I had an old Fischer grand where the keys were so bad that the front line of the ivory overhangs looked ragged when viewed from above. There was substantial (1/32" or more) side to side play as well as the worst front to back play that I've ever experienced. The keys needed rebushing anyway, so I treated the balance holes to a liberal blast of steam from a tea kettle, say about 10-15 seconds each, followed by a generous slathering of thinned hide glue and to my amazement the problem disappeared completely and hasn't returned in the ten years since. The glue sizing mixture was actually nothing more than the water from the jacket around my glue pot, where I dip the brush between uses to keep it clean. It was basically just hot water with a very small amount of glue in it. Just enough glue so that it would produce a gel when cooled. - Mark -----Original Message----- From: David Love [mailto:davidlovepianos@earthlink.net] Sent: Thursday, June 10, 2004 8:33 PM To: Pianotech Subject: Pulley Keys Anybody want to share favorite methods for fixing pulley keys?
