Using a small three cornered file, cut two light relief grooves lengthwise and opposite each other in the in– side diameter ~f the cap opening. The grooves should not exceed .015 inches in depth. If the grooves are cut too deeply, a pounding action will result each time the Clamp Table is sent bock because the cushion of oil, between the Sleeve and the Cap, will dissipate too quickly.
