I'm finally at heat treat and I can't get it to work. Map gas torch, outside, windy. I can get one small 1/2 section non magnetic and try to keep going up the blade but I can't keep things hot. I get the one section done, keep going and even if I come back the start is back to magnetic. I wanted to do the full blade but realize that it probably isn't going to work. I spent an hour outside trying and just couldn't get it. Tried the spine to edge, edge only, half way up... I hope that I haven't ruined the blade as I had scale forming. I have pics that I will try to post but firm some reason they won't email. Any thought/help would be appreciated.
