Matt's Solidworks models were just the starting point for this prototype, so they don't match the final product. We're going with a refined version of what you see in the video and that's still being CADed. I didn't take any closeup photos of the gearbox before we revamped it.

The prototype itself is now in a one wheel configuration to test the difference, and the final prototype parts are being made - if we can remember how much Argon flow to use. Our experienced welder is delivering pizza tonight, so we have to order something...
