Propane grill?

[Bill M]

When I got into casting, I realized I needed something to render lead. My friend had a genuine plumbers furnace, which was great, but I looked around and decided i had enough scrap iron to build one. The frame is a piece of Jr Channel with legs welded to it, the burner is from an RV water heater. The pot itself is 6.5" pipe with 1/2" plate welded to the bottom, and round stock welded to the sides so it can pivot/pour. I don't let it fill all the way up, and generally get about 70# per pour, leaving some to get the next batch melting.

Bayou Classic Jet burner with the solid steel bar frame for me. Effortlessly holds my half 20# propane tank pot with 240-250# of alloy.

Acorn, I use one of these:

Amazon carries them...probably Harbor Freight, too.

That burner is a good start but most of the heat just goes around the the pot. I have three pots, 60, 80 and 100#s and it took much longer than the old plumber's pot I have but alas it can no longer be filled anywhere due to no OPD device.

So I made a shield and lid to turn the 100,000 BTU burner into an oven and made a holder to heat the 10# cast iron pouring caldron to fill a commercial ignot maker that came out of a linotype shop. The lid on the oven has a threaded rod to pick it up and can be removed for storage.

This is what I use. At 200,000 BTU it will melt anything. Heavy-duty construction but I never go above about 50 pounds.

There's a reason RCBS make as a small casting pot! Use a propane stove and the small pot and you'll crank out some really good ingots fast. Smaller size pot helps to spot contaminated lead and spoils less than a large pot if not caught in time.
