I spent the afternoon setting up a 000 style acoustic which a retired friend of a friend has built to take out to his son, who lives in Spain.
Though he has considerable experience as a furniture maker, this was his first guitar (incidentally he's a non-player).
He bought Jonathan Kinkead's book - which contained the plans - and a detailed explanation of how to tackle each element. He used a solid cedar top, mahogany back and sides and made the neck out of mahogany from a 100 year old wardrobe.
I cut the nut for him, set the relief and guided him through trimming the saddle.
It now plays well and sounds remarkably good (I'm a big fan of cedar/mahogany).
Really enjoyed helping him make the guitar playable - but most of all struck that a complete guitar building novice has built something which sounds so good. The materials are freely available - may be it proves great design works?
