 I think that


SNIP
is one reason they didn't use the EDDIE on the LeMans.  Also, using the
"Organ Pipe" approach you don't have to have tubes sliding inside of tubes
to keep the effect on the rpm {:>).

At least that is my take on it.  Could be wrong, have been before and will
be again.

Be seeing you in about 1 1/2 weeks, Charlie (provide the Wx holds good)

 What I meant to say about the Leman's and sliding tubes, it that I have
found if your are simply sliding a tube within a tube - not much of a
problem.   My experience is when you have two tubes - each rigidly
constrained at it's end that you are trying to keep sliding, even a very
small amount of angular/axial? misalignment can cause the tubes to bind.
The longer the tubes the worst the problem.  Perhaps I don't understand just
how they moved the tubes and they may have had the same problem - but could
afford the precision machining to overcome the problem {:>).  I'll have to
go back and look.  But they did not use the EDDIE.
