Re: [Amel Yacht Owners] Toe pulley (headsail)

I have emailed Bernard (without reply to date) about any testing he may have done relative to slippage and recommended line size/composition.
Peter de Groot has lightly tested this with success. Since I have Bernard’s sheaves and will not be on Aletes until February I will be eager for your evaluation and see if you find like Peter that these work.
Does anyone else have experience with Bernard’s sheaves?
If there is insufficient friction, a possible modification might be to drill into the slot/groove all around to create teeth. See sketch. Drill size and spacing is engineering far beyond my capability. Gut feel is between ½” and 5/8” diameter and 12 to 16 in total.
I am also a bit concerned about sharp edges chafing the line. May soften them a bit with sandpaper.
Thoughts so far pending other’s insightful comments.

Yeah...I bought a set and I'm thinking the same thing, but maybe using Vectran with a polyester cover and pulled tight it may be OK....
I'm not back on the boat until the end of January, I'll install them then, test them out and report back.
