Bernie:    Don't you just love a good list dialog??? Your
points are well taken, and indeed, you are right; EMT is
plated steel (wot was I thinking?). I just was trying to
avoid cutting up the sheet metal, and it seemed to me that a
small spacer of hefty diameter would reduce or avoid cutting
and introducing rust points. As you say the lateral forces
are in the neighborhood of 200 lbs., so it seems that a
small increase in the length of the lever arm would be of
little consequence. (wL squared over 12 I believe.) By
welding one end and finding a way to leave the other end
adjustable but constrained against both forces, a much more
rigid solution would have to be the result. 

I believe that your solution is excellent, but I have always
considered EMT good for not much more than wiring and
hanging garage door openers. Also, I could not possibly
approach such a delightful project without gilding it
somewhat. I am sure you would agree that all designs can
bear minor improvement here and there. Also, you can
probably tell that my former profession as an Architect with
a specialty in structural engineering is getting
rusty......... And, yes, I do prefer silicon.
