How to tell if these are lead?

[NoBodyImportant]

We are replacing 8 robots and the ones going to the scrapyard have counter weights on them. I can get these for 25cent a lbs and they are 922lbs a piece. He said if I get all 8 of them I’d get a better deal. I can cut flakes off and melt them with a map torch very quickly. Any way to test them.

That acts like lead. Not many other metals you can cut with a knife and melt with a plumbers torch. Magnet test. Snipper test. Hardness tester are other methods but I expect the consensus to be lead.

I drilled one to seeing and they are solid

Group buy? I'm in for 1 if we can strap it to my elantra.

ETA: that's lead.

I want to watch.

I'd love to have one of those for a tractor rear ballast. Lead or not

I would have guessed they were hollow and filled with non expanding concrete. Pretty neat they are solid.

How big is the dang robot?

How big is the dang robot?

12ft tall. Not the biggest ones I ever worked on.

I don’t have a melting pot quite big enough…

Taste test?

Most Lowe’s and Home Depot’s sell lead test kits for about $10. Something along these lines:

How long do you have to decide, and can you shave off a small sample for testing?

I'd buy one or three in a heart beat, let me know.

Get a group buy going. I'm sure you can find eight buyers!

I’d take 200 lbs.

I had lead counter weights that looked like that from high end x-ray tables. Seems like the weighted around 350 a piece. The lead was very pure without much tin or other metals or impurities. The large mass was a big heat sink and I had to cut with a torch. I just added a little tin and shot most thru 44's.

Boil it in some vinegar and hydrogen peroxide and see if you make tasty, toxic lead sugar.
