Team 1468 used pneumatic tubing from the KOP. The central spindle was a 1" square piece of 8020 tubing with holes drilled through it for the tubing. It was actually one long piece of tubing which was threaded continuosly from one end of the 40" long spindle to the other. This gave us loops sticking out of the spindle to push the balls up. We found that this worked out better than having small tubing sticking out. Tapping 1/4-20 threads into each end of the 8020 made it real easy to bolt on bearings to the spindle.
