Loosening the endpin

[Brian Gencarelli]

I would give the endpin rod a coating of wax. (Sometimes cork grease like clarinets use works well.) I use the Butcher's bowling alley wax. This won't affect the ability of the screw to stop the pin, just the ease of the pin sliding past the swollen cork.

Don't slather it on, and make sure the product doesn't contain silicone. Wipe off excess with your fingers and it should work well.

YMMV
