Excellent bit of tooling there. I am going to make me a jig like this when I need a similar gear. Thanks for the tutorial.

No problem. Yeah my first though was to use a large piece of 2x6 wood. It is about 14" long. I was going to make several holes then use a belt or orbital sander to do several gears at once, but that seemed like overkill. One at a time is ok because it litterly only take ls a few seconds to sand down.

By the way the metal is there so you do not sand down the wood too much.

I did that on my first attempt. But if you had some mild steel or aluminum that would likely be best.
