Thread: Casting a brass nut.

I found this interesting; the forge is certainly a lot easier to make than my method of lining an old car wheel with clay!

Bare legs!

Thanks Skew for linking to that, safety concerns aside, its a good demonstration that you don't need much equipment to do casting.

I know nothing about casting. Well, the only casting I have ever done was to make lead sinkers out of wheel balancing weights found on the road when I was a kid!

So, from purely an interest point of view I found it worthwhile to watch. I just want to go and cast things now.... I have no need to cast anything at the moment but that has never stopped me in the past!

BWT, I'm assuming you would not be able to attain sufficient temps to use it for cast iron?

Hi Simon,
Ray does cast iron, his set up it a little more complex.

That set up might get you there, a lid would help.


Not sure why he is reheating and quenching?

I know why you would do that with iron based metals but I don't know of the benifits for brass. I have never heard of hardening and tempering brass before... Maybe it's another reason, maybe you can with brass. I'm no metallurgist. Can't even spell it!

Often quenching copper alloys from the correct temp will anneal the piece; basically the opposite effect to steel alloys.
Maybe he did it so the polishing would be easier??
I wonder what the nuts were for? Was the thread meant to work or are they ornamental?
