This is an older Husky mechanic cart that I built a laptop stand for, fabricated side storage for screw drivers, picks, nut drivers, and torx drivers. Changed to 4 wheel steering. It holds various chemicals and a spare battery and jump setup on the lower shelf.
This is used to roll up to and rapidly get to the computer on a car. Laptop is the oscilloscope, ODBii reader, engine computer, and youtube how do I fix that machine. This is the overflow for metric wrenches but I tossed in a basic 3/8 socket set for common things, the real mechanic set is in the other box.
Next up is going to be a sliding tray that runs over the wrenches that I can park parts on.
