Hi Dale, Better than spending a day repinning....vodka has worked for me, too. Were these the ABS flanges, or were they wood? Thanks, Dave Dave Stahl, RPT Dave Stahl Piano Service dstahlpiano at sbcglobal.net dstahlpiano.net -----Original Message----- From: erwinspiano at aol.com To: pianotech at ptg.org Sent: Thu, Jan 14, 2010 6:11 am Subject: [pianotech] Follow up on UST-7 pinning issues Hi Dave. Yes I agree that they are good instituional piano. We disconnected all the bridles to remove the wips from the equation,tested to see which ones were really stiff. 90% were. Jacob & I sized all the flange bushings with a 3 parts alcohol to one part water. We re- pinned only a few of the tightest then put the actions in the hot box for 3 hrs at 80 degress 30% r.h. I can now push on the backcheck to engage the butt, move it thru let-off and they are now free enough for the springs to push them back toward the checks. No loose pinning. total time was about 2 hrs apiece. Customer is happy Just thought you'd like to know.
