Tailstock power feed - video

[Toolmaker51]

Sensational!
Built-in feature of many larger turret lathes, non-existent [FAIK] on engine and toolroom lathes.
Yet certain types of work, it'd be a welcome addition.
So we did.
Drilled/ tapped edge of carriage and tailstock, threaded in screw hooks, stretched length of chain to hooks, engage carriage feed. Included big lathes, so big a crank moves tailstock.
There, saved folks 27 minutes. And a few bucks in material.
