Redesigned T-20, T20-M

You may want to reconsider your band design and copy the spiral design as it is self energizing with low input force to high friction force. The redesign will be more like an on off switch for the self energized rotation and hard to engage in the other direction

You bet. Make everything simple to fab using run of the mill machines. As far the bands, I have spoken to a company that applies the very high end brake pad materials to race pads. Cant use ceramic where there are bearings but this stuff is supposed to be good. I have about 270 degrees of wrap with very wide bands. They will cinch when drawn. if it is not enough for use with 40 HP then I have another plan that is a bit more expensive that uses hydraulic systems like motorcycles. Good point though.
