I'm sure you guys don't want to hear this but I want to try to learn a little about router work by making the large(w/dual 850oz servos)plasma table i'm building a dual function table. It will be a flooded water table for plasma work and I think the best way would be to drain that to do the router work as opposed to putting a top over it to do router work on. It seems like a vacuum chuck table is the premo way to go. But i'm open to suggestion for other methods and still not really sure how to make that happen.
