Hi all,
well i was thinking about trying to use a blow torch to get a smoother hamon on my differentially hardened 1095 blades. when i use the satanite clay i get a good temper line but it is usually a jagged line and not always predictable. I thought if i was able to harden with a blow torch like i have read in some Fowler books i might get a more even and smooth temper line. From my understanding i would heat the desired portion of the blade until it became non magnetic and then quench.
My questions would be how to test the non magnetic point , as in what kind of magnet to use
How long does the blade need to be held at this temp? (in my evenheat i hold 1095 at 1475deg for 5 min)
anything else anyone can think of that i might need to know would be very welcome, i plan on trying this tomorrow if it all works out
thanks
steve
