<HTML>Hi List, I was going to list this as "Today's Puzzler," only that wouldn't be fai= r, because I don't have an answer yet...:-(  Hopefully, with a little m= ore tweaking, and some good advice from this great resource, I can come up w= ith one. A friend of mine bought a 70's Baldwin Hamilton Studio from a local deal= er.  I went out to do the free tuning/service call, and found that the = piano had basically not been seviced at all in the shop.  It was a quic= k in-and-out deal.  The piano was filthy inside, really out of tune, ha= d plenty of lost motion, and had lots of action noise.  After a bit of = regulating and a tuning, the piano sounded and played much better--except fo= r the clacks. This is a corfam era piano, but I know that sound: this is not it. &nbsp= ;What I'm hearing is almost like a jack or hammer shank slapping on somethin= g.  I think I've got it isolated to the whippen.  Last night I too= k the action out and tightened every action screw in sight(and some hidden o= nes).  They were definitely on the loose side.  Put the action bac= k in, and the clacking/clicking was still there. If I had much hair left, I'd be pulling it out by now...any suggestions = as to what this might be would be extremely helpful.  I guess I'm a Bal= d-whiner. This comes a day after tuning a 90's Baldwin that has hammers that make = granite seem soft where I couldn't get a clean unison on isolated single str= ings in the temperament....:-} Thanks in advance, Dave Stahl</HTML>
