The jack springs are held by thread loops (at least = on=20 the squares I tangled with) and though most are amazingly intact, now = and=20 then one has broken. Not hard to replace (I used silk cord) except that=20 getting access to the part is hard. I did replace a hammer shank on a=20 square once, for a lady who was retiring and wanted to play. She had a=20 photo from 100 years before, of some fairly rough-looking male relatives = standing in front of her piano, from the 1880's. I needed a 3/16" shank, = but longer than a spinet shank. I had to get a 3/16" dowel from the=20 hardware store." 1. Vellum is redily available from Fletcher Newman, U.K. 2. Use fly casting "backing" line or woven casting line. Available from = your local sporting goods store. Access to the spring, etc. is = accomplished by removing the key, (which can be done w/o removing the = stack, BTW!). Remove the rocker capstan. drill out the "plug", that = holds the string in the jack. Insert the casting line into the spring = loop, double over and insert into the hole in the jack. Use a round = wooden toothpick and a dab of cold hide glue. This will be a "force = fit". The trick is to get the spring to START to engage, when the jack = is a a 45 degree angle to the key top/rocker capstan top surface. If it = engages earlier, the spring tension will be too strong and repetition, = (such as it is), will be greatly compromised. If it engages "late", the = jack will not have sufficient "force" to seat under the butt and the = darned thing will "cheat"! Also, when re-installing the key adjust the = lost motion as it would be in a spinet. Lost Motion is needed! (Just a = "wink" is sufficient.) 3. Square grand, 3/16" hammer shanks are redily available from Schaff! = However, they are labled "Reed Organ Pallet Rods"! These are longer than = spinet shanks, but of the same stock. Warning: There will be loads of = "rejects" so order at least 100, if you are doing misc. = replacements......1000 if you are re-hammering/shanking an entire = action!!! Regards, Joe Garrett, R.P.T.
