I neglected to mention that I already do most of that, except the wood sanding block part. I havent tried guiding the router from an external edge, the bit I have is 1/2" HSS with a edge guide that uses the shaft itself. I'm looking for some sort of a bearing arrangement that could clamp over the shaft, and then some sort of sanding device that would work on a rotating shaft. I saw something similar in a Woodenboat, it was a sparmaker using an electric motor and a drum attachment, with an inside out sanding belt. On a smaller scale, perhaps a sanding drum attachment chucked into a hand drill? Then I need some sort of drive to turn the shaft... Like a lathe only without the head chuck? Just rambling...
