Don't be like my neighbors? I have an AC adapter I just got to find it. I think i'll be in the shop Monday doing some more of this Robert if you want to stop by.
Mook, I used mild steel for the bun and 1084 for the dog. I am thinking I might have to go higher carbon like W1 or W2, to account for any migration that occurs.
Gresham, What part did you want to play through, the forging to shape? Sorry for lack of an explanation, basically it was put a groove in the mild steel, then bang in the good steel piece to fit in the groove, then forge weld it all into one piece. I did not weld the insert piece cold, I fit it in then compressed the steel around it to hold the piece in, then took another heat on the whole thing and forge welded it.
