I've really tried to find something online that's suitable but what I'm after is
I've two concentric circular rings, one of which has a diameter about 10mm smaller than the larger .
The rings themselves are in the region of 300mm diameter.
I'm trying to find a way to connect the two together and allow the smaller to 'slide' in a circular rotational way within the larger one.
I'm also trying to let the 2 rings pivot vertically in relation to each other - the intention being of producing a gyroscopic-esque motion.
What type of bearings/tracks/spindles would suffice?
