Free Wood Gear Generator | Wooden Clocks, Automatons & Scroll Saw Art

Designed specifically for woodworkers, kinetic artists, and horology enthusiasts. Wooden gears require specialized tooth spacing and clearance to prevent binding from wood grain expansion and humidity. GearDXF creates generous tooth clearances, decorative spoke cutouts, and 1:1 scale printable PDF patterns.

Key Features

• 1:1 physical scale PDF printouts designed for spray adhesive and scroll saw cutting
• Custom backlash tolerances to prevent tooth binding on wooden clock mechanisms
• Decorative spoke cutout patterns: circular, slotted, elliptical, and vintage curved arms
• Generates tooth profiles optimized for Baltic birch plywood and hardwoods
• Simulate mechanical clock speed and escapement gearing in real time
• 100% free with no registration or watermarked patterns

Frequently Asked Questions

What is the best wood for making functional wooden gears?

High-grade Baltic birch plywood (aircraft grade) is the gold standard because its alternating thin veneers resist warping and tooth breakage. Hardwoods like hard maple and cherry also work well.

How much backlash is recommended for wooden gears?

Wood expands and contracts with atmospheric humidity. A backlash setting of 0.5mm to 1.0mm (depending on gear size) ensures wooden gear trains run smoothly without seizing.

How do I cut out wooden gears accurately?

Export the 1:1 scale PDF from GearDXF, print at 100% scale on paper, adhere it to your wood blank using temporary spray adhesive, drill the center hole first on a drill press, and cut the teeth with a scroll saw using a #2/0 or #3 blade.
