Man I would sure like to find a way to use my PC 7310 for sign routing. A plunge base of some sort, clear plastic, would solve ALL my problems. At the moment I am driving myself crazy using a "sign making kit" I bought from Woodcrappers Supply. The weight of my router distorts it and I tear up the plastic templates. And the frame. It is a NIGHTMARE....and it cost me $40! Drat!
