Tristan, Thanks for your response.

I chose the .7 module originally because I didn't plan to add the FP motor. But since the .7 plastic was so cheap, light and the right fit I decided to give it a try. Also the stock ID happens to fit the CIM shaft OD perfectly. One of the main themes of this design was to minimize modification to the stock parts. I was going for something you could put together in a weekend. I agree though about maybe making that change. But that to me is almost another design, as this was an attempt to make the cheapest/simplest setup I could.
So you used 24 pitch successfully, great! I called out regular carbon steel, you don't think those will hold though?
Welding yes, simply because we don't have a broaching tool. Welding would be much simpler for us. The design is like a clam shell, so disassembly shouldn't be that complicated.
Apparently everyone else agrees about the motor mounts. It likely will become an addition.
