No way in hades I would trust anybody's epoxy on that thing. Now, if you know someone who can weld it up and start over, then that's a different story. Wall hanger.
The problem with welding that much of the port is all the moving and shrinking you'll get. It's hard to control and even if you are careful and keep the heat even you can still get cracking in weird places. The flanges will pull way out...I've seen .060 and the guy was careful.
I use an epoxy I get from Brownells. It's never come loose.
