Keith, You're right, the Knuckle Buster is the way to go. I find that it works far better though with a little auxiliary table that I made for the drill press table. It's a simple enough affair to hold the shank in the same position each time and brace the front so the knuckle buster can shear off the old knuckle. All in all this makes a clean, neat job. When installing new knuckles, a small concave caul with a shank chucked in the drill press chuck (with the press turned off of course <grin>) is wonderful for pressing the new knuckle straight into the kerf.

The best tool I have used thus far is one made by Glen Hart of Hart's Piano Shop in Colorado, USA. It's called the Hart Knuckle Buster. Much safer then the razor blade. Very effective. 970-434-5558 hartpiano@aol.com Good luck, Keith McGavern Registered Piano Technician Oklahoma Chapter 731 Piano Technicians Guild USA
