I bought a MicroLux 7x14 mini-lathe (micro-mark) several years ago for a metal machining project. After buying most of the tooling from Little Machine Shop, I started making pens on it about 3 years ago. I find that the ability to accurately determine the amount of tool movement, bore holes, and cut threads offsets some of the freehand abilities of the wood lathe. When I get some more room, I'll probably add a wood lathe.
