I have several Singer's, and yes, prior to 1960ish it was hard to kill a Singer. I have a cheap Taiwan replacement treadle base I was thinking of converting. If it works I'll let folks know.
In 1960 I saw a sweat shop full of foot powered lathes in Hong Kong. They consisted of two pedals which were pumped and a cord wound around a bamboo drum between bearings. this resulted in a forward and backward rotation. They had a screw chuck on the headstock end to which they mounted ivory blocks. They were turning ivory balls, the type with several balls within a ball. I bought a chess set that had each piece mounted on one of these balls.
They used a small scraper which cut on both the forward and back rotation. They could cut a ball out faster than I ever will be able to do with a Oneway.

In any case I believe you could easily make a small pen lathe, You would need a spindle with a morse taper and threads,so the old method of using round stock for the spindle won't work for pens.I have not turned pens , but I imagine the least you need is a morse taper spindle. You can get parts from Grizzly or many lathe manufacturers, ask for replacement parts.Might be cheaper to buy an inexpensive lathe and power it with the treadle.
