Cutting up a decent size chunk of lead

I've been avoiding this particular chunk for a few years. It's 18.5" x 26" x 3.5", Somewhere between 650 and 700 pounds.
I don't like the idea of using a fast saw like a chainsaw : https://youtu.be/H5oz9IJ_5O0
Want to minimize particulate. Of course, the chainsaw throws big chunks, but there must be a bunch of small particles too. This is too big to fit in the big cast iron babbit kettles... Thinking of using a sawzall type with a wood cutting blade. Anyone chopped up a big piece of lead like this and have some experience to share? Thanks in advance. |

What about a fine tipped torch and just melt threw it? Or a bend break type press....

Wood splitting wedge and maul or sledge hammer. Create a series of deep "V" grooves on each side that meet in the middle. If they don't go all the way through, should be close enough to bend back and forth a couple times until breaks.
Or... Good respirator and plasma cutter. _________________ I always thought growing old would take a lot longer..... So, when does that "Old enough to know better" shit kick in??? I've learned that pleasing everyone is impossible, but pissing everyone off is a piece of cake. |

No offense Mike, but this sounds like more of a job for the Balrog.

I like the wedge idea, but use your hydraulic press to do all the wedge driving to save on your delicate physiology.

I would chop that fucker into chunks with a nice sharp manly piece of steel on the end of a hickory stick.

I'm liking the wedge/sledge approach for minimizing the errant poisonous particles. And maintaining a reasonable level of precision. _________________ -Jeff How can I help you, and/or make you smile, today? You are entitled to your opinion.

I figured once pointed in that direction, Mike would take it from there. Just a hydraulic log splitter would work. Or tack weld a fashioned metal wedge onto the underside of a forklift fork, and press down on suitable backing "anvil". Actually bandsaws work pretty well too. _________________ I always thought growing old would take a lot longer..... So, when does that "Old enough to know better" shit kick in???

Now I personally know jack shit about the topic at hand. But some quick research definitely favors a splitting technique over sawing.
Some top rated suggestions were for using a press with a brickset head or using a wood splitter with a similar separating head. I’d personally be wary to use a saw and put a load of lead particulate in the air and ground. _________________ Licensed/Bonded/Insured Hardwood Floor Installer/Finisher http://www.hardwoodfloorsnw.com/ |

I had a chunk that size. It was a PITA. A sawsall will make a mess and waste lead. I used and old axe and a maul. If I had to do it again I would just use a hand held propane torch.

That is what I wound up doing...... Propane is cheap, compared to elbow grease. I was NOT going to let that chunk of lead beat me. I positioned it so that it dribbled right into the pot or mold. While I won't turn up my nose on (free) lead.... I sure don't go looking for large chunks anymore. _________________ US2A.org is done. Closed.

All very good suggestions. Thank you gentlemen.
I wound up doing what MadPick suggested. I lowered the slab of lead into the Balrog's cage with the crane, and she's about halfway through biting it into 1 pound chunks. |
