Spent a couple of hours with my almost civil war patented horizontal
mill yesterday. Somebody has to take it apart, just seems like it is
always me that has to do this kind of stuff. The gib screws are .6" X
2" with single slots that are wallowed to the point of looking like
snow angle's wings. I got 4 out of 10 out and pounded on them with a
3/16" flat round ended punch counter clock wise.

When I started typing I thought of welding a tire iron slotted end...
don't have 6 of them. I really don't want to have welding marks on the
machine cause I can never see well enough. Nuts may work, but will be
worried that I'll weld the screws to the machine, the way I weld !

I use to have to get allen screws out of crankshafts and am pretty
good with drills and easy outs. Never did fail on a crank. But, having
trouble foreseeing a drill bit against a slot wallowed bigger on each
side than the middle. Couldn't remember if HHS shatters like carbide,
that didn't take long. The fast and dirty chisel cut a couple of times
till it shattered.

Got some funny dressed drill bit/mill bits from Mr. GD that I'm not
sure what they are for. 90 degree step so I guess putting counter
sinks with. Couldn't find them just a second ago, but know they are
there. *Maybe those and then to a real HHS american made step drill?
The step bit won't do it alone. Or maybe dressing a chosen drill bit
to looking like a large pencil point? I don't own any small metal
chisels and don't want to destroy a punch, but that might work, to
chisel the remaining sides to drill without total chaos.

I read all the recent posst about auto stuck studs, what else is
missing. I can borrow a die grinder, but don't have a sharp bit.

Kinda sounds like a job for one of the manual hammer type impact
drivers. Soak the problem screws in with Kroil for a few days and then a
good whack with the impact driver will probably get them out since they
are likely not stuck too bad if you got the others out.

Anyone who has used one of these back when motorcycle case screws were
soft *phillips head* can attest to the magic of which those hammer-
driven impact drivers are capable.
