What I was wondering about was tracking a tailsock surface with the DTI
secured to the carriage.. longitudinal travel of the carriage, but kinda
limited to one side of the carriage at a time, and only if the tailstock
ways are in nearly perfect condition.

Then again, I don't know if this check would reveal anything significant,
just pondering.

Good idea

And how about running the DTI along a precision tailstock surface, not
associated with the carriage travel?

You mean, keep carriage in place and move the tailstock?
