Well I'm going to build a cnc plasma cutter. I have everything I need except the steel and was wondering what size of square tube I should use. It will be 5 x 5 table and I want to make it out of 2x2x.125 wall square tube. My question is do you guys think that the .125 wall will be heavy enough or should I go with something thicker.
Any help would be great.

Thanks Mike
