Re JB Weld:
One thing folks should realize is that, while it has "pretty good" tensile strength, in my experience is has lousy shear strength. Significantly worse than most epoxies I've tested. I suspect that's because of the steel filler particles. It's great for filling holes (exactly what it was made for) and certain mechanical repairs, but it's a very bad choice where 2 parts will have heavy "sideways" pressure applied. (Unless there's a LOT of mating surface area)
That's my experience, anyway.
I think that for reinforcing with screen, or fiberglass, or whatever, it wold be an excellent choice, & I probably WILL do that on my saw, since there appears to be lots of room around that part.

The "Marine" JB Weld is intriguing, I never saw that before. However, I suspect that it's just "regular" JB Weld in a different packaging, to go after the System 3 market. ($$$$) It is the same color, and has exactly the same cure time & tensile strength.
- Like "Plumbers" "Household" and "Automotive" Goop. That's all exactly the same stuff.
But who knows?
