Sheet metal design resources?

[Inverted Vantage]

So it seems to me that the cheapest and easiest way to make mid level production of fuselages is via sheet aluminum. Unfortunately, I've spent all my time studying composites and their construction. I was wondering if there were any places I could find that gave general do's and don'ts, what is easy and what isn't, etc, of sheet metal?

Thank you.
