Hello and thanks for watching.I don't know about the nutrient effects, but the whole idea of the oligodynamic effect is very interesting. I can't say for sure about MG burning, but that I the reason I don't want to burn MG in my hobby foundry.

I haven't tried that myself, but I have seen someone try 25% CU +75% AL and it was very brittle. I can't say for sure but I would think just 11% CU would also be brittle.

I don't know what jewelery is. Good catch. I'll blame dyslexia on that one. Good call about the difference between AL, MG, and ZN. You don't want to be melting (or at least I don't) magnesium because of the chance it could start a MG fire. That would be scary. So far, everything I thought was AL has been AL. I found many PC heatsinks and I believe they are all AL. And a builder friend of mine gave me all his AL railing cutoffs. That was a nice score. I have a bucket of ZN from faucets. Under the chrome or nickel finish it still looks silver, but is heavier that AL. Some others are brass coated with chrome. Melting ZN also gives off a toxic vapor as it boils away. Same with brass, due to the ZN in it.

Hello,1. I was going from what I was told, but I have not had any formal training on the matter. So, I would go from what your teachers said. The only thing that made sense to me was to get the lower temp metal melted first, then when the higher temp metal is dropped in, the whole surface area would be covered and heat it that much faster. But then again, I don't know what I'm talking about :-) That could be way off.2. I would love to cast bronze bells. One day I'm trying that. I believe water or oil quenching or not quenching, but air cooling all help with bringing out different qualities in your metal. I found some info here: http://www.nationalbronze.com/News/important-featu...3. I figured it would, but was surprised by how quickly it did. That is why I usually put my molds in a tray...

Thanks for watching

That would be really cool. One day I’d love too work with a lathe. Please do send pictures when you get to it. Thanks

Very Interesting! Can you describe the taste? Great Instructable!

I haven't tried machining it, as I don't have the correct tools for the job. I have stamped it and it is very hard. The stamped letters barely show up. Quenching it in water is always fun to see. If you make some, I would be interested in seeing it. I might try casting the pulley and cleaning it up on a bench grinder. Lost Foam casting would be good for that. I may put out an instructable on that method soon.

Awesome! I have to say, it's surprisingly good. :-)

That is beautiful! Great work and great Instructable!

A knife would be cool, but I don't think it would keep an edge. I think I got the disks for $12 with a coupon. Here's the link https://www.harborfreight.com/5-piece-4-inch-polishing-wheel-set-65287.html

Hello, it was casted into homemade greensand. A mixture of 90% filtered play sand (finer the better) and 10% ground natural kittie litter. With a bit of water to help it bind. But the polish was with an angle grinder. I got a polishing set of “grinding disks” from Harbor Freight. It goes up to 600 grit. Hope that helps.

That sounds very interesting. I would love to be able to do that but I’m not sure I can get my furnace hot enough to melt nickel. That melts around 2800deg F. You are right though, it is strangely satisfying melting and casting metal. Thank you.

That is really cool! And nerds are awesome! Thanks for the comment.

This looks great! Couple of questions. Did you glue the head onto the body? A couple of strong magnets may work for that. And how do you keep it from rolling over? Terrific job and thank you for sharing.

That is great. Thanks!

I don't think the paperclips or brads resist much electricity. They are more like wires.

That is fantastic!!! Tell him I said great job!

Mostly on-line but sometimes Radioshack.
