It seems to me that this approach might be a little unstable.  The
overall center of mass would stay in one place of course, but with
respect to certain axes it would be problematic, especially when
maneuvering.

Given that a rotating disc/ring/sphere would also tend to create a gyroscope
effect, I don't think this is that much of an issue. Besides, maneuvering
means even _more_ fuel you have to haul around. Get pointed in the right
direction, spin up the disc, go, spin down the disc at the other end and
do the fine adjustments to park the ship.

I was referring not to a rotating disc/ring but to a pair of pods
connected by a shaft, rotating about the center of that shaft.  The
gyroscope effect would be generated to some degree but it would be a
lopsided one.  My understanding about gyroscopes is that the effect is
related to the velocity of rotation, not the mass.  Is that wrong?
I'm no physicist, really - I just know that gravity generators are
unlikely.

Using a flatter strucure like an Omega destroyer or Leonov would work
similarly, I suspect.

Not familiar with those.

I'm thinking however that one could construct a ring of modules where
the modules connect to one another.  The question is, how can such a
connection be made?  Lego doesn't really have a way of making shallow
angle bends like that in a corridor.  If anyone has any ideas I'd love
to hear 'em.

I dunno, I think some click-hinge plates and some overlap in the walls might
work out for something like this.

I've generally avoided the Star Wars sets because of all the
non-standard color in them.  But I haven't seen click-hinge *plates* -
just the ones that are a pair of 1x2 bricks with a hinge connecting
them.  What sets have click-hinge plates?  What other kinds of click
hinges am I missing?

(...) I was actually thinking bricks when I wrote this, but there are 1x2 plates with click-hinges sticking out the top of 'em, on one half. Not sure which sets have 'em; I think I got some from one of the Life on Mars mechs. -JDF (24 years ago, 10-Mar-01, to lugnet.space)
