Do you think these sheaves will work?

http://home.maine.rr.com/rlma/Sheaves.jpg

I made an arbor, chucked them in an electric drill, and went at them
with progressively finer grits of sandpaper. The pits feel much less
alarming than they look and you can't even feel them with a finger.
The sheaves are so smooth, I think they would work even if
non-turning. I also radiuses and smoothed all the contact edges on
the box.

I moved the sheave that had no wire marks (never used for anything on
this boat) to the main halyard position since that is the one that
will see the most rope movement.
