A table-mount drill press on the keybed with a Forstner bit removed most of the stock and a chisel cleaned up the perimeter. I left about 1/8" of block on the bottom. The inlays were carefully fitted for 'no play' and epoxied in with Epoxy Tech 301. After that shrank, a thicker epoxy was added to the edges and repeated until full. The flange had MarineTex epoxy applied and the plate fit in. A new pin pattern was laid out on tracing paper and transferred to the block. I drilled the holes before installing the inlays. I did not drill all the way through the block in order to prevent the epoxy from filling the holes from the bottom. While I had the thin epoxy working, I reglued the square'd corners of the case at the bass and treble. Five years prior another "rebuilder" had plugged the block. Unfortunately he did not tend to the splits between the holes and the plugs caused the cracks to expand... The sound board had large areas loose from the ribs which the customer didn't have the money to replace. I devised the Sound Board Press which employs wooden I-beams clamped to the rim with pipe clamps and spring-loaded plungers to apply pressure for reglueing the ribs, the board was supported from the bottom; jpg's available. A fun project.
