I clamp the frizzen lightly with vise grips while heating the sole face with a soft flame on my acetylene torch till a nice cherry red. I believe Nick has a better idea of tig welding the new face material and will use his approach for soleing future ones.Here's a dumb question for those smarter than myself. If hard silver flows at about 1400F, and steel goes nonmagnetic at about 1400F, how does one harden a freshly soled frizzen that's been silver soldered? Is a lower quench temp ok, or is a different higher temp brazing material used, or something else entirely?
