Daivd: In almost all cases, on the Steinway blocks, the long cuts are so close to straight that I just clamp the new pinblock blank to a table, duplicate the full fit shape of the old block (Bolduc router method for removal of intact block) with a pencil line, and on the flange side move that pencil line in about 1/8" to account for the flange angle including the notch, then set up my circular saw to match the flange angle from the old block using an angle gauge, cut the straight lines, then trim out the notch with a jig saw also set for the angle. This gives me a good rough cut block. On B's etc., the curved notch is also cut with the jigsaw. Altogether with removal it takes me about an hour to get the rough cut block. Much to do then since I hand fit the block with a power rasp. But the new block is very close to fully fitted at this point, and I do the same thing that Ron does with the stretcher edge--a slight bevel to take a wedge filler with epoxy. I dowel the ends into the rim but not the stretcher. Waiting for more data.

Steinway blocks are relatively easy and I do it simply by double sticking the old block to the new one, matching the flange angle with the adjust table on my band saw and rough cutting the overall outline, have at it with a power planer, grinder and sander and use epoxy with high density filler for the final fit. Easy on a S&S S,M,L, O, A, not as easy on a B where the bass/tenor transition is curved Anyway, I’d be curious to know how others do it—especially that bass/tenor transition area—that is, short of having one of those super duper fancy contour duplicating machines.
