Prometheus:

Thanks for the feedback. I forgot to mention in the previous posts
that the next version of the contraption will have mirrors at the
bottom of the stand to show you what you have just cut off relative to
the marked circle plus electric fans to blow the chips away from the
mirrors I had thought about hanging something from the ceiling or
attaching it to the walls but those ideas did not seem workable so
went with something to sit on the floor. Thanks for pointing out I
was working harder rather than smarter. Chiseling or shaving a flat
spot on the round side of the log is obvious in hindsight.
