Doesn't the Woodshop offer templates for you to choose from? If not, you're in for a Major Project, to say the least. My advice would be that if you are going to devote all of the time and effort taking on such a tedious and precise instrument, invest in the highest quality material available. Take your time and build it right ( make sure to have a complete schematic that you can add to or alter as things arise).
I like your optimism, it shows character.
Study every type of guitar that you can get your hands on and document your findings, all the way down to the location of the strap pegs.

Good luck..................

PS::::: Always remember;
"An Optimist is one who finds opportunity in every difficulty".
"A Pessimist is one who finds difficulty in every opportunity".....

Here's a complete description for all types of Individuals;

Optimist; = A person who doesn't have all the facts.......
Pessimist;= An optimist who has all the facts.............
Cynic; = A pessimist who has seen all the facts in action....................
Paranoid; = A cynic who just realized that the facts are after him.........

Last but not least;
Always borrow from a Pessimist, He doesn't expect you to pay him back.....
