I have a copper bar that I am deciding whether to keep it (1x2x15"). Icannot think of any hobby style need that would involve a copper barlike that. I have other bars that are more practicable, like0.25x2x15, etc, these are quite useful for all sorts of things, suchas in my welder conversion, etc. But I cannot see any need for makingparts from big thick copper bars. Aluminum would always be cheaper,have good electrical and thermal properties, and easier to machine.Is that, in fact, true?i

I would hang on to it. I have the occasional need to make bus-bar "bugs", and other high-current connectors and contacts.Last year, I had to make all new rheostat studs for my very (very) old EZ-GO golf cart. They'd discontinued the part.Nothin' for it but copper rod, lathe time, and some frustration getting my rake angles right.(single-point threading of copper is a pain in the ass!)LLoyd

Well, the glue is no good anymore, you have to use the clips I will send With the machine that does it, old people can't hear the click, click anymore, right? If you can just put some 60's rock & roll on like the rolling stones....

Gee, that is only tooling needed for a job..& it should be a write off on taxes..

I built a spot welder and used something similar for the electrodes.
