RE: He could not believe the plans do not insist on a gusset welded to the mass balance arm to stop cracking failure.
He is most likely correct. Or you could use steel. For those of you who were not at the gathering last year, Jim Faughn had exactly this failure. He had it repaired while at the gathering and I think that he has replaced the aluminum arms with steel, but you need to ask him for the real story.
