And if you put the two counterrotating wheels on a mount that could
spin in any direction (I forget the name for this - three circles
where the mount between one circle and the next, or between the
outermost circle and the outside world, allows spinning in one of the
three spin axis), then that would insure against any manufacturing
defects that did introduce gyroscopic effects, and possibly allow the
wheels to be moved. Though you might have to put each wheel on its own
mount, since the wheels might want to twist in opposite directions in
reaction to their mount moving.
Then again, with this mount, you might not need the counterrotating
wheel at all. The outermost mount doesn't turn relative to whatever
it's mounted in, and everything inside is free to spin however it
wants with respect to itself.
