Suppose I have a Acme threaded rod (otherwise known as a lead screw) and a few nuts... I want to have one nut in a position and frozen in place so that it can bear against another surface... but other than locking two nuts together, which proved to be unreliable (one nut moves and defeats the whole lock system) does anyone have a better way of freezing a nut to their thread? Some mentioned welding but I don't have a welder... do you think those bandsaw blade brazing strips will work? Another idea I have is drill/tap the nut for a set screw...
