I can envision what you're saying, but the devil can't catch me. However, all I see is a balanced system. Where does unbalance come from to cause motion? - Or is that not what you're driving at?
A good report on Egyptian bowls/drilling can be found at: http://www.geocities.com/unforbidden_geology/ancient_egyptian_copper_coring_drills.html
I believe the axle of the bowl you refer to is in fig. 15 on this page.
