Have you seen this page on Cumpiano's web site? Bolt-on version of his neck joint: http://www.cumpiano.com/Home/Articles/Special%20interest/headblock.html
As for other books, are you planning on building lots of guitars, or just a couple for yourself? Ervin Somogyi's books are excellent (and no longer mega-expensive, thanks to Amazon) and go through the building process using molds, although he uses a permanently joined neck, and glosses over some of the more basic things that books like Cumpiano's will hold your hand through. But between the two of them and that web page, you should have no trouble putting together an instrument. And Somogyi volume 1 is worth its weight in gold if you're looking to dig deep into designing your own guitar shapes and bracing layouts.
I think there are some other good steel string how-to books as well, but I haven't read any of them myself so I'll leave that to others to recommend.
Oh, and welcome to the forum

I'd love to see some of your violins too. One of those was going to be my first self-made instrument, but then I got sidetracked into guitar land so it's still sitting there half done for the moment. Gotta get back to that one o' these days
