Wally Brooks has Japanese made direct replacement parts for old S&S uprights that are superbly made, fit perfectly and are easy to work with. These are expensive parts but they do work. I am working on my second action with replacement parts. Some suggestions. If butts and levers are in good shape then replacing the flanges can go a long way to a functioning action. Remove all the parts except your samples. Check the pinning of then install the butts, keep them aligned at 90 degrees to the rail. Keep retightening the screws. Install new damper levers but keep the damper blocks. They are drilled at the exact angle needed to make them work best. If you need to replace any block make them from similar materials and drill the angle exactly to it's neighbors. If these blocks do not have metal inserts then install them. Install the damper levers, align the wires, install the blocks and install the new dampers. Be careful because there is little room for the operation of the damper levers between the spoons, action and the strings. Get the dampers working PERFECTLY, muting, timing, alignments, before installing the hammers. This is the most time consuming operation of them all. Adjust the spring tension of the new springs before installing the hammers. You travel the butts by rotating them around the screw. Shimming the flanges spaces the hammers. Figure that this action will cost you at least twice the time of a regular action. Lots of luck. Newton
