The stock Sherline Motor sheave. The belt is a rather smallish composite belt. When I first ordered the Sherline spindle head assembly, I ordered an extra belt, so I had two on hand. I decided to machine the sheaves so that it would use two belts simultaneously for strength.
My first task was to determine the geometry of the belt. The included angle, iirc (don't quote me here) was 30 degrees. I used a caliper to determine the factory groove depth and width."COOPER" DOUBLE SHEAVE PULLEY 1", rigid eye One-piece cast construction with triple copper/nickel plating and solid brass or Brass-plated sheaves Designed for indoor or outdoor use with rope or cord Pulley is highly resistant to rust and corrosion References National No. 223- 420 Bulk, References National No. 223- 420, Designed for indoor or outdoor use with rope or cord, Pulley is highly resistant to rust and corrosion.
