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

John,

   Interesting thread, especially KAwhoom-FLAP!, but scrolling up 
down several times didn't reveal anything I could recognise as an
article or link thereto. Is the chat in the thread the article, or did
I blink?

   It seemed a good deal more flamboyant than recent informative
description of experience with hard and soft aluminium, on this list, I
thought.

Erik
