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.

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 (23 years ago, 10-Mar-01, to lugnet.space)
