I cut 2 different width flat wire stock to length
5mm and 4 mm width
stamped the infinity symbol
filed the ends flat and formed them so the ends meet flush
add flux and solder
start heating with a torch
quench in water and then clean in pickle solution
the black is oxidation that happens during torching
after the pickle bath
now start forming
use a ring mandrel and a nylon hammer first
after forming the ring you can use a ball peen hammer to make the dimpled texture , polish the inside I polish my rings by hand using different grit sand paper and polishing clohs
done :)
