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.
