The piano had = recently been shipped out here to California from South Dakota. When I = tried to pull the action it got hung up on something on the bass end. = Upon examination I found that the drop screws in the last octave where = scraping against the bottom of the pinblock. I was able to reach down = with a long screwdriver and lower the screws enough to allow the action = to come out. I could then see that the extreme left side of the pinblock = had moved downward in that area by about 1/16" or so, just enough to = take up the usual gap between the screws and the bottom of the pinblock. = There didn't seem to be any delamination in the layers of the block, and = this also seemed to be a recent condition, as the scrape marks from my = first attempts to remove the action were fresh and apparently the only = ones that had been made. Someone in the past had replaced some hammers = in the bass section, so I know that the action had been removed before. = I tightened up the plate bolts in that region, which had no affect. = Anyone ever had this problem, and do you have a good fix? I am thinking = of using a pinblock support to try to press the low section back in = place, and then retightening the plate bolts. If that doesn't work, then = what? Use a grinder to remove the excess material? And what could have = caused this to happen anyway? Thanks,=20 Patrick C.
