Paul said: "I used large washers in the back, but found the wood still crushed fairly considerably. It occurred to me at the time that I may want to glue on a 1/4" strip of maple or a hardwood plywood next time. Thoughts? Paul, On a few 3/4 plate pianos, with that malady, I've installed a 1/4" steel plate on the back to make sure that there was something substantial to anchor the bolts to and add support to the "free-floating pinblock". Works really well. I make the plate, (or, rather, I have my metal working/welder friend make), full width and the width of the pinblock area. That way I've got the thing screwed to the back of the piano and then drill through for the carriage bolts. Once that's done, I enlarge the holes in the metal to accomodate the square part of the carriage bolts. The metal plate gets painted black to match the back assembly. It works well for me. YMMV Oh, I use thick Fender Washers or recycled plate washers in the front. I also add more bolts than the original screw pattern to get an even bolt/support pattern. Joe Joe Garrett, R.P.T.
