Rotation Systems

[Andrew Blair]

Our original plan was to have a shooter on a turret, using a lazy-susan bearing from Mcmaster. Well, we got the shooter on the bearing, ran out of time, locked the bearing and eventually ended up just ditching the thing. But, the Mcmaster bearing was rated to a very high weight load, only 30 dollars, light, large ID, very tight for the price, and seemed very tolerant to side thrust. Very similar to the Lee valley bearing, and probably the same one UCGL_Guy's team used. Overall, nothing but good things to say about it, especially with a little weight on it.

Last year, we used an aluminium wheel hub for our arm. (I thought it was a great idea this year, too.)

This year, it was a turntable similar to what you would find at Home Depot for swing-out tables. (about 6"~8" diameter)
