Hi Jim, > Well, at least you know you are not on my delete list. Certainly glad of that! : ) >If the loose > tuning pins of a vertical piano are all in one straight horizontal > row, I would suspect an internal split in the block. Didn't notice, but since this piano did not have plate bushing, the holes thru the plate are smaller, and I didn't find any to be rubbing against the holes, but I would want to take a second look. > In such case, PBR > will not solve the problem. and might mess up the situation if boat resin or epoxy has to be used. > >Neither will oversized pins.

Makes me want to get a hold of the ear doctor's otoscope. Hmm I wonder if vets use them, if so I know where I might borrow one. Seems like one might see the splitting if it is that bad. I will post the results if I can try this. >The next day, we would drill out the holes for 00 pins and > reinstall the pins and strings.

I have repaired a few of these, but don't remember loose pins also. But it seems like if it was pulling forward the laminations towards the bottom could be splitting. I'll check it out. I was thinking too that if laminations are splitting, I could put a small becket on a piano wire and drag it thru the hole. If it catches it might indicate a separation. And now that I think about the way the s b is split, I shouldn't be surprised to see the same condition in the pb. I have never had a "split" block before. Thanks for the reply. Nice to see a little humor is tolerated even if it fails the 'push the send button test'. Richard Moody ..
