The guitar bug seems to have taken hold as I have recently bought a copy of Build Your Own Acoustic Guitar by Jonathan Kinkead. It includes full size plans for a steel string acoustic.
Going through the book, which gets good reviews, is clearly written and has nice colour pictures in it (check out the preview on Amazon), I could possibly tackle the Kinkade Kingsdown Acoustic (a Martin OM variant) to start with, which is the one he builds in the book. It's actually quite a handsome guitar although I do lean towards the classical and therefore nylon string guitars, which are of course different in style and in details of construction (having a integral neck for one thing). By the way, his guitars are called 'Kinkade' rather than 'Kinkead', so it's not a typo.
Having gone through the book a few times it all seems very straightforward - all I need to get are some (more) tools and I'm off! I've even found myself looking at second hand bandsaws and routers on ebay.... OK, maybe that's going a bit far.
