Show off your copper stuff!
I'll start it off
sure, it would be cool to see some pics of parts.
Almost everything I've made using copper has been internal heatsinks like the following:sure, it would be cool to see some pics of parts.
I think it would be nice to get some bezels or other parts made from copper to use on lego type lights like surefire or solarforce lights.
In the pictures it looks like copper with some zinc added = brass. Nice looking knife!
Little knife is supposed to be copper handle with shell inlay and damascus blade. Not so sure on the copper part though. Tested it with multimeter and it isnt sealed and with my neodymium magnets they didnt stick to it so maybe a alloy or something. It has a slight smell like copper but not sure yet. tarnish will tell more hopefully.
I got the copper sphere off from Ebay. It cost me $34 shipped to my house and its 99.9% native Michigan copper.
Its approx 50mm in diameter and about 1lb (will weigh with scale when I get one). It is coated so it wont tarnish, which im considering removing, but I guess for that could be less cleaning. It also came with the little stand, which is made of wood I think.
There was a few other diameters, but this was the biggest I could find. There were a few at 30mm and 40mm also.
I saw and had to have it, and wife thinks i'm nuts, but its just so much copper.......
I got it just for a large specimen of copper, and I liked it.OK, it's decorative. I was wondering what it was for. $34 isn't expensive for that much cool. A Google search for copper sphere produced 9,970,000 hits. Who knew!?

Let me rephrase that. Copper requires razor sharp tooling and plenty of lubricating oil. If your tooling is a bit dull then the copper does not cut nicely. I have to rotate my cutting inserts constantly when working on copper, sometimes two or three times for one part while I can use one insert for many times the aluminum parts.Copper dulls carbide? How? It's such a soft metal.
