| My dad told me it is pure lead - it's a calibrated weight - 1640 lbs.

| A friend used to buy 2000 lb. pigs from the foundry. He used an acetylene torch to work it down. I doubt if that was very cost effective.
I would be tempted to put it in a fire pit, with trenching leading away, and melting it that way to get it to a managable size. That's the way the Indians and early explorers in the Mississippi valley lead region used to do it. You would still need to clean it well before casting, but it would be smaller to deal with! |

| Lay down a tarp to catch the chips and go at it with a chain saw, nice even slices, and the oil on the chips ain't too bad a flux. |

| I use SAE 30 nondetergent motor oil from an oil can for fluxing. Works fine, doesn't stink, and it sure is handy! It's pretty much the same as paraffin wax, really. |

| I've used a log splitting maul, sledge and splitting wedges to break off chunks that fit into my pot. I did try a propane torch once...don't waste your time and money...I don't recommend any type of carbide bits either..just gums them up.

| I had a pure pb chunk given to me once that was the size of a 5 gal bucket.After all of the above ideas,I used a air chisel. I found that the flat wide heads work the best [1.5"] Have a extra bit or two around to get the first un stuck.Trust me.It took a while to carv up that entire hunk. Now on lead with a smaller cross section this works like a dream I have also heard that a plasma cutting torch works well but a Oxy/acetylene cutting torch is a waste of time and money. |

| Hello: I'd be a more than a little concerned about toxic fumes, while using any kind of torch. Grizz |

| I'd be inclined to combine the firepit notion with a split 55 gallon drum. Length of pipe in the smaller hole in the head of the drum could channel the lead as it melted into ingot moulds.
You have a problem all right, but it's a problem I would not mind having. |

| Felix, I was suggesting an intentional leak. The safest way to get that mighty chunk of lead into ingots is to channel the lead off as it melts. I wouldn't want any part of 3/4 of a ton of molten lead.
Let it drain into moulds as it melts and you minimise the risk. |

| Reminds me of a story my boss told me of when as a teen-ager he worked in a small brass foundry. They got a BIG job, bigger than any of their flasks would take, so dug a pit in the dirt floor, filled it with moulding sand and rammed up around the pattern (it was a single-sided job, open on the upper face). They heated up three or four of their biggest crucibles (not being sure just how much metal they needed) and started pouring. It took the first couple crucibles and needed more, so they kept on pouring, until they heard a big "bang" and clatter outside in the alleyway. Looked out and saw manhole covers leaping into the air down the alley, followed by clouds of steam; you guessed it! They had broken through into the shop sewer line. floodgate |

| Rick....That's what I'd use. I use to do old batteries that way before I figured out it was too much work.
I did do one ingot like that that had been poured ina hand wash basin. Only way I could figure to get it rendered down./beagle |
