These homemade rack will never, ever, hold much weight side to side due to simple inertia.
Any weight in motion wants to stay in motion. The metal AND THE JOINTS are not rigid enough
to damp & supress the inertia of a side to side load. This is where welding can win the day.
IMO these racks are more of a danger and trouble that they could ever be worth from a simple
engineering stand point. For this application it's welded rod or forget it.
