Used the red neck shears to chop them up and the industrial sized oxy/acety to heat them about 2 pounds per cook before each water dunk. A hodge podge mix of handy sizes. Will tumble all but the long strips to remove burrs and oxidation in a rotary tumbler w/polished pea granite. The long strips are real nice. About 1/32" thick and 3/16" wide. Nice rounded edges. Used in transformer and motor windings. If i was serious about making copper jewelry i would pursue all sizes of this shape.

Won't the tumbling harden the copper and make you have to anneal again?

Won't the tumbling harden the copper and make you have to anneal again? Maybe the surface a little. I think physically crushing it with a hammer is the main reason for hardening Lee. I know they peen crankshafts is H/P cars. Hardens the surface. But i think they really fire the shot in to the point it dents the surface. Copper is such a mushy metal it may pad itself. About have to anneal two more times if say flattening say a 3/16" wire to less than 1/16" sheet. The copper will let you know when it has had enough. A vib probably has the ability to harden the surface like rifle brass. I never thought about it. I do not own a vib so can not say from experience.

How serious can a fella get James? LOL connrock I am stock piling a lot of materials Tom. For when things slow down. Still have to work and earn a living. When i get less active i will hit the jewelry hard. In a few years. Learned one thing about metals. They are always getting more expensive. I bought 4 tractor trailers of scrap steel almost 20 years ago and set it off hidden in the woods. It is about used up. And most of it was bought for a few cents a pound. I collect the odd shapes of copper, brass, german silver and stainless when the prices are right. Stock piling it too. Making pieces occasionally to see what types and sizes can be useful. And of those four coppers i just annealed variation existed. Some alloy differences were obviously present. But negligible. Brass can have much variation. And soft stainless is not common. Stainless that is rusting is usually softer. So rust is good... Have learned to observe color, stiffness and corrosion to decipher what is workable. And that flat transformer/motor winding copper strip is very soft to allow it to be wound tightly around armatures. It is cat's meow of copper but hard to find in the scrap yards.
