Turrets can be used to rotate a mechanism without having to move the whole chassis.
Some tricks for the bearing stack setup:
Use more stacks than you think we shoot for only a couple inches between each stack. Seems excessive but it runs much smoother
Anodize the plate if possible, helps keep everything running smoother.
Run an odd number of stacks, this (in theory) will reduce how well toleranced everything will need to be to run smooth
We love running a 20dp gear because we can get a 2stage reduction on turret with minimal effort and the backlash is extremely low. 25chain is the next best option.
