This is a multi-part message in MIME format. ---------------------- multipart/alternative attachment Was this piano built by Samick? If so, my guess is that it was built circa 1994. There was a period in which there were plenty of pinning problems, = particularly in the hammer flanges and jacks. They would seize up (or = at least threaten to) a few at a time about every 10 days or so ... most = annoying. Lubricants really didn't work well for long. You may just = have to go for broke and repin all of the action centers. As for the irregularity of the regulation -- I'll let someone else = answer that question. There are people on this list who could give you = a much better answer than I can. Z!

The aftertouch of = this piano is very irregular and they=E2=80=99re some parts of the = keyboard that doesn't have any aftertouch... The first problem I found = was that the key bed was suspended only in 2 B. screws (the middle = screws were floating)... I solve this problem and I checked the key = leveling and it was ok (64 mm), white key depth was too depth (=E2=89=88 = 11mm, I use 10 mm), Hammer leveling were irregular but it was about 46 = mm and there wasn=E2=80=99t let off and I corrected it (=E2=89=88 2,5 = mm)... even after this there wasn=E2=80=99t aftertouch... and the bass = section was very heavy... the sound was irregular but I=E2=80=99ve seen = worst... I had to put some lubricant in hammer flange center pin because = the hammer movement was a little bit slow and heavy but I think this = hammer flange center pin is not good=E2=80=A6 Do some of you have any suggestion? =20 Thank you =20 Jos=C3=A9 Fernando Rocha ---------------------- multipart/alternative attachment An HTML attachment was scrubbed...
