I've toyed with the idea a few times. In order for me to even get started I need to model the gearbox and I just haven't had the time to do it. If I did I would have the gearboxes cast in bronze then CNC the remaining geometry using a fixture. I would NOT do the gears though, I've never cut gears before and wouldn't want to go down that road.

Steps needed for me to get this done:

Model the gearbox
Build a milling fixture (not terribly difficult)
Create the CAM for the milling operation
Develop a relationship with the foundry down the road and see if they have any interest in casting this.
3D print a casting positive (to allow for shrinkage)

Then go from there.

I'll keep thinking about it.
