I think plugging and re-drilling is the way to go as well. The slight angle is the factor. ----- Original Message ----- From: "Greg Newell" <gnewell at ameritech.net> To: "'David Ilvedson'" <ilvey at sbcglobal.net>; <pianotech at ptg.org> Sent: Wednesday, January 27, 2010 4:50 AM Subject: Re: [pianotech] Chickering Pedal Lyre You can't use this method where the screw is drilled in at an angle. The best and easiest solution is to plug and redrill. Use pin block material for a lasting repair.

I will remove a little keybed material, ala bowl shaped so the female is pull down into the keybed. You will need a bunch of lengths...I can't remember the size I use. ...maybe 5/16. Have lots of washers so you don't have the bolt coming up above the keybed.
