Joined the Gear crowd

[Norm W]

This crowd is getting bigger. It wasn't a lathe gear that needed to be built, a garage door opener had eaten a worm wheel gear. I don't have a hob so a fly cutter had to serve. Instead of making an index wheel I just used the old gear. The gear teeth are angled so the old gear allowed me to match the angle for the blank. The old gear was some sort of plastic, the new one is aluminum. The fly cutter was ground to match the worm thread. This maybe should have been in machining, but I had to fab the jig to machine it. I sure it would have been cheaper to buy a new gear, but the challenge was there.
