anyone know

a buddy of mine was working on an old bridge , tearing it down and found what looks like lead pipe that has a bunch of copper wire running through it. It was burried under a stream running under the bridge. Does anyone know anything about this stuff, pure lead or something else. Thanks

Yes, it's old power/control cable and that is how they made it. It should be pure enough for M/L's. I have not seen any of this stuff for quite a number of years. .....

It is called, "cable sheathing", and yes, it is pure lead. Modern cable sheathing is mild steel or plastic.

You can harden it up quick for general casting purposes by adding some shot to it.

Use a hand torch to melt a cut in it.

I used a hand axe to split it open down it's length and then peel it open in about 18" sections. Then removed the copper. depending on the conductors, you can salvage the copper as a bonus. As I said before, this was a long time ago but I do remember that the wall was not that thick. .....

There are two choices when it comes to separating the lead cable sheathing from the internal copper wires. You can cut the lead off (I used a hatchet), or melt the lead off. If you melt the lead, the insulation on the copper wires will burn and smoke, but the lead will separate and the copper can be lifted out of the smelting container.
