How to make wooden gears

This page also available in Spanish Some people are intimidated at the prospect of making their own wooden gears for the screw advance box joint jig. So I figured I'd cover the topic of gear making in a bit more detail. You can click on any image in this article to get a larger view. The method I use to make the gears for the box joint jig is the same as for the gears for the wooden router lift, but I'll focus on the ones for the box joint jig in this article. It's vital to use good plywood for the gears. Start by making a template for the gear shape. Glue the paper template onto a piece of birch plywood about 10 mm (3/8") thick. Next, use an awl to punch a divot in the center between every two gear teeth. Use a 5/16 (8 mm) brad point drill to drill out a hole in every space between the teeth. 5/16" is just the right size for the tooth spacing used in the gears for the box joint jig or the router lift. The divots made with the awl help to center the point of the drill on every hole.

Gear template generator This free online gear template generator is designed for making scale accurate paper gear templates which you can glue onto wood and then cut out with a bandsaw. I recommend printing the gears with an ink jet printer. Even cheap ink jet printers print very scale accurate but Not all laser printers are accurate. You can still access the old (pre 2015) Flash based gear geberator Getting the printout to scale correctly, avoiding cropping Different browsers print at different scales depending on browser type and printer configuration. Use an ink jet printer I recommend using an ink jet printer. Printing the gear templates To print the gear template, use the 'Print' button, instead of printing the web page from the browser. The gear generator program that I created and sell doesn't need the scale calibration, and can paginate across many pages for larger gears. Some notes about gear design and this gear template generator This gear template generator generates shapes for involute spur gears.

File:Hubble ultra deep field high rez edit1.jpg gary's wooden clocks George Perzel George sent me these pictures of a clock he made from the plans he downloaded from this website. George laser cut the gears using the info from the dxf file. What's really neat is that George made a half scale model from the plans. This Model was made by George to better understand relationship between all the parts. George plans to do one half size out of better wood and see how it works. Get the Gears already cut from George on e-bay George has the plans available to make a full size set of gears and pinions at a reasonable price for aspiring horologists and wood workers. Clcik the link below: Gears On E-Bay A complete set of 12 gears/pinions which will enable building Gary's wooden clock, plans for which can be freely downloaded at Gary's downloads This set includes 5 main gears, an escapement gear, 5 pinion gears, and a ratchet gear. The ratchet and pinions are laser-cut from 1/4" rock maple which was cut over 30 years ago and is extremely stable and very hard.
