Mirror Wars Episode II



Hi guys,
  I have just returned from a ride after fitting a second brace design
to the windshield.  This time the ST lost.  The new brace eliminated the
mirror vibration all the way to 100 mph and after 100 mph the vibration
was only slight and quite tolerable.
  The new brace is made from a piece of aluminum "U" shaped extrusion
formed to fit over the trailing edge of the windshield just like the
original rubber trim piece.  This significantly strengthens the
windshield and fairing wings and stops the transmission of vibration to
the mirror mounts.  The aluminum piece I used was 3/8"x3/8" extrusion
for edging plywood.  A 1/4" piece would look better and be easier to
form.
  Now, the bad news.  Shaping the aluminum by hand is an extremely
tedious process that could be made simple if one had a bending machine.
I held it to the windshield with a piece of rubber non adhesive
electrical tape placed over the edge of the windshield and the "U"
channel pressed over it.  It seemed to hold on fine, but I'd hate to
have an aluminum boomerang come off at 100+ mph right into my face!  A
production fabrication company could shape these and make a decent
adhesive attachment system, but it is beyond my means.  If someone from
Triumph is reading this please consider a production design like this as
it would make a lot of ST owners happy.
  Another solution to the problem would be to have increased thickness
windshields produced as this would effectively stiffen everything as
well.  A change from 1/8" to 1/4" should do the trick.  Once again,
totally beyond my capabilities, but maybe someone out there knows of a
place that custom forms Lexan plastics?  Once again, Triumph, are you
reading this?
  So there you go guys, a solution to the problem but beyond a home
fabricator's capabilities.

Dan
