If you're going to do the hammers, the knuckles/rollers are worn/flat/unshapely *and* you're having to repin the shank/flange bushings, I'd just replace the lot. In the longer run, the action and regulation will perform better as will the hammers/tone. The money not spent on repining etc can go towards new components I think of it in car terms ...if you're replacing the tyres, but not solving the suspension problem, you'll be back sooner or later, why solve both at once, for less money Mark Bolsius ---------- From: DChadPiano@AOL.COM To: pianotech@ptg.org Subject: Grand Knuckles Date: Mon, 22 Feb 1999 3:40 PM Hello all... I?m rejuvenating an action from a Knabe Baby Grand owned by very busy music teacher. There is no serial number visible due to recent refinishing but I estimate it to be built in the 1960s-70s. They have agreed to have a decent set of hammer replacements, key rebushing and I?m repining the hammer shanks to flanges. The knuckles have suffered especially within the center 3 octaves and my question is...is there any materials or procedures that are good for bolstering the uneven knuckle and maintain a good ?roll? and shape. I?ll admit that I dont perform this a lot and found no real application to semi-restore the shape with yarn, action cloth strips etc. I hate to stab at it without first finding any input. Any suggestions? I?m sure that replacement knuckles would be the answer but this is a music teacher and it always seems to be that they are maintaining on a budget. What?s new! Thank for any suggestions! David Chadwick RPT Las Vegas, NV
