Instead of working on the race car brakes this afternoon I made a mockup
of the basic
Hensley Arrow mechanism - just to convince myself that retirement hasn't
totally removed my ability to think in three dimensions!. Guess what? As
expected the trailer has total freedom to swing! The secondary platform
can also swing. So it comes down to - "What are the secondary bars or
links? - I don't mean the load equalizers.
I suspect that it is a sway reducer not a sway eliminator - not that
that is all bad.
Anyhow I have emailed Hensley Manufacturing asking them them to send me
a copy of Mr Hensley's patent AND to email the vintage race list with a
decription of HOW it works.
Lets wait and see.

WHY NOT - WHAT STOPS IT?
BOTH THE ARTICULATED LINKS AND BALL COUPLING PROVIDE ROTATIONAL
FREEDOM.
