Going to be embarking on a welding cart build in the not too distant future. Grabbed a free 2 drawer filing cabinet off of the book of faces marketplace to use as the "base cabinet" for the machine because I'm super cheap. Thinking I'll weld up a frame out of angle for it to sit on, put the tank on the back with some 1.25" filler rod holders. May throw a boom on there to hold the torch hoses up off the floor. Top drawer will be for all of my PPE, references, notebooks/clipboard, marking tools. Bottom drawer will have my foot pedal, torch, ground clamp, torch consumables, grinders and wrench, discs (separate sealed container for the ones dedicated for AL), Tungsten grinder and discs.
Will also be building/repurposing my DeWalt jobsite saw stand I think to be the base to a mobile welding table. Was going to get rid of it, but now I'm thinking I'll repurpose it since it's "free" steel. I want to buy the titanium "fab" table from HF since it's cheap and I can pop it on top of my track saw cart/assembly table.
