Jerry,
Once again, your attention to detail, craftsmanship, and pioneering solutions to improve / enhance Destiny are remarkable. Question though on your masthead sheave box assembly. From the photos you posted it appears there would be interference problems with the sheave axle pins and the outer wall of the mast extrusion. You mentioned you have chosen Harken sheaves, what type of pin is being used to hold them in that beautiful stainless steal assembly? Are they clevis pins, machined pins of bronze, stainless, do they have a head on one side and a cotter hole on the other? Or, maybe they are pressed in? Just really curious because I see you don't have the sheaves installed yet.

Thanks for the inspiration!
