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
