Progress

Ideally one should be able to bulk up the metal as easily as one can draw it out, but the difficulty is that one must strike the end of the metal to bulk it up or 'upset' it and even a minor deviation in the hammer blows quickly causes the metal to deform off to one side or another and getting an even fattening is a challenge. Drawing down is a lot easier as the side of the bar is the target and small errors can be corrected because many blows are required to produce a gradual taper.
The drifted hole in the rebar isn't visible here, but the bar is on its hook 2nd from the back.
