<HTML><FONT FACE=arial,helvetica><FONT SIZE=3 FAMILY="FIXED" FACE="Courier New" LANG="0">I am restringing an old upright, open face pinblock, with 4/0 pins and encountering jumping and creaking in the pins.  Torque is coming out to be anywhere from 100, 140 and 160.  Several of the holes may have been doped as they have a black half circle, top side of hole, about 3/8 inch deep. 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.  <BR> Bob E.
