Thanks, John, for the helpful information. I appreciate it. On Jul 10, 2008, John Delacour wrote: > FIrst question : WHICH Schiedmayer? As I believe you figured out from the slotless bolts at the front corners of the plate, it is a S. Pianofortefabrik. >> Does it look as if the plank has been replaced by the previous >> repairer? I sure thought so, until I found out from you that there is apparently an inaccessible captured nut attached to the bottom of the slotless bolts. If the plate was out for pinblock fitting, I'm not sure how they would have reinstalled the bolts. I thought that the pinblock was a replacement because the fit is extremely poor to the plate flange, and to the sides, and the block is not glued in, and the pinblock screws protrude through the block oddly, and the bottoms of many the holes in the block were blown out by what looks to be careless drilling. None of these seemed consistent with the otherwise fine quality of the design and manufacture of the instrument. Oh, and the wood looks fairly new, and is 13-14 ply (one extra ply in the raised bass section of the pinfield, matching the bottom of the plate). I guess I'll find out once the plate is out.... > Once you have the frame and the plank out, it should become quite > clear how the piano was originally constructed, and I'd rebuild it > as it was meant to be originally. That's what I'll do, after cutting slots and backing out the bolts, or machining off the heads, as you suggested. > For the bass scale there is no problem; this can be brought within > proper tolerances and will also sound better.

Very kind offer, John. I will assemble that info and email it to you off list this weekend. Thanks again, Joe DeFazio (another JD)
