Re: pic: 1918 Quad Drive Device
The green tube is a pool noodle. The spindle is a 3/4" aluminum tube powered by an FP motor thru an AM planetary gearbox and an AM Nano. It spins maybe 300 rpm without a ball in it. We discovered by accident that the noodle slips on the spindle when holding a ball. It keeps enough force on the ball to hold it and let us back up or turn, but doesn't stall out the motor when we get a good pinch between the roller, ball, and floor.
