My friend, the farrier, has a chop saw and uses it for solid steel
and iron, and copper when necessary, since he makes corrective shoes
out of 1/4" thick steel, which is the thinnest he cuts with this,
some pieces are solid 4" diameter.
That’s what we used. We placed the tube on the table, the end of it
was on an adjustable stand to keep it level. It is copper, and the
pieces annealed easily. It was used in a plant in VA for a heating
system. They upgraded and disassembled the system and sold off the
The pipe is 3/32" thick. I was able to drill for the rivet designs
on one bangle, and hammer into wood for the anticlast bangle, and
hammer and stamp. On the anticlast I had to anneal between each round
but did not consider this was anything other than copper, but maybe
it is. If it is something different, I would love to know what it is,
that would be fun.
