Merry Xmas Colin
I used to use propane but couldn't get it hot enough and it took ages to get hot so it is wasteful too . If you get the temp too low you can still bond but it will be a poor joint . Liable to seperate ,the temp i'm doing them now is guaranteeing a life time bond . I've always wanted a a smithy forge so it's another excuse to do it . I have tried friction welding with limited success . Not saying it's impossible but again unreliable the way I did it . Really annoying when the cap falls off after building a mallet !
I also use my oxy-acetylene kit for brazing welding and silversoldering jewellery so I am pissed off I can't make anything over Xmas . Got a bottle arriving on jan 10th . I think BOC 's plant blew up or something a year or so ago , they haven't been right since . Forge will be great for separating brazed frames too .
