[TheForge] informal heat treat suggestions

[Peter Fels And Phoebe Palmer]

Hi Grant M:
I wrapped them around a tapered H13 mandril in a tight coil; 
removed...heated as evenly as possible and stretched the 
coil....then spent way too long fussing around to get them closer 
to right.
The reality is that they can be pretty funky and still work
The tapers were forged out the old fashoned way...used my old 
pop-up torch for quick, localized reheats. The blunt end was 
roughed into a ball on the anvil and flattened, then punched.
That cover it?...Pete F
