    The minimum pulley size that I could fit on the shaft was 30T, so that's what I used. By machining the pulley teeth directly into the shaft, as with my first version, a smaller pulley could indeed be used, but it adds a lot of time to the machining.

    The shafts are 35mm diameter, so it's a bit thin even with 30T as you can see from the previous one I made, here:
