Oliver,
What you need is a good book. I have an earlier edition of this one.

http://www.amazon.com/Carpentry-Buil...2630811&sr=1-4

It is intended as a student's textbook. It's almost a thousand pages,
with many, many photos and diagrams. It will lead you through the
entire construction sequence and answer your questions. I highly
recommend it for anyone about to undertake building anything bigger
than a dog house. I don't make money if you buy it, I just think it
will help you.
