   2   I have not been running my  SMT8 style verticals for very  long so the
hinge contition has not had adequate history. I use an additional brass clamp
~.125" from the hinge(just enough to allow clearance from the perpendicular
clamp. The hope was that it would take most of the tension. Aluminum has an
oxide coating at the surface (which makes it hard to weld in an air
environment). Could this maybe contribute to the bond issue. From what I've
heard, if one sands aluminum that the oxide forms almost immediately.
