I had a little welding project this morning but the welder was out of gas. The tank holds 11 gallons and I didn't want to make multiple trips with a gallon can. I went to the hardware store and picked up a five gallon can.
If you think gas is expensive, go buy a gas can. The California legal, environmentally safe can cost twice as much as the gas to fill it.
It would have cost less to have someone weld my scraper for me.
