As some may recall... I did rebuild a 1890's Knabe upright. Yes, the plate could only come out after removing the bass area of the block. The flange was too tight untill that was done. The SB ( not SOB) litterally fell apart when the plate came out. Installed new SB and bass block. I cannot trust old glue joints when it is put into full time service. Reamed the rest of the block to accommodate 2/0 X 21/4 pins. (Originals were #1X 2"). With mostly new action parts and new hammers it sounds and plays great. I still have the piano and will give it away soon to Project Liberty Ship..

The cabinet was built around the case on a lot of those. The low tenor is often a problem, grain run out on the bridge there is common (ESPECIALLY on Knabes) and I've seen bridge roll and a loss of bearing in that area. It's not really a recording piano, more money than it's worth to do right. Might have to live with it, Daniel.

Anyway, if you like the sound and it's not buzzing, just let it be. No, you can't shim from underneath, you would need to de-string remove the plate and shim the cracks. A lot of work, especially for an upright. Then again, if it starts to buzz, then off to work you go if you think it's worth it!
