Because I had on hand all the materials, it took me just under two hours to construct the license-plate bowl (not counting cleaning and clear-coat, which I have not done). So even at $10 an hour I'm losing by making it. The tools needed include a power drill, tin snips, good pliers, vice grips (locking pliers), rivet gun, wrenches, a vice, hacksaw, tape measure, rubber mallet, and either a good metal file or a grinding wheel. It so happens I have all that stuff, plus a capacious shop to work in, having married relatively well. You probably have this stuff too, now—or can borrow it from a nearby tool library. But not everyone has access to these tools. If I had to make this bowl 20 years ago, in my jigsaw-and-hammer-only days, it would have taken half a day.
