Sort of stupid question about hardning copper wire. I'd like to harden some 10 guage copper wire for making an antenna.
Other than work hardening, are there any other way to harden it up? I've been thinking about coiling it up then unwinding and recoiling a few times. I do need it straight in the end. The jewelry people seem to think fully annealing it coppper first is a good way to get started.
Would running it back and forth through some sort of wire straightning jig with the ball bearings work if they're offset enough to zig-zap the wire for the first passes before drawing it though the last times to straight it all out?
