Building My Engraver

I've been spending a lot of time and money building an engraver. Basically it's a computer controlled machine that will engrave images into wood, plastic, and aluminum. I plan to use it to engrave photos into wood and some of the other many uses I have in my head for it.

It's still not done, but it's getting there. Here is an image of it:
Here is a link to more details about the build so far and a lot more pictures.
