I recently delivered an old 1884 Chickering which was restrung for a customer. The 2/0 pins were not loose but once apart the block was slightly delaminating. Since it was a fitted-front-and-rear-with-angled top I didn't want to replace. I swabbed the holes and outside with 301, then mixed in some collodial silica and swabbed again forcing it into the thin cracks. Then I clamped them up to dry. I reamed the holes on a drill press ala Ron's two bit method. I used the Low-torque pins from Pianotek (4/0). The piano tunes fine. it feels like a new block. I might swab the holes on another block that will be getting oversize pins. Regards, Jon Page At 04:56 PM 7/27/2002 -0700, you wrote: >I've done it several times. Works fine.
