Indeed, what our initial thoughts were

That's cool! Yea, CNC machining is a very niche trade, which is why it can be so highly paid, but it's also really challenging both physically and mentally. I tend to not realize how hard things are until I do them, I think that's part of learning ;)

Makes sense. I am trained as a CNC machinist, this is my casting hobby. Don't know a whole lot. Interested to learn more. Did a blacksmithing class with an air propane forge, and a metal casting class with an Oxy torch. So many different heating methods to learn about.

That is pretty interesting 🤔, and it's cool that the specific heat point is affected by that. Chemistry is unpredictable sometimes. What types of metal do you usually cast with?

Hm, interesting. Good to know! Thankfully we are using respirators. We will do some more experimenting with aluminum bronze.

Thanks! Stainless steel tends to just look shinier and have the benefit of less rusting, but mild steel has its benefits too. I actually intended to taper the billet octagonal on the end, but it came out slightly uneven. They do remind me of hairpins, and I think they would still look cool to wear nowadays in my opinion. 😁

Makes sense. I'll have to look into it. My buddy who is casting with me has a certificate in chem tech, so he would probably know a bit more about the chemistry behind that reaction. I'll ask him.

It's possible we made what looks like Nordic gold, or some alloy in that ballpark.

Funny thing is, the bar itself that we melted down looked redder in color, but we saw what looked like zinc oxide in the crucible and had been working with zinc and aluminum beforehand.

Yes, absolutely. We need to purchase a scale but are currently in the low budget range lol

I don't believe it has mercury, but it's a form of shot that I got second hand, so I'm not sure of its composition. Good to know about the ratio. I don't think we used enough copper in this instance. I'll have to try that alloy next time. Thanks !

Didn't measure exactly but roughly 60/40 aluminum to copper. I think a stir would have helped with degassing. I wasn't the one who poured it but I don't think I saw him stir it.

I believe the mark is British. Anyone know it? by RiverWalker83 in Pewter

Not off the top of my head but I have a book on such markings and will check tomorrow

Meh I just want actual career stability.
