Default Copper shaft

I found a copper shaft in one of my local used parts supply depots. I picked it up and racked it with some other shafts.

I looked in the book and it is expensive. They didn't even offer the size I picked up.

My question is, what is it good for? Will it work in place of brass for a bushing? I cut a piece off the end and made a non spark hammer but it must have more suitable uses. It is 2" X3' no marks or holes or anything.

I can't imagine it's good for much, do you need my shipping address?

Jerry, the arms on the spot welders where I spent most of my working life, were about that size.

I made some specialty tips for a spot welder out of some 1/2" dia. stock. That's about all I got.

Hammers are good. Bearings? I don't think they'll last very long. Is it dead soft?

I am not sure what dead soft is. It is dark colored but when cut comes out bright. I sawed it with a bandsaw and it works like brass. It drilled and tapped easily. I can't think of any use for a 2" shaft. I would expect it to have something to do with electricity but I found it in the junk yard behind the John Deere dealers shop. I have also found bars there before. They were about 1/2"x4"x16". Those has two holes, one at each end but no other marks.

Now you can finish your welding positioner and make some contact bushings.


I cant remember, I think a steady rest I used had copper wear pads.
Or it had red brass, high copper content.

I have a parts problem with the weld positioner. A local farmer gave me a gearbox from a sprinkler system. During a repair with a flat and bent wheel it had been deemed bad and was replaced. These boxes cost about $1500 each. Usually there is a bearing problem and water in the box. I needed to replace the bearing and check the teeth on the box. When I opened it I found the grease was good and the teeth were good and all bearings were good. Some over achiever had replaced a good box. I installed new gaskets and seals and told the farmer. He was very happy to have a good spare but I am out a gearbox. Another will come along.

How do you tell the difference between red brass and copper. What I have is not soft. It really works like brass.

One thing that come to mind is a backing for welding parts together without any slag or burnthrough,

OM, I was going to use a sprinkler gear box to make a ring roller. I located an old sprinkler laying in the weeds and talked to the owner. He priced the gearboxes to me at $100, let me know if you need one.

I don't really know, It can be a tough call with what I have seen.

Copper can also mimic brass, with age copper wire gets brittle and hard and seems to cut more like brass.
Or they can work it hard and add alloys making it hard.

Copper house wire is probably close to dead soft.

What you can do. anneal a piece of what you have and see if it gets as soft as copper wire.
Cut off a piece about .050 thick, heat it to a red hot cherry color and immediately quench it in water.
then try bending it, if it bends like copper wire it probably is copper.
