RE: casting
Well what I did was for a heat source, I bought a turkey cooker when it was on sale at Menards (like Home Depot in the north here) for $19.95. It came with a stand, a regulator, and a Bunsen burner type gas heat source that can be controlled. I then wired an old gas stove grate to the stand. The pot was just an extra and something to use to cook turkey in for the little woman and friends.
Then I boughta Lyman ladle, a simple Lyman melting pot, a bees wax candle, made a scraper out of some roof flashing, and some LEE Molds, and built a drop box that I lined with leather. I also bought a bottle of Rapine Mold lube. Lead i pick up here and there.
At least this way, if you don't like casting you have a turkey cooker that works excellent by the way... and a ladle and melting pot along with the molds. Not too much involved in it. And it is a fun thing to do. Just make sure there is no moisture around you or dripping off you when you cast, and the area is well vented. Lead fumes they say are dangerous.
