I know it just as a spinning table. I built my own table using a decent sized DC motor a couple of pulleys, a shaft, and I installed an electronic motor controller on mine. I can control the speed by turning a potentiometer. In fact tomorrow I am making an adjustment to my table. Maybe I'll post some pictures after I upgrade it. You don't need the electronic motor controller on it like mine but most DC motors will provide too much RPM so you need to use pulleys of different sizes to reduce the speed. Small pulley on the motor shaft and larger pulley on the offset shaft will give you a reduction. The other thing you need though is a spinning plate that goes over the shaft that your block will sit on. For that Part I just picked one up from JW Hats. In fact JW will build you an entire spinner assembly that you mount to your own table but it is expensive (that's why I made my own ).
