Re: Insert Cool Name Here 24x48 Build
I built my first machine from MDF. I was excited and didn't mind-the-details too much. Cut trapezoids instead of squares. I did re-build using 11-ply furniture-grade plywood. Sturdy and purdy (pretty).
I can machine 3/4" MDF, I also isolation rout PCBs (can easily do .050" pads for surface mount ICs), and for engraving aluminum and plastic. I have done some serious damage to one of my aluminum mounting clamps, so torque is not an issue.
Anyhow, for a light-duty hobby machine, I'm very pleased with it. (of course, I use the HobbyCNC PRO stepper motor driver!)
