Just some thoughts, drawing and (hopefully good) results forthcomming

Good suggestions.
My thought on welding is that it will be hard to do without damage to the bearings and if the bearing survive the heat, I am not sure that the joint will be that much stronger -- the problem is the base metal gets pushed out of the way.
Pins are another thought. It may be that a pin in the middle of the rounds could take more torque without taking away more than they give. I think it would take an FEA to be sure as the loading gets pretty complex for pen and paper guys like me. Anyone up for an FEA optimization problem? How many pins and where to locate them to reduce the stress by a factor of 2?
PM me and I will coordinate efforts.
Thanks. Keep the ideas coming.
