RE: [CAD_CAM_EDM_DRO] loose quil

I would hard chrome plate it but it would need to be reground after
chroming so it could be expensive to chrome and grind it.

Dave: I had a nearly-similar quandary on a Chineesan drill, and I
dismantled
the head to get the casting in my hands, and then sawed a "slit" up the
nose
partway, through to the hole the quill resides in, and then I
drilled/tapped
for some CR bars I screwed to the front of the nose so I could "clamp"
the
quill fast up or down (this little DP had no "little handle" to clamp
the
quill in Z-movement). This only squeezed the cast-iron "nose" a few
thou.,
but enough to clamp the quill. Thus, surely if a screw or two were
installed
horizontally through those two bars screwed to the nose, either side of
that
slit, you could "make up" the gap to a tenth, as you tested for
free-movement, as you tightened. You might even use longer screws,
putting
lock-nuts on the excess, to tighten against the left bar, etc.

Of course, you could also bore-out the cast-iron and install a brass
sleeve,
and...

Lotsa luck! Jan Rowland
