    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:

    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:

    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.

    The octant is made of 3/16 inch aluminum plate with paper scales.  Although not equipped with a micrometer, it does have a fine adjustment screw and vernier.
