Been playing around in sketchup ... I have in my possession 90+% of the parts now to really start building. after over a year watching the parts collection collect dust, it's time to put a plan into action.

Most of the structure has been layed out. I still need to sort out the bits that will be mounting to the gantry structure, but i think this is going to a workable design. It should be 4'x3' or so. The cutting area will be around 30" x 20" x 4-6"

Please point out any weaknesses in this approach, I'm sure there are many things I have overlooked.
