But, what is wrong with the old fashioned way. Fit the block to the plate, and bore all of the screw holes, insert screws, and then with a center punch, mark all of the pin holes. Remove block, and transfer to a good drill press with a 750 RPM setting, with a backing as long as the block, and set at a 5 or 7 degree reverse angle. Much easier, cheaper, and just as accurate than building a complex apparatus to sit on the piano, which in most cases would probably gouge the case. Just my thoughts on it. I have done dozens of grand pin block replacements using this method, and none has ever failed.
