its a gear…its a ball…its BOTH!!!

That smells… ::sniff sniff:: a lot like a WPI MQP :slight_smile: Can we say “Continuously Variable Toroidal Transmission”? I get the feeling the shop’s going to be occupied for quite awhile with some stumped machinists!

That’s seriously cool. How’s it attached to… well… anything?

It’s not… its just a simple gear copied and rotated to have what looks to be 6-8 gears with just the midpoint of the center’s on the first gear. No feasible use that I can think of.
