If you go with a machine tool, get a lathe to start. You can jig stuff up and mill with a lathe, but you cannot turn with a mill.

There are 3 kinds of people in this world.
The wise, learn from the mistakes of others.
The smart, learn from their own mistakes.
The others, well......they just never learn.
