I assume you have a workbench/system which allows you to duplicate the topography of the keybed? Yes I do. I set up my bench with guide rails up front similar to what the Baldwin Grands have. I then set the first and last hammer of each section in the piano. When I put the piano on the bench (which has already been adjust to the action), I adjust my let-off rack, then fill in the blanks. I also use my key leveling weights on the base of the rack for stability. Once back in the piano, you can check and make any minor adjustments that need to be made. It is very close.
