<!doctype html public "-//w3c//dtd html 4.0 transitional//en"> <html> <body bgcolor="#FFFFFF"> Hi, I agree with Brian. It is time to view the top of the pin block. You might have to remove the top. It may be glued on, with or without screws. I have 4      8" C clamps that I use to pull the block, back into position. Sometimes, I don't even have to lower the tension. I then remove the screws, or lag bolts, one at a time and drill out the hole to accept a carriage bolt.   3/8" is apparently all that is needed, although larger can be used, if it gives you a more secure feeling. Acorn nuts could be used to give a more 'finished' look Make sure no wood chips get in the seperation, before you glue and close the seperation. Check for loose or cracked bridges, and cracks in the soundboard. This probelem is normally caused by an extremely dry environment. It could have loose pins as well. Regards, John M.

I hope I can explain this clearly, I'd raise it above where it needed to be  for example  if it was 75 cents flat and I raised it over maybe 20 cent next tme it would be 40 cents flat and it would take 4 or 5 time going over it to make it stay and the last two octaves  would drop off the where their not any lights at all {SAT] 3 -4 times and the pins were not too tight nor that loose, It did have miner damage to the corner bottom of the case and some to the bottom on the back but no thing I could see inside and it finally held  Pat  assoc.</blockquote> </blockquote> </body> </html>
