My best find after a lot of looking was an 11" round heavy stainless steam table insert from Smart & Final. It has made such a difference getting smelting out of my casting pot. I wasn't doing wheel weights but some of my scrap was oxidized. I was dreaming of a welded bottom pour but the 4 1/2 oz stainless steel restaurant portion ladle I've been using doesn't pick up the crud on the bottom and holds about 3# of lead.
