If it is a small enough lathe - I would just take the tail stock off to home.. (that is what I do on the emco)
Have a cam style follower. So it home somewhere halfway down the travel. (so most of the time the tailstock is out of the way. (if it is past the trip point - it will home the other direction) Then have a switch on the tail stock that acts as an overtravel.
