Hollow Mill Holder

I found a hollow mill in a box of tools I bought recently, but it doesn't fit in my milling maching. Since these seem to be a fairly unusual cutter, and I actually had a use for it, I figured making a holder for it would be a good excuse to show what it does. Hollow mills would have more commonly been used in screw machines to turn down the diameter of a bolt, but they work in the mill as well.

I promise I'll still mostly make stuff out of rusty junk and not just buy shiny things with your money.
