I
traded something for this Enco full size mill that was headed to the
scrapyard- the knee was stuck, which sometimes happens when the knee
gib riding on the column either breaks, gets gummed up, jammed with
some chips, or something happens where the adjustment screw engages it.
I figured I'd probably just be able to save the head as they
were not able to free it If this ever happens you need to stop
and go very carefully to ensure that the gib goes up and the knee goes
down, or the gib stays put and the knee goes down so not to make the
problem worse, which is what happened before I got this. You can
drill thru the base and try to tap the gib up, slide something up to
the gib from below so it is held in place while you try to move the
knee down or force it down with some force applied between the
underside of the dovetail ram and table, etc. I tried all of
these and was able to see that there was no hope, and there were hammer
marks on both the top and underside of the knee where they had tried to
free it. I figured since this would otherwise be scrap there was
one alternative- cut thru the casting at the rear so a could spread the
ways just a few thousandths to free the knee. I rigged a
reciprocating saw to a long piece of bandsaw blade that I punched holes
in, one end attached to a spring thru a screw eye on a board, put some
tension on the spring, clamped the saw above the knee, with enough
tension on the spring to keep it taut and fired up the saw. Took
a while, but eventually sawed thru the casting, tapped a wedge into the
saw kerf and the knee slid right off. I ordered a new gib, milled &
ground it to fit, I then drilled 5/8 holes thru the knee from
left to right near the top and bottom as close to the ways at the back
as I could, put grade 8 fine thread threaded rod thru the holes with
flanged nuts on the inside and outside of the casting on each side, ran
the inner nuts hand tight to the inside of the casting, then torqued
the outer nuts and repeated until I was able to get within the proper
range of adjustment for the gib installation. Although not as
stiff as it was, this machine is still making parts and was saved from
scrap. Presumably with the rods in place someone more skilled than I
might be able to weld or braze where I cut, but that would have
been a whole new can of worms and risk. Sorry I forgot to take
pictures of the rods installed.

cool how the guards all pivot out of the way and the overhead light moves to the side so you can use the whole disk area
started out ugly, before and after. Another one left outside a few years before I got it.

Roll
up disappearing spray booth, velcro corners. The walls have
conduit at the bottom and roll up as they are raised on pulleys with
cord. Initially the fan pulled thru the filters in the door, next
time I'll be using a blower that pulls air thru a filter and
pressurizes the booth instead- the walls would bow in slightly in suck
mode, but it worked. Miata had a front hit & I replaced front clip
core support and inner fender, etc.
Welding
rack, everything in the least amount of floor space possible, storage
above. Looks tippier than it is, but its always on smooth
concrete mig, tig, plasma, & oxy-acet.
