I hope you don't mind but a friend and I came up with two questions that neither one of us could answer at
least not correctly. Both of us have only worked with aluminum and cold rolled so anything else brings up
more questions than answers. The thing we were curious about is if there is a way to fuse copper together
so that it can be hammered and not crack.
The Tinman Respondeth:
Copper may be welded with deoxidized copper filler, and then hammered beautifully.
