Nice Job. I too made my first gear 6 months ago. I didn't want to , but the gear I needed would have been a custom job, and the price would have been prohibitive. I decided to make it. I learned a lot about gears , gear profiles and stadards, and gear making, in the process and I wouldn't hesitate to make more given the need. For some gears that are easily available, it's probably not worth the time and effort, given the fairly cheap prices, for off the shelf profiles.The tooling investment required to make a gear can be quite high unless you already have a dividing head and cutters. There is something to be said about the satisfaction and confidence building that such a project provdes.
