The jumping is so bad I don't think it will be very difficult to tune.  I've tried reaming, naptha, sanding sealer and 3/0 pins with small to no improvement resulting.   Bob E. Hull, RPT </BLOCKQUOTE> Bob Did you measure the pins that came out?  The 4/0 pins are obviously way to tight. That is why they are jumping, and have a torque that is way too tight with which to be able to tune. And you say even a 3/0 is not improving the problem. That would indicate that perhaps even that size is too tight. Try 2/0 pins, and see what happens. If they are "normal," and your torque is in the 60 - 80 range, then I would suspect the original pins were 1/0''s, and the pin block is still in good condition. If there is a 2/0 pin that feels too loose, you can always put in a 3/0. Wim </HTML>
