Looks nice. just a sugestion for you try using hex shaft. It makes it easy to fix if something breaks and holds the gear better than a key-way. A hex broach can be purchased from McMaster or Small parts for about $100. But it is worth every penny. Team 397 has used it every year since 2002 on anything that we can, even plastic inserts to drive a pvc tube.

I see lots of practice for someone on a lathe! :)

Agreed, although we don't have a hex broach, it is really an awesome method to transfer torque between gears and shafts. (Wheels too if you're into live axles)
