We have a Colombo spindle, how much do you want for them?

[knight_toolworks]

how about 15 each and shipping? I have two more of the shiny ones if I could find them and another black I think. of course I put them away and can't remember where.

I bought a couple collets and nuts, No-Names from Ebay. Ruined two good bits. If you get them there make sure to use a name brand. The extra $40 would have saved me $120 worth of bits. (and the trashed projects)
