Like Some of the other guys here, My Tool Cart is homemade!
I started with a large steel box that I had laying around for years, it was build to mount on the front of a homemade trailer, to hold chains, tow ropes etc.
I really didnt know what to do with it until this.
I welded some legs, with 2X3" tubing that I had laying around.
Added cross supports, locking swivel casters, a steel plate and angle iron on the bottom.
I cut up a Craftsman 3 drawer box and welded it in the front of the Toolcart.
Added a handle, an outdoor waterproof outlet-Box with an extention cord that is wrapped up on the back of the toolcart.
Added a rubber matt on top, A handle and chains for the lid.
Added a sidebox under the box that I bought off of Mickey O...looks like it belongs there, doesnt it?...trust me...it was just dumb luck!
Made my own fold-up side tray and under the lid is trays, compartments etc...for all my spare tools...I use this for Driveway repairs...it is Heavy as Hell, but rolls nicely...and it will be around alot longer than me!
its still not done, I am Painting it Chevy Orange, adding a few spare 1965 Impala SS Flags to it...just seeing what it ends up looking like...sorta a "work in Progress"
