I look at building a pocket size Sextant?
Most are 3" [75mm]? to 4" [100mm]??
I decided to build a little bigger for easy it about 5?" [138mm] x 5" [125mm] . Using a off shelf protractor.? This to save time over making a protractor.? I found a WEN PROTRACTOR easy to repaint the numbers.?
The mirror doubles the number.? Basically if The mirror moves 90¡ã it would only read 45¡ã. So need to renumbered to 90¡ã.
