Could you give more info on the "continuous-rotation pot?" Does it have a dead zone?
From Digi-Key....made by Bourns. 6639S-1-103-ND

My controls engineer may have to clarify, but I don't recall any dead band. They simply rollover at the zero point.

I'm assuming the actual tensioner pulleys are like a black delrin? If so, have you had any issues with wear and tear on them in your findings?
This unit has low hours, but I'm planning to see some wear over time. The black delrin rotates quite smoothly on the aluminum cam. This rolling action helps minimize wear.

How did you machine it with the guide grooves?
These pulleys were made on a simple lathe with a parting tool.
