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.



Dave Dalsin had a good usable wax mold for the kidney housing and pointer, unfortunately he gave it away to another member who probably has good intentions but has done nothing with it. I cant remember who it was right now, but I did approach the current holder of the mold a few months back and he was trying to get to the project and not willing to pass the torch. Hopefully he is reading this thread and will chime in. It would be nice if someone, who is willing to take the mold to the next step,  get the mold that Dave made. I will state for the record that I am in for 2 Kidney housings(top and bottom) and I dont need the gears. I would pay up to 300 for the 2 pieces if anyone decides or is trying to decide whether to do this or not.
