Here's my first attempt at building a CNC mill for aluminum/steel machining. It's roughly 90% done at this point and just needs a few plates for the X axis, and some beefy steppers.

(This is on my home connection so we'll see how it holds up!)

I have a Sherline mill that I converted to CNC a few years ago and I've stressed the thing to its limits making the new mill.

I'll go ahead an leave the images on my web server so you guys can see them all in one place. More details soon...

Enjoy!
