I found a great site for sketchup woodworking tutorials. I was about ready to give up on SU myself...until I found this guy.
Wow.
It has helped me tremendously. No kidding.
I don't know him, but he seems like a good guy. The rest of his site is pretty cool too.

I hope this is as much of a help to you all as it was/is to me.
