So far, it looks good; I'm a little puzzled why there is a ring around the wheel. Is it to provide a rotational platform?

That ring will be used to mount the module to the lazy susan. As of welding, we hope to if we can find a location to weld at. We have not yet calculated weight yet, we are going to cut weight anter we build our 1st design.
