Living better through CNC
Making wooden gears has always been a hassle for me. It involved transferring the pattern to my stock, drilling the shaft hole on the drill press, and tedious cutting on the scroll saw. Invariably, I spent a lot of time sanding the gear, after cutting, to clean up and correct errors caused by less than perfect saw work. It would require a minimum of 30 minutes to produce something like this 17-tooth ratchet gear.
Today, I embraced the new technology to make my gear. I designed it with V Carve Pro by drawing one gear tooth, and then using the circular array tool to generate the other 16 teeth, followed by placing a 1/4Ē shaft hole dead center.
I cut out the ratchet gear with a single tool path, and production of the entire gear took ó wait for it ó 52 seconds. Less than one minute to cut the gear and drill the hole! Plus, every tooth is perfect, and the hole is dead center.
Life is definitely better.
