I own a mini mill and a mini lathe. Why? Simply because I don't have room for anything more, and probably won't have room for a long, long time. That's ok though, since with some modifications both mill and lathe are capable of doing good work. Not very fast, but still capable. A machinist friend told me anyone can produce good work on a good machine, but a good machinist can produce good work even on a bad machine.
Since they're going to be with me for some time, the decision to upgrade them and make them easier to use was an easy one to reach.
