      Exactly right! Box ways can be replaced but factory "V" ways can't be.

      Why would someone not do this with a regular lathe (as you mentioned)?  Are the grinding byproducts destructive to the ways and gibbs?  I would imagine they would accelerate wear, and would be hard to prevent from getting into everything, as fine as it is...

      Hi Costas
      My camera died so no pics for a while but the setup is simple. I used
      a Volvo front disk that has a hub. I just chucked up the hub, cut the
      disk smooth and glued on an antique 9" sanding disc. I mounted an
      angle plate and an old milling vise on the crossfeed. The "grinder"
      took a few minutes to make and took just junk box stuff, lining up the
      vise etc. took much longer.
      Why was this project worth even mentioning? The results were amazing!
      I thought of why:
      The disk was rigid and balanced.
      The vise was rigid and could be fed .001" at a time.
      I am not sure if the sanding disk was dangerously over sped or not
      since the disk was glued on but the setup accurately ate very tough steel.
      Taper pins would sure make aligning faster!

      Pat
