Has anyone discovered any new methods to treat pulley keys? (How do we spell pulley, pullie, pulle, pully--beats me). This is the condition where the center rail pin holes in the keys become enlarged causing noise. We've sized the holes with diluted glue. Which glue is best? It doesn't always work. Then there's the tool which routs out the bottom of the key and an insert is glue in. (See APSCO catalog page 23, No. 16201). Do the inserts come in different sizes?
