Question (based on zero experience in this procedure): When you have do all that, wouldn't it be easier, faster, and cheaper just to start with a new piece of lumber?

Wow Ed, indeed, a weak moment! Good to see you are tough enough for it though!

Pinblock. I assume the plate is out of the piano (how else did you remove the soundboard?). Plug the block with plugs cut from pinblock material of your choice. Webb Phillips sells Delignit and maple multi-lam 1/2-inch and 3/8-inch plugs. Some people drill the same size hole, use Tightbond and pound them in. I drill an oversize hole and epoxy them in place with West System. Make heap strong pinblock. Pinblock look like crap, but get real solid - just like new (or in this case, likely better). If you want the full story of all my trials and tribulations on using epoxy in such a case, just holler. Picture of epoxied-in pinblock plugs (square grand).
