Re: Adding a topping lift, or the heck with sheaves
I have used those delrin sheaves from McMaster to replace a sheave in my boom.
One nice thing about the delrin is I was able to easily adjust the shape of the sheave a bit by sanding the sides to make it "thinner" and a drill bit made the pivot hole slightly larger to fit my application.
So you don't need an exact fit but as close as possible given the sizes of delrin sheaves McMaster Carr sells.
