Ok, I've been playing with ,y Taig mini mill for a while now and I have some
idea of its limitations. I'm not quite ready to buy a lathe yet, but I'm
working on it. In the mean time I thought I might be able to make some
small parts if I could find a lathe style chuck to fit my mill.

It uses ER-16 collets so I was thinking, "just find a chuck with a 3/8
shaft, and use my 3/8 collet" There are a number of small inexpensive
chucks out there, but they all have a tapered shaft. At least all the ones
I can find.

For example

If I had a lathe I could turn that shaft down to fit one of my collets, but
I'm not sure how to do that with my mill.
