I might also mention that I was quite impressed by a subsequent post that
stated that all that was needed to keep the work straight was to keep tension
on it and it sure makes sense. So if you can tension the work then there is no
need to use a pipe (as I suggested) to keep the work straight. All of which is
born out by observing a pair of wires being tightened tourniquet fashion.

This exactly how safety wire pliers work. The two wires are gripped,
the pliers locked and the knob pulled. The knob is on a spiral rod so
that both tension and torque are applied.
