There is a difficult part in having the good wood washers that have a = good fit vs the machined emplacement. in the time I expressed I did not count the wood washer drilling, that = is not very fast work (1 hour or even more may be to make a set) Tobne wood for violins is good for the washers but one have to know = the producer or the cost will be too high.

This will provide an = adequate guide for the pin and cutter. Selecting the proper drill bit = for the size of the balance pins, insert it into the plug cutter, = centering properly.>> The following technique might be used to *establish* the correct = alignment for the "snug fitting paper punching": (1) Put a snugly fitting paper punching over the balance rail pin. (2) Put a tiny dab of glue on the punching. (3) Carefully lower the key onto the punching, making sure to position = it correctly with respect to its neighbors. (4) Leave key until glue is dry. (5) Remove key and mark/measure the position of the punching hole = (perhaps by making a mark exactly X-distance "aft" of the correct = position). (6) Cut the notch, glue in new material, etc., etc. -- placing the = balance rail pin hole at the previously measured location. Or here's another idea: (1) Cut a notch in the key. =20 (2) Cut an insert to go in the notch, leaving just a tiny bit of room = for fore/aft "wiggle," and leaving just a tiny bit of excess width (not = so much as to touch neighboring key). (3) Drill a balance rail pin hole in the insert in the "best guess" = location. (4) Dry-assemble the insert and notched key on the keyframe and check = for alignment. Needs tweaking? Remove material from appropriate end of = insert to achieve correct alignment. The point is that it should be = *possible* to align the keystick over the insert, when sliding it = around. (5) Remove keystick. Leave insert on balance rail pin. (6) Put Titebond on both surfaces. Lower keystick onto insert. Align = correctly with neighbors. Let dry. Perhaps epoxy would be a better, = albeit messier, glue for this step, since clamping the joint (e.g. with = weight) while maintaining alignment might be problematic. (7) Remove keystick/insert. Shape the insert flush with the key. =20 (8) Fill any fore/aft gaps with epoxy (using tape on the sides to = retain it). Would that work?
