Crikey, I did start a project a few back when I was into modding, but I only used a hand held router. Acrylic routes nicely providing you use a low spindle speed and high feedrate. I used regular up-cutting spiral cutter but I believe there are specialist PCD ones available if you have a few quid to spend.
