^ good site, that has amana plastic cutting bits, in all the sizes you could need(depending on your router)
ill get some pics tomorrow, its basicaly, a 2ft x 4ft sheet of plywood on a 2x4 based stand, with a hole off to the right side for my router bit to stick up through. Id like to buy some masonite to sheet over top and wax it so it will give it that airhockey table effect.
