There is not one step pulley on that rig.

Seth, I think what you are missing is the large pulley (the left one of the two) gets it's movement from the back of the saw blade belt. It is a very unusual setup!!

The rear drive that runs the blabe should be set up with a step pulley with at least 2 steps to run blade at proper speed and it should send power to the front for feed rate. From what I see there is no way to control the feed to the front feed gear without a step pulley. All feed rates are set now by a set of pulleys that are at a fixed feed rate. A good step pulley would change this problem. Just my opinion.

I can't have a step pulley there. If I did, the result of moving the belt from one step to another would result in the belt not lining up with the larger pulley. The belt would not be able to hit the pulley squarely and would fall off to one side of the larger pulley or the other.
