i have some experience in fire welding and obviously some welding situations r easier than others. What i like doing is to laminate cutting tools of all sorts. just makes sense to me to have the edge steel only where it's needed, even if we can afford now anything in our blessed, wasteful times.
Now to my problem. Usually i weld the steel to one side of the blade. I put the tool into the fire ,so that the steel bit lies on top and will get less heat than the low carbon tool body.so in a way, an ideal arangement.
But when I sandwich the bit in between, as with an axe head, i find it difficult to get the top layer hot enough without burning the other layers.
Is it a matter of building a bigger fire?
Any advice on that and indeed, fire welding in general, would be very appreciated. It is an ongoing challenge for me, the very core of the craft
