Score!!

Mods: if wrong forum please move to the correct location.

I’m a truck driver. I’m sitting in the truck and there is a pile of trash by the dock. I’m looking and it seemed to have two lead weights laying there. About ten pounds or so. I helped take out the trash. Attachment 265220

Your a good man!

What do you think they are? Purpose I mean.

Some sort of counter weight? Used in testing of something. Must be for testing a blast door, one that opens in an overpressure situation?Attachment 265222
It’s says “press 0.509 PSIG”. That isn’t much pressure.

No not alone it isn’t much pressure but I’ve heard of pressure tested fuel and water tanks on ships popping when just a half a psi too much pressure is applied. I haven’t personally observed a tank hydro in years but if I recall corrected they get tested to 1.5-2 psi. Too much and they pop because those pounds per square inch are applied over a huge surface.

Never seen such a thing.

Very interesting find. Serial numbered too!

Matched set.

One of two
Two of two.

Could be weights to generate that pressure in a test cell of some type. That weight applied to a piston of set diameter generates the specified pressure used to calibrate an old school sensor.
At any rate, I have some 18 inch x 24 inch cone inch thick counterweight plates. I believe they may have a bit of tin, as they will cast a decently filled out bullet. I just call it plain lead. Good score, and you kept that terribleness out of the landfill:)

Good find ! Free lead is the best lead.

Nice score! Those are very interesting.

Great find
Well done
You have saved us from Rampant Lead :)

Good job of keeping the environment safe!

Very nice score. and at the best price!

Sweet!

Looks like the weights to a vacuum/vent device used on an above-ground storage tank. Either way, good score!!!!!!!!!!!!!!!!!
