Hi Bill, Good to se you again so soon. I would tighten the plate screws in the middle section then use a pinblock jack to put pressure on the block and see if you can get the screws to move again. It may well be the block and plate are mated together under the webbing of the plate but they may not be. I had a S&S D once that had this problem and it would NOT stay in tune long. Tightened the screws and it was much more stable. Care must be taken and a lot of thought given to the possibility of the plate cracking. Also, if it ain't broke don' fixit. Newton
