Basics
Hello,
You'll find directions for making rope-stropped blocks in the "Apprentice". Also sheave size recommendations. As for the grommet materials, what are the loads? A properly-made grommet should be close to twice the strength of the rope it is made from. How does that compare with the loads on the block?
Is it "Delrin" you are after? I'd go to Zephyworks; they make fine bushed Delrin sheaves.
Fair leads,
Brion Toss
