Dear Carol: It was my distinct impression that the greatest cause for the loosy goosey tuning pins in the bottom few pins is that during the rubbing down of the case, the lubricant used seeps into the pinblock and eventually causes this symtom. Soap is used on other plate screws which are just as close to the pins and does not seem to bother their holding ability. If factories would completely mask off the block while rubbing down the case, this problem should be terminated. Jim Coleman, Sr.
