When you employee bushings for any reason when dealing with a bolt, are these bushings "welded" in place or "threaded" in place? I watched a video where silver solder was used. Is silver solder strong enough to use on bolt faces?
Silver solder gets the bolt head way too hot for my liking. I prefer a pressed fit using a good retaining compound like LocTite 609. Once it has cured it is there to stay.
