John D Howard you said: With a little skill and time I am sure a handy person could build a sextant to one minute arc.
It is possible. You really need a lathe with a dividing head and a technician to get you started for both the arc and the vernier. I'm afraid I rather rushed the vernier, and 35 years later, I'd need a lathe, another instruction session, and a lot of patience to do it again. It was a kind of "Done it. Got the tee-shirt" sort of a thing. I make the reading 67 degrees 46 or 47 minutes. DaveP
