There is a good article in the latest "Home Shop Machinist", available now

work on a South Bend. The exact reference is:

"An Automatic Carriage Stop for Thread Cutting" by James McKee M/J 05 HSM

If you want something that will prevent power-crashing the carriage into
the chuck when powerfeeding, then you need a limit switch setup, perhaps
backed up with a solid beefy carriage stop. I don't know where plans for
a limit switch setup are.

Limit switch is like on mills - you attach a block to the side of the table
and when it drives into the switch it turns off the motor. Likely an option
or a 'make it your self' option.

I never like the hard stop - in friction feed it works just fine - friction slips.
In geared drive - break a toot ? stall out the lathe - I doubt the later.
