Is it a correct statement that it is impossible to stall the top motor? If so it seems like it'd be a good candidate for a lighter and more efficient open-air motor (new 775, e.g.) so long it's geared correctly.

you can still stall out the motors and while it would work to a degree the total capable speed and power is still reliant on both of the motors so if you used a 775 you will lose in both regards compared to a cim.

I'm curious about that worm gear that you've got. It looks 3D printed - is that right? Can you give us some specs and tell us how you made it? Does it seem like it will be sturdy enough to hold up well?

they are NOT 3d printer. They are plastic though(nylon?)they are actually very common garage door opener gear sets you can buy at sears. Though they are twice as cheap online. In fact, andymark uses the exact same set(but they hex broach theirs) on one of their 90 degree transmissions. We used two sets last year to drive our elevator mechanism and they held up just fine.

As far as specs/how it was made take a look at the CAD files.
