I’m afraid I’m a sucker for books.  I’ve just ordered ‘The Lo-tech Navigator’ and the only reason I’ve not ordered ‘Latitude Hooks’ from Amazon yet is because I can remember needing a ‘less than £10’ item the other day, but now I can’t remember what it was.

The ‘Maple’ sextant looks great.  It took me a while to realise that ‘Maple’ was the wood and not the name of the maker.  It looks like you could market it as a kit for children 10-15 or granddads 60-100.  You’d just need a source of maple and some sort of laser cutter.  I don’t know how much the maple would change shape with moisture content.  A few coats of varnish would probably stabilise it.  Do I take it that you can print the book for the price of 122 pages of A4 and the ink?  It looks like I’m going to have to print it off to go with the other 100 or so books I have on my bookshelves waiting to be read properly in my ‘old age’ (and not a War & Peace or Don Quixote among them!). I love this idea. ‘The Vernier scale should not go edge to edge with the degree scale, but rather overlap it on a tapered ramp.’  I wish I’d done that with my ‘birch ply’ sextant.  Have you spotted within the text the link to the CAD arc drawing programme the author talks of?
