Interesting DC solution. I take it the plate isn't ferrous metal so the magnets have to be secured to the iron table only. That would put it 4-6 inches back from the bit. Mag switches on the base of the fence will most likely work, Kreg has a mag fence for band saws that I've heard works OK. The DC setup could be clipped onto the base of the fence by adding a couple of metal plates for the DC unit to clip on to. That would allow you to put the DC over the plate, closer to the bit. Just my 2 cents.
