"good enough" to last out the warranty, probably. Wow, what crap! Not even a
cheap bronze bushing for a critical part?! Metal spinning in nylon will
generate heat too, even a microscopic imperfection will cause local melting
that will only increase, "positive feedback" style.

magnets! Surplus "disk drive" magnets, aka supermagnets. They might even be
good enough for installation, not just glue clamping. If your baffle was "L"
shaped so it couldn't tip over I bet 3 or 4 of them would have mounted the
baffle without glue or welding.

I know that sounds crazy but I think it would be a good permanent solution.
