Do you get by with the graduated markings on the barrel and the markings on the crank?
Have you implemented a poor man's DRO with a caliper mounted to the stock and barrel?
Is there something better?
Thinking about a trip to HF for a cheap digital. I'm making some stainless steel pen bodies, and drilling depth is modestly important. Since I plan to make several of them for both Space Pen (tm) refills,and for my own carbide scribe "refills" I'd like to be able to drill to depth quickly and fairly repeatably.
