how's the strength of reworked rebar (rerebar?)
Remember when those new bolts you bought cheap sheared off when you tightened them by hand,about that strong:-)

How I am wondering long a straight section is needed to get it started into the machine?
It's rotary swaging. Instead a simple closed die, using 4-5 individual sets. Same idea as wire roll straightening. Enough to reach first hammers from the opening, as this is fairly small rebar.
