Late on a Saturday afternoon (VERY LATE!!) we realized that if we took the spoilboard off the router, laminated and perforated a waste board, and turned on our air assist we would have a killer air hockey table!!
After a bit more consideration (and maybe another bear) we realized that we could mount a board to the head, move the gantry to the middle of the table, and set the head to travel back and forth on the Y axis as fast as possible. Viola, a moving barrier to add some more challenge!
Didn't try it just let, but who knows maybe if we burn out enough.....
