The first thing = I noticed, and the thing the customer complained about, was an extremely = heavy action. This was because there was a lot of let off, about 1/2". When = I removed the fall board, I noticed that the pin block (which had been replaced), was sticking down from the front stretcher about = 1/4".  My first inclination was that the plate was set back in the piano too = high, and that is why there was so much let off.  I have replaced = the pin block, and the plate is back in the right position, and there is good downbearing. But I am now starting to work on the action, replacing = the h/s/f and wips. Now I see why there was so much let off. This other = rebuilder used a 1 1/2" thick pin block. But instead of planing down the entire block, = he only trimmed down the ends, which rest on the inner rim, but he left rest = of the pin block the original 1 1/2". That is why there is about a 1/4" of = pin block sticking down below the stretcher. Obviously that wouldn't allow the = action to slide in. So in order to get the action in, he lowered the action by = shaving down the action frame mounting blocks. (I think that is what they are = called). I want to replace the blocks. But the question I have is = measurements. About 20 years ago when I put a new action in a Steinway, and these = blocks were not attached to the action frame. I think I remember I had to = sort of go by where the striking point was of the last couple of notes, combined = with the hieght of the hammers. I had a hell of time figuring out where to put = them. Is there some measurement I can go by to determine where I have to put = the blocks, and how high the action has to be? Wim </BLOCKQUOTE></BODY></HTML>
