You might want to consider installing a Trav-a-dial on your
carriage.
It measures infinite travel, is always available, and is quick to
re-zero. It's one of the most-used accessories on my Clausing 5914.

I like the 2" indicator for threading, the micrometer stop for boring
a flat-bottomed recess. It's difficult to stop within 0.001" without
overshooting using the carriage handwheel.
