Nice cart I am getting ready to build one and I really like you design what gauge 1x1 tube did you use and what gauge sheet steel did you use for shelf is there cross bracing under the shelf? I have to get by with my encotig which weighs about 200 lbs. while I save my pennies for my 250ex or ext, your design looks like it will be perfect for putting my tig on second shelf and my hf251d-1 and cooler and plasma on top shelf any tips would be apprectated. Thanks Bill Nice SS in background.
