The adjustable tail stock poppet, with the bench-screw holding a live-center

 

I have had good luck with a sliding poppet and live-center mounted in a turned bench screw on my treadle lathe. For the work involved, I think this design is easier to build than the one shown in Lynch's drawings. I still need to turn and install a handle. I drilled and reamed a morse tapered seat for a live center in the end of the threaded shaft of the bench screw.
