Was kinda thinking. What about making a small L-shaped piece that will be a bit smaller than the width of the tab, and only maybe an 1/8in tall, and then JB Weld it as a support to that tab? JB Weld has like a 1500 lbs of pressure strength, right? Think that would hold up to the bashing of the ball?
I've used JB Weld on a project before, and gave it a good "trying to rip this out, without actually ripping it out, test." and felt like the joint was much more secure than the rest of the piece, and if anything were to fail, it would be right where the JB Weld ended.
Then as added security, maybe a layer of Gorilla Glue. So that if the JB Weld does crack and break into pieces. The Gorilla Glue will hold it in place. Don't want to hack pieces. But for something this small and out of sight, I'd like to avoid actual welding for the spots, like accidental mentioned. (edit: hah, realized that your username isn't actually LoopCombo. )
