Herb,
I've taken the better part of the day (even at work ;P) reading through this thread and I have to tell you, it's truly inspiring. I'm just starting my woodworking shop from scratch and have lost count the number of your images I saves as reference.
I know how much you like to work outside. I'm going to build a stand like this one in my shop, and I bet you could easily wheel it out under the tree to hold several of your tools. This guy has his drill press and grinder stored underneath and swaps the tools out as he needs them.
I like your idea of working outside, and would use this if I could. I'm in a townhouse complex, however, and the HOA probably wouldn't appreciate sawdust all over the drive

I will likely need to come up with some sort of cover/shroud to keep the dust down. What tools do you feel kick up the most sawdust?
Thanks again for sharing all of your success with us so we can learn
