I did not check dimensions to see what size threaded rod should/could work.
 My main interest was in displaying the overall design idea.  I hope I did
not lead anyone astray with the information that is portrayed on the web
site.

In your particular application, if you feel you need a larger diameter
threaded rod (inner and/or outer) for stiffness purposes...please feel free
to modify the design to suit your needs.
