I made this compressor cart about 1 1/2 years ago. It was my first “cart” and I kind of stole ideas from several sources ( including LJ) and combined them to make this. It is made of 1/2 plywood with a 1” oak dowel for a handle. The top drawer has room for air tool accessories and nail gun nails, etc. The side shelves fit the cases to my air tools. The wheels are 6” lawnmower wheels in back attached with a 5/8 threaded rod and nylon bearings where the rod goes through the frame. That area is also gusseted by some scrap 2×4. During the assembly I had gotten so ahead of myself that I had put one side panel backwards and nailed and glued it. My 17 year old daughter, while asking me to borrow the car, said “is that supposed to be backwards”. I said no and handed her the keys. So I finally got it put together and wouldn’t you know it 6 months later we moved and I had to get rid of it so all the antique furniture my wife bought (for me to refurbish as a project) would fit in the moving truck. Oh well, at least I have these photos to go by to build another one.
