Hi Shedman,
I have built a CNC router (X:600 Y:1000 Z:150) and have a 50W CO2 Laser. I also build model planes! I can show you what I have built and offer some advice and your more than welcome to visit for a look.
Do you want to buy or build a CNC router? Do you any CAD experience? Do you want to machine 2.5 axis or 3 axis parts?
Regards Simon (Cube3 - Product Design)
