Although not any where as sophisticated, here's a picture of an octant I made some years ago. I got the impetus to make this 'instrument' after receiving a copy of 'Latitude Hooks and Azimuth Rings' (subtitled How to Build and Use 18 Traditional Navigation Tools) by Dennis Fisher. I also made the nocturnal shown in the book.While playing with the clever visual search engine at searchme.com, I came across this web site which offers instruction to build your own metal micrometer sextant: http://www.geocities.com/richardandtracy/SextantPage1.htm I don't recall seeing this discussed on the list before. Also, if you've never seen them, there are a couple of nice plastic sextant projects described on the web site of Omar Reis here: http://www.tecepe.com.br/nav/XTantProject.htm -FER
