Propane to fix cracked rack?

[merlinmurph]

Regardless of how you try to fix the crack itself (weld, JB, etc), I would also fortify the joint externally. Someone mentioned fiberglass or carbon. Maybe figure a way to get PVC T-joint pipe around it and glue everything. Or some combination of those.

Still, do what you can externally to the joint. It has already been compromised and will probably never be as strong as it was originally.

I tend to over-engineer things like this.....
