Good info here, but don't forget (as much as I like it and think it's an invaluable resource), Melvyn's book assumes that you have some woodworking knowledge under your belt. The 'woodworking' can be some of the hardest stuff do do if you have no tools or experience. Your body needs to be flat, your neck blank square and flat, etc.
As others have mentioned, I definitely recommend trying things on scrap first, make a (relatively) simple bolt on like a Tele, and GO SLOW! It would make sense to buy guitar body and neck blanks, as opposed to raw lumber also, especially if you don't have access to decent tools.
A router is important, but read up on it before you use it. A bit spinning at 22000 RPMs can do alot of damage! There are great how-to books on routers and woodworking in general out there at your library. I suggest you do alot of reading before diving in.
And, GOOD LUCK!
