The sides of my M&H popped off reasonably easily with three small/medium old chisels. I don't think there was one square inch of glue joint that gave way. Most separation occurred between the side cores and the two inner facing veneer laminations. A few spots of frame broke out, and a few good chunks of side core broke away. The hide glue joint did not fail. So what difference would it make if you used white glue (Titebond)? For that matter, why not epoxy? I like the idea of the saw. I might try that next time - just to get a nice even predictable surface. As for using the irregular break out of the torn wood for indexing, that might work for placement, but I have never been able to take an assembly like this apart with significant wood tear-out and been able to put it back together and achieve the same dimensions. I have found that the wood will never go back together as well as it came apart. You look at it and think it should, but that would require that all break-out occurred with sides either being square or obtuse. But I suspect there are plenty of irregular wood chunks broken out at acute angles, thus preventing good re-assembly. Or am I missing something?

A skill saw?? The sides are attached with hide glue..as a rule. A few well placed "hits" with a heavy hammer, and the aid of a chisel, does the job perfectly...particularly if the sides come off with a few chunks of the frame. These are the only accurate "indexing holes"! Simply align the "chunks with the "divots"....no need for measurements..shimming..dowels etc. Then reglue with hide glue. That is for the next guy. Lord help him if you used white glue....or the increasing popular (shudder) CA stuff. Regards, Bob Been there, did it the wrong way, learned the right way, now IT'S here to stay!

The piano had been put into the basement of this house before the main floor and the staircase were built! With VERY accurate measurements, I determined that the back would indeed fit, diagonally up the stairs. But nothing else! So, the piano had to be completely taken apart, right down to the strung back! I removed the sides with a 10" Porter-Cable (Skill type) saw. It is a really heavy/beefy honker with torque to spare. The 10" blade was set at maximum depth, which was about 1/4" to 1/2" shy of going all the way through to the plate. I put the piano on it's face and had at it! (Yes, I had help with this project....my son. <G>) Once we got the piano out of the basement, (the best local mover and his helpers did the move up the stairs.), we loaded the whole "piano kit" in the trailer and the suburban and headed for the shop. The one mistake I made, was that I did not predrill some indexing holes, so it was a little more difficult to get everything back and aligned. Because the 10" saw blade made an 1/8" kerf, it was easy to put 1/8" maple plywood in as spacers to compensate and get the original "width" back to what it was. The piano was saved for the "Son" & his wife, by doing this. The Mom and Dad were delighted to get the piano out of the downstairs Rec room. Happy ending to a real project.
