For fun and challenge I would like to make some inside (french doors)
and outside doors, and some windows. I know I don't need to. I know I
will not save any money by doing it, but I think it would be kinda
interesting.

As always I started here by looking for books that would get me
started.. many people have asked over the years and few have gotten a
good answer.. so.. to keep the torch burning and in the hope that
things have changed...

Any recommendations for books on building windows? Books on building
doors?

Books... articles.. web sites.

Thanks in advance.
