early types command higher premiums.

5. Usage & Applications

The No. 5½ excels in both roughing and smoothing tasks due to its size and weight.

Common Uses

• Flattening and truing medium-large boards
• Removing machine marks
• Preparing panels and tabletops
• Rough smoothing before fine finishing
• Working highly figured hardwoods
• Jointing narrower boards

It is especially valued for tasks requiring controlled weight, consistent passes, and broad surface contact.

6. Restoration of a Stanley No. 5½ Plane

Restoring a 5½ follows the same steps as standard Bailey planes but requires careful handling due to its larger iron and heavier body.

Typical Restoration Steps

1. Complete disassembly
2. Rust removal (Evapo-Rust, citric acid, or electrolysis)
3. Sole flattening on granite or glass
4. Frog tuning for full, solid seating
5. Sharpening the 2⅜” wide iron
6. Chipbreaker tuning
7. Handle restoration (rosewood preferred)
8. Reassembly & lubrication

Mistakes to Avoid

• Over-lapping the wide sole
• Removing original japanning
• Replacing rosewood handles
• Polishing brass excessively

A tuned No. 5½ can perform as well as premium modern bench planes in the $300–$450 range.

7. Collectability & Value

The 5½ is more collectible than the No. 5 due to lower production numbers while still being practical for everyday woodworking.

Typical Value Range

• User-grade: $50–$90
• Good pre-war examples: $90–$150
• Early types: $150–$275
• Near-mint examples: $300–$450+

Factors Affecting Value

• Type number (early types worth significantly more)
• Japanning and casting condition
• Handle material and finish
• Blade originality
• Overall completeness

High-condition pre-WWII examples are especially sought after.
