Has anyone discovered any new methods to treat pulley keys? (How do we spell pulley, pullie, pully--beats me). This term refers to enlarged center rail pin holes in the key. We've heard of sizing the hole with dilutted glue. Which glue? I've had limited success with this method. Then there's the tool which drills out the key bottom to fit in the inserts (see APSCO Supply Catalog Page 23, No. 16201). Are inserts available in various sizes?
