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. On Set: Empire Strikes Back. A Policy Of Conscious Aggression. Glass.
