I thought about that but at the moment my only CNC mill is the tiny
Proxxon, max capacity of the spindle being 1/8".

But I could do what you suggest if I made a mandrel of some sort I
guess, definately one to consider!!

Just out of interest if I wanted to do some g-code for the v, other
than hand coding or excel spread sheeting it are there any FREE pieces
of software out there that can produce the toolpath? I'm thinking
somewhat generally not just for this job.

I also got some prices from superior bearing for there smallest
rollers that seemed very reasonable so there is still the chance I
will go that way.
