For my friend computer retorfit I had a chassis for a computer cut to size. some of the holes for the mainboard mounting bolts were cut in half. I JB welded the mounting nuts which normall screw into the threaded hole that was cut, and it is solid. so slid in fact, that I am pleased with how strong JB weld actually is.
Years ago my father had a 1969 rolls cornice. The intake manifold cracked. We bought some JB weld, and Took off the manifold and JB welded it back together. The repair was excellent and lasted quite some time. My father and I did not actually do that repair, but we had a mechanic do it, as were were on a road trip and just needed to band aid it.
We drove home, no problems. My father took it to the mechanic at home, and well he looked at it and said no need to repair or replace it, the JB Weld has fixed it. We were surprised, but we never had a problemw with that car again. my father sold it a few years later while in the middle of restoring it to someone. The person to this day still has no issues with that intake manifold. We happened to bump into the guy randomly, and the car is still going strong.
The Rolls was alsoa right hand drive. Funny story on how my dad bought it. We were having a garage sale, and this lady pulled up in the car to look at what we had at the garage sale, and well my dad bought it from her.
