Hello and thanks for all the great info and ideas here in the Zone. I have read through a lot of build logs (past and present) that have given me a wealth of information, without them I wouldn't be building my first cnc plasma table.
The bottom frame is 4" beam and the tank is 1/8" sheet, I formed up 2 pieces for the tank. Very heavy, good thing I had some help from the guys at the shop! The legs are 6" channel iron with pads and I am using a 6x4 angle for the linear rails to sit on.
