Thanks for the kind welcome, Steve. Puppets...well, it's just another one of those "out-of the-box" ideas that might provide the arena for learning to carve, to construct simple-to-complex mechanisms (anyone familiar with Czech marionettes?) and to provide some entertainment and "give back". Sometimes my ideas bomb, but that just means I have to get busy again
I'll be sure to get myself over to the intro section (and others, as time permits), but I may have to first take a lengthy detour in the cast iron category. After a very brief look about here I've found plenty of ingenuity, skill and a passion for simplicity...wow. Looks like everyone here has encyclopedic type knowledge and abilities. Just fantastic. Your stepson is extremely fortunate to have his family. (Insert emoticon for "truth"...) Thanks again for the warm welcome, much appreciated.
For now, back to the research
