In Response To: Curious; Where did the NESA receivers crack? (Craven morehead)
I am no welding-metal guy, but from what I have been told, the NESA receivers are a cast, made from powdered steel[?].
All three are cracked in the middle of the receiver, from top to bottom.
Three different [very experienced] welders tried various ways of pre-heating, then welding, slow cooling with an asbestos blanket, nothing seemed to work.
You could hear the cracks forming as it cooled, ever so gently.
