    That place reminds me of where I worked when I was about 20 - 25. Made brass plumbing products as well. That was only about 42 years ago here in Australia. I'm 67 now. Dirt floor in foundry with machine shop right next to it and a plating shop across from the machine shop. Even the machine shop had a dirt floor if IIRC. Lathes were on timber sleepers I think. Line shafts to most of them. We did wear boots though. Not much in the way of dust or fume extraction just whatever breeze went through the building.

    Actually that is quite correct. I have worked in some of the old foundries that were over 100 yrs old, in the Buffalo area. You would have been shocked at the conditions, and yet many of the original machines are still there, and making money for the current owners. A large chunk of the Industrial Revolution was built here, and little signs of evidence remain everywhere.... such as the number of cancer cases, family stories from the Depression, etc.

    And of course, the gutted-out factories and ghettoes everywhere.

    As an example, the 600 HP Snow engines were made here, I've worked in the foundry where this beast was poured and machined: https://www.youtube.com/watch?v=dhpwbBwSIAs

    they have a VTL with an 18-foot dia chuck (!) among other tooling of equal size. Well over a hundred yrs old and still in use, dirt floor and all....

    There's a good reason for that. Aluminium isn't bad but brass or iron can heat shock concrete and cause it to spall with an almost explosive power. And that tends to spatter the very hot or even still molten metal all over the place along with the pieces of concrete much like a land mine. So a few inches of old casting sand that is past it's "best by date" is a nice safety feature.

    @ 1:01 inserting shell sand cores, I would like to what they use to make them.

    That's probably the best of all -- likely it was the casting sand itself. Very large foundries (Bethlehem Steel) used to do it that way when pouring pig iron.

    Well actually, dirt or gravel is safer because it doesn't explode when molten metal splashes on it. Concrete will explode from the steam when molten metal lands on it, and the explosion will spray bits of rock and molten metal, right into your body. Whereas, dirt or gravel just dissipates it, the molten metal solidifies and the surrounding area gives off a fog of steam.
    I have actually experienced both things a time or two.

    I was blissfully unaware....but in my defense I don't go round with molten metal! I thought The Artful Bodger meant they'd classified the floor being dirty as being the hazard but I take it from what you've just said that the floor should be either dirt or gravel presumably so the molten metal doesn't run off if spilled. Not planning to slop slag about....but you know, for interest's sake

    He gave them a gentle education regarding safety in a foundry.

    (No one needs molten metal poured into a boot he cant kick off quickly, never spill molten metal on a concrete floor. etc etc.)
    I am amazed that people need to be taught this. While I have never worked in a functioning foundry, I have spent a lifetime around heavy welding, etc in abandoned foundries. Dirt or gravel especially is your friend.

    Plating. 3-4 volts DC max at maybe 3-5 amps. No biggie.

    I'm pretty sure both Sarge and George mean abrasive emery cloth. I've seen this suggestion in the past. The idea is to put the abrasive side inward onto the more slippery metal.

    Another option is to turn a close fitting outside bushing where the brass just fits. Then cut a split so it acts like a collet. More surface area means more grip. And no risk of deforming the pipe into a tri-oval with excess pressure.
    Yep. Both George and bcrider are right. Its the abrasive stuff that is on a roll of cloth, usually 1" or 2' wide. Where I worked, it was called stripcloth, commonly made by Norton or 3M among others. Just got on MSC's website and checked, they call it shop rolls and cloth backed shop rolls.
