This is a simple project that only takes 15 minutes; it took me longer to take and post the pictures. If you have a wooden picnic table and an abandoned lawnmower laying behind the garage, you have the ingredients of a rolling table. Adding a set of lawnmower wheels to the legs of the table makes it easy to move it around the yard, while not dragging the legs and tearing up the lawn.

Tools: A wrench and drill.
Parts: Two 3-inch lag screws with washers and two small lawnmower wheels.

First, prop up the legs on something and place the wheel so it hangs 1/2 inch below the leg. You'll also want to have the wheel sticking out 1/2 inch on the outside of the leg (see pictures in the gallery). Mark your hole location and pre-drill the hole for the lag screw; do this on both table legs. Attach the wheels with the lag screws, but don't overtighten. That's it!

Now you can pick up one side of the table and roll it around like a wheelbarrow. This only works on lawns, not hard surfaces. The wheels can't support people weight on patios and other hard surfaces, but on the lawn they'll sink in a little so the weight rests on the legs. You could double the wheels for extra strength; then you would need long bolts instead of lag screws.
