Roger,
This post had me doing some reconsidering also and the other day I took out my wooden HNT Gordon smoothing plane, fidldled with the settings and staring playing/attempting to smooth out a scrap 2x4. Well..um, at least it's a starting point for me and an incentive to learn more. I really need to go back to learning more about sharpening - which I always liked to do. There is something exciting (don't know why) about taking a plane blade or chisel from not so sharp to very sharp; I don't obsess about it, but it is nice. Nicer still to apply that blade or chisel to actaully make something. It's also quieter and in some sense a different mindset then using power tools.
I am not going to kid myself and think about flattening table tops, cabinets, dimensioning lumber, etc., but I will be picking up and using my planes and chisels more than before. One note though regarding planing vs sanding. Using my sanders and vac, there reallly is virtually no dust to deal with and shavings to clean up.
Anyhow, I think it's a great idea to take a class. I was at the Woodworking in America show a few weeks ago and regret not attending any of the classes - flattening wood with planes, drawmaking, etc.
