Step 1: A Base...
I think it was a Luxor Endura...it's a hard plastic cart and the shelves are about 4" thick. The shelves connect together with sets of plastic poles (it looks like PVC pipe).
You may have wood shelves/boards, or you may have some other type of plastic shelves laying about.
Step 2: The Hardware
- (4) 7" lawn-mower wheels, which I found at Home Depot for about $5/each.
- (4) 3/8" bolts of about 4" in length, with about 75% of it being the shank.
- Matching washers, nuts, and lock nuts.
- 8' of rope (of your choice).
- Drill with a 3/8" bit, and a smaller bit to start.
- Possibly a larger bit for the rope...
- A couple of wrenches to match.
- A level, tape measurer, ruler, etc.
Step 3: Wheel Assembly
Based on the structure of the shelf I had to work with, I went through two sections of plastic for each bolt.
To assemble the wheels, run the bolt through the front of the wheel (preferrably with the plastic wheel insert from the manufacturer), add a washer, and then drop the wheels into place.
Then, tighten the machine nuts using your fingers and follow it up with the lock-nuts (using your wrenches). This is a cheap-n-dirty way to keep the bolts tight, while allowing for the wheels to spin.
Step 4: The Handle
Give it a good tug or two.
