I've already tried Burns Stainless. They do not carry - nor will they make -
90deg bends in 321 stainless. They only have "U" bends and straight. I don't
want anymore weld joints than needed and cutting a "U" and welding in a
straight leg means at least 2 more welded joints than I really need. 

I haven't had good experience with welded joints - I want to minimize them
:)
