Installing capstans is a standard part of our grand damper tray replacement
process. Indeed, it has now become a standard part of rebuilding any
existing damper tray. If the original tray won't accept capstans it gets
replaced.

I teach this as part of my damper class and have a drawing illustrating most
of what you need to know. For a copy of this drawing send me a
self-addressed, stamped envelope. (It's a CAD drawing and unless you have
the same program it won't do you much good via e.mail.)
