I recently made a guillotine style (hinged) fuller which used a socket
head shoulder bolt as the hinge pin. It broke on me today, right where the
shoulder ends and the thread starts. I'm going to try one more time, but
this time try annealing the bolt so it is tougher and less brittle. Can
anyone suggest a method of annealing? It's just a little part, so any
method would work. (Spoonful of molten lead?)
