Vince, I mentioned that I was building a bookcase. Here it is:

This is typical frame and panel construction. The only man made material is the back. I recommend doing frame and panel when working with construction lumber. It avoids a lot of issues (not just with pine, but all wood) which is why the old timers used the method in the first place.
I have about 35 bucks in it. A nice pile of scrap from the resawing that will be useful for other small projects.
This is built with mortise and tenon construction.
