I note in reading the two descriptions of making Stub Twist, they do not read the same. Greener does not say the stubs were "Melted" (puddled). They were according to him brought to a welding heat where they bonded together. I am thinking just perhaps the later writer may have made somewhat of a mistake in his description, I do not believe even the stub twist bbls were puddled, but the seperate pieces were simply welded. With modern welding technics the metal is normally melted at the join, but not so with forge welding. It was brought to a very high heat, but slightly below the melting point & when parts touched they would actually stick together & join at point of contact. The hammering was to insure full contact & help force out slag etc.
