Thanks a bunch, Charley. I got a question a couple of days ago relating 
the possible impact damage by a freely swinging piece of suspended 
machinery. The site provided me with exactly the info I needed to explain 
the problem with minimum armwaving. 

And Roger's 18 inch back bar sliding is a great illustration for these 
guys--they think I'm just trying to make their lives difficult with a 
restraint at the free end of this thing.
