Rough Sketchup drawing

Here is my peliminary idea for what I want in a CNC Router. Not even close to being done, but it is a start.

This one is using 3 inch cold rolled plates as part of the linear motion. I’m thinking about using some angle that has been trued up on a mill. Don’t know if that is a good idea or not though.

I might also have to build an ‘ugly’ CNC before I can build what I really want though. Meaning that I may build an MDF with all thread, just so I can make some of my own parts for a machine worth having.
