I have tons (literally) of the 2" X 4" X 8" pure lead blocks that I would like to melt and alloy in batches then cast smaller ingots for 20 pound melters for casting. ANyone have DIY designs or concepts?
Thank you,
Charles

Personally, I render down my COWW, and other lead in
a Large stainless steel mixing bowl to which I added a bail, like a bucket. It will hold 60 pounds of lead, or lead alloy. 

I use a propane turkey fryer for the heat which would be able to melt larger pot of lead than my mixing bowl.

Other's have used a cast iron dutch oven for larger batches of lead.
I, like Bob, use muffin tins to cast my "ingots"
They cost almost nothing at rummage sales.

Some guys report having sawn a propane tank in two.

I built one that holds 900 lbs.
Will get in touch later.

I have found that the log splitter works ok for breaking up bricks.

The turkey fryer looks good if I use a large ladle. Wondering if there are any direct pouring or bottom drain DYIs.

Thank you,
Charles

I use a Dutch oven and a crawfish boiler/Turkey fryer heater.

I melt ~60-65 lb. at a time, adding the necessary amount of tin when the lead is melted.  I generally do 4 batches at one sitting, and use Lyman/Saeco ingot moulds.  I mix the batches and store them in 50 cal ammo cans-each can will store ~120 lb of alloy carefully packed.

I went to the Goodwill and bought a cheap cast iron pot, and use a propane burner to melt down large batches of scrap lead into smaller ingots.
I have a mold made from angle iron to make triangle ingots, and also a muffin pan that makes 2 lb. ingots.

I cut a stainless pony keg (7-1/2gal) in about half.
Fits very well over the turkey fryer.  I then use the turkey fryer AND a weed burner to go from cold scrap to molten.   Did very well for both 300 and 400 lb batches.
