there was a guy on a VW forum who cut his whole wheel off due to a broken bolt. tool muppety exsists. i teach RM in a school. i have seen a kid try and glue 2 pieces of wood together with Cif surface cleaner.
I swear people should have a licence to own tools.
I've seen house electrics where people have gone through a wire with a 9 inch nail to hold it down, which also happened to be touching a copper pipe.
I've seen earth pipes for toilets DIY plummed in with the slope going in the wrong direction and the owner wondering why the toilet was backing up lol.
I think some of those are trolls, but the welding the diff up; if it was true, that bloke should not be allowed near a welder.
