Boring heads for the mill

[EdK]

Anybody every made their own boring head? It seems like it would be a nice project for someone that has some experience under their belt and is looking for a slightly more challenging project than the typical beginners projects. Or am I all wrong about how hard it is to make one? It wouldn't be the first, or last, time I was wrong about something like this.

By the way Dan, I'm not suggesting you make one instead of buy one.
