W.E.T. [CAD_CAM_EDM_DRO] Re: linear bearing based on ground flat stock

Hi Graham and All:
Why bother to take the table off the mill? Why not just use the
vise with a tool holder mounted in it out the side of the vise. I
have a four jaw chuck for my Sherline mill so I can use the mills CNC
for chucker work as I do not have a CNC lathe. If you face one side
bore the hole, and turn the OD groove in one chucking then everything
will be dead true as good as the bearings in the spindle. Just my
way of thinking and doing the job.
GOD'S BLESSINGS

My feeling is that a roller based system will offer less resistance to
my little belt drives than a bush based system. Some square bar with
4 flats on the bottom should not offer too much trouble. I'm not much
of a lathe man so I'm not so sure about making accurate v-rollers but
I think it will be a good learning experience. I'm actually tempted
to take the bed off the proxxon (its only held with 4 bolts) attach a
lathe tool to it and automate the cutting of the V's, that probably is
just gee-wiz talking.

I've found some nice flanged bearings of 5X8X2.5mm which might do the
trick and I've asked for a quote on the smallest rollers from the guys
linked to earlier as another option.
