David I. ----- Original message ----------------------------------------> From: Sarah Fox <sarah@gendernet.org> To: Pianotech <pianotech@ptg.org> Received: Sat, 12 Jun 2004 22:51:17 -0400 Subject: Re: Pulley Keys Hi Terry, David, There's an article about the technique on the Onesti Piano web= site: http://www.onestipiano.com/pages/journalarticle.html This seems to be a relevant section: <<If there are keys with massive damage so that a gauge pin will= not center in the hole, the key can be placed in the keyframe= with neighbors to align properly while sitting on a snug fitting= paper punching of .015" or greater glued onto the bottom of that= key. 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. (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.= (8) Fill any fore/aft gaps with epoxy (using tape on the sides to= retain it). Would that work?
