I am going to replace my masthead sheave with a delrin sheave, my original was tufnol sp? I just sent a quote request off to a friend who owns a machine shop for an aluminum one attached is a drawing in jpg format . I was also thinking of doubling up on the sheave (putting two side by side) so as to have a spare or using it for my jib. According to my calculations an aluminum one made like my drawing would weigh 22.4 oz where the delrin would be 12.75oz delrin is much tougher than tufnol or phenolic and the black color is uv resistant I bought enough delrin to make several if anyone wants to try one.. chris
