TSA, What he showed me was pretty simple. Once the two ends was folded over real close, just so you could see light between the gap, I filled the space with Borax. Then put it back in the forge till it was good and hot. Then started beating it from the middle , out towards the edge. Anyplace you could see light between the two pieces was filled with Borax, reheated and the process started over again until there was no light between the two pieces. Once it was welded then I reheated it and started to draw the blade out.
