Interesting..
You have lot of time, right?
Then you should.... Read!
Melvyn Hiscock - Make Your Own Electric Guitar
Martin Koch - Building Electric Guitars
There are other ones, but if you're going to buy 1, get the Hiscock book.
Noodles of information.
Either that... or... study hard, become rich, and hire people to make custom guitars for you.
Jk.
