Thanks, John. I could have used that today, I broke a 0.050" bit in cast iron, about 1/4" down on the second peck by mouse control, & another .3" to go. I wound up moving the hole, but not quite far enough & dinged up a 1/4-28 tap on the remains. Using a properly programmed peck cycle, I imagine I can do the next one just fine by following that advice. I was installing a grease fitting, and that was the channel into the bearing bore. I got all the parts to put ball bearing thrust washers in the screw bearings of my micromill today, so I ran out and put in the first pair. Sweet! No more squalling screws & the backlash is now .0004"! I can't wait to get the other axis done, but this cold rain ran me out of the shop till it warms a bit again. -- Cheers, Gene "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
