 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 :

Spoiler: show

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.

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'm liking the wedge/sledge approach for minimizing the errant poisonous particles. And maintaining a reasonable level of precision.

How can I help you, and/or make you smile, today?

The problem with being on social media, is that you know too many people that you don't know.

Joy is not a feeling. It is a strength. Some people are stupid, that's all there is to it. (And sometimes that stupid person is me/you.) Sometimes you just have to let stupid people be stupid. Don't let stupid steal your joy.

Holding onto unforgiveness and resentment is like drinking poison and expecting that other person to die. Anger will eat you up.

Oh sure, do it the easy way!! icon_eek work smart not hard. I like it Ren.

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.

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.

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.

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.
