I am not good at finding threads but there is a thread on this board about building a plasma table. I would also suggust joing the Mach !! email list as there has beeen several Plasma tables discussed over the years. The motors for a plasma table can usually be small compared to a router as all they have to do is carry the torch. You need THC and again there is some support for that on the Mach email list. There are several pictures and build threads for Plasma tables here on the ZONE. DO soem searches and see what pops up.
