Folks, I would lie to be able to measure workpiece length while the

For a hollow tube a hook scale would work. If your eyes are good you
should be able to measure within a 64th or better with no problem.

How close do you want to measure it?

As close as sanity provides. Within a thou.


If you want cheap make up a hook scale without numbers and then depth
mike off the opposite end of it. Measure the length of the hook scale
and do the math. Or if you can put a straight edge across the back end
just use a depth mike.
