I have an opportunity to purchase a milling machine that is within my
budget
and will possibly with a little sweat equity be a decent machine for my
"out
of control" hobby shop.The machine has Meehanite castings, DRO and X
axis
power feed as well as a one shot lub system


How would one go about repairing a three inch diameter cutter mark that
is
in the center of a 9X42 offshore mill table that is .050 deep.

If it was mine, and it bothered me enough, I'd bore it deeper, then plug
it
with a quality piece of cast iron, then refinish the surface *very*
carefully. That wouldn't work if it breaks into the T slots. Or live
with it.


This machine also has .30 backlash on the X axis. Any tricks to repair
or
improve this?

That is a non-issue. Machine tools have backlash----it's a fact of
life
(unless they have ball screws). You learn to use the machines,
regardless
of the amount. It's what separates a machinist from a wannabe.
Besides, .030" is hardly backlash. New machines often have that much.

Um, Harold? He said 3/10". Most new machines don't have that much (some
Chinkalloy junk, maybe) G.

Blush! Yep, that was .3", wasn't it.

Ok, I retract my comment about backlash. That's one hell of a lot-----but
I'm having a hard time understanding how a dial can have more than one turn
of backlash-------which is greater than the lead.
