Advise on building a CNC table

[EddyCurrent]

I've just read it again, and not being up on plasma and water tables I assumed that plasma cutting was done on a bed of slats or inverted angle irons and that a water table referred to a T slot type affair for cutting aluminium with flood coolant/lube. Now I realise that the plasma and water table are one and the same thing. I need to lie down for an hour with some Slipknot full blast.
