McCune Rocker Bogeys

Has a nice ring to it, doesn’t it?  These are images of one wheel assembly that will become part of a rocker bogey. Three of these support the weight of the entire telescope and sit on top of one each of the three piers.

You should notice that the wheels are not mounted on parallel axles, rather the two axles are canted in toward each other so that the wheels themselves will roll tangent to the azimuth bearing surface they support.

The plates that form the frame have a hole in them between the two wheels. That’s where the pivot shaft will go, hard connected to a set of support plates outside of the assembly you see here, cradling it, and giving the rocker part of the bogey its name. This drawing will help you visualize how it will look when the whole thing is put together.
