I put a BIG stock pot on the side burner of my gas grill and fire it up. I've got a stainless stock pot set that I use for canning, big batches of chili or beef stew, etc., It holds about 5 gallons. Since it's holding only water, it serves double duty as a rinse water pot for building engines. I just use a small saucepan as a dipper and flood the cylinders repeatedly with the scalding water. It evaporates almost instantly and I oil 'em down right away.
