A Small Endmill (1/16")

 Last evening, I tried out the old way of making an inlet inscription on a small aluminum ring I quickly fashioned on the mill. Basically, when nice tapered, carbide end mills were hard to find and make, small end mills were used to cut the entire profile of an inscription.

I found keeping track of my location in thousandths of an inch hard to remember and messed up on the last letter. I learned a bit about small size tooling and some of the CNC "do one" functions on the Proto-Trak systems mill.
