Neat. How did you arrange the 'advancement' of the bar?
I presume it was a single bar per setup, rather than a
stack of bars which fed in sequentially. You must also have
had some 'enclosure' for the part of the bar sticking out
the left side of the headstock - to prevent it whipping.

Did the finished part just fall off and remain where it lay,
or was there a 'collection' mechanism for the finished parts too?
