Hi Wayne,

Thanks for your reply.

Would the drill rod roller by itself (with no liner on the ID) not wear
OK for a slow moving hand operated device ?

The part is so small, the bushing wall is only 1/32" thick, and that is
without any type of liner on the ID, that's just making the bushing out
of solid drill rod. It seems machining or making a thin walled liner to
go on the ID will be very difficult.

The bushing OD cannot be any larger than 3/16".

Thanks
John
