Alan, When I did this operation to a similar set I followed exactly the steps you have outlined with one exception. I made a simple jig which allowed me to make a precise cut to the new dimension with a razor saw. The little bit of waste left over chipped right out (usually flush to the bottom of the mortise) with a little bit of pressure from a sharp chisel. Any left-over wood cleaned out very easily with the chisel. This method is very precise and quiet. You can listen to music while you work instead of the sound of 1,000 killer bees looking to chew on your fingers. I seem to remember the whole process took about 4-6 hours including removal, cutting and replacement. It takes a bit longer than cutting off the old knuckles but then you don't have the expense of the new knuckles or new router bits or blades... ``````````````````````````````````` Eric Wolfley Head Piano Technician College-Conservatory of Music University of Cincinnati ```````````````````````````````````` -----Original Message----- From: Alan McCoy [mailto:amccoy@mail.ewu.edu] Sent: Monday, July 19, 2004 7:53 PM To: CAUTlist Subject: Moving knuckles Hi folks, I have a situation here where instead of replacing shanks, I am going to use the not-so-old shanks and move the knuckles out to 17mm. The knuckles are really not all that worn so instead of band sawing them off I am thinking of just pulling them off and moving them (if that diameter will work in the new position). Then I'll glue in a piece of hardwood to fill the old slot and cut a new slot. I'm thinking that I'd prefer routing out the new slot but I'd like to hear some thoughts from others who have done this operation before. Thanks.
