Hi: threading is not a misto. If possible obtain a ball with the same pitch as the acme that it is replacing. If this is
impossible, then look to the spud gears between the spindle and lead screw. In most small lathes there is a quadrant swing so you
can fit that, that will work. good luck. jwh HTD San Ysidro CA.
