There is a whole world of woodworkers working without power, it's wonderful, creative, and beautiful. Jarrod Dahl is one of those woodworkers, creating his turnings by roughing out the blank by hatchet, then turning on a pole lathe, all his creations on his website are done entirely without electricity, something I aspire too.
His wooden ware is done in the Slojd tradition, as all his work is. I hope to be there someday in my journey.
Why not? The parts are easily replaced, no shipping charges, no electricity when PG&E turn off the electricity. And, he'll get in really good shape. One thing you might consider is a stationary bike and use those old web belts as they used to use.
