I need to re-build a cupola for a weathervane and want to make it functional so that the weathervane actually indicates wind direction. The problem is, I'm not sure of the mechanism needed to do this. I'm thinking of getting two bearings that I can add to the weathervane support rod, one at the bottom and one where the rod comes out of the cupola so that the weathervance can spin in the bearings. The bearings would sit in a pocket drilled in a wood support. Does it sould like this could work or is there a standard way of doing this?
