Gordy,
Thanks for the E-mail message. I haven't posted recently not
because of anger or disappointment but simple because of lack of time. I
have been thinking about subjects for further discussion which should both
make some of the ideas more apparent as well as pushing the general subjects
forward. I simple haven't had time to do it.
My next venture will be to discuss in some detail the 4 paradigms of high
performance casting - I mentioned these in the prior write-up but didn't
elaborate. It's more feasible to explain these because of Guy Manning's
photographs and because the ACA site has video that can be examined frame by
frame. These help to explain how things can be accomplished in casting
and a separate subject I was intrigued with many years ago which is
an explanation of exactly what Lefty Krey does with his back casts when false
casting long lengths of fly line. Also it will lead naturally into
my approaches to teaching casting which I will discuss.
This will be integrated into the prior write-up as well and available to
the board. I think I'll prepare two documents - one with the new
material because it will be shorter and another which is an integrated
presentation that might be useful for historical purposes.
The new material will also contain a separate section on the equations
for rod loading and unloading. This is because these equations highlight
a surprising feature of rod behavior which explains some of the observed
behavior of fly rods.
I appreciate your interest. Walter has been making
important contributions in rephrasing statements and this is very important to
improving the acceptance of the various explanations. I look for and
appreciate Walter's continued help in these matters.
I can't promise when the new material will be available because I just
went on my first fishing trip of the year and have more family related
activities that we are scheduling for the near
future. Walter's and your interest will however inevitably heighten
my urgency. Be assured I hold no ill will in any way to any board member
and intend to continue writing (as well as reading) board postings when the
current rush passes.
Best regards - Server
Hi, Server....
I have been studying
your former messages from "behind the scenes" and having messages of
discussion with Walter Simberski.
Walter has shared some
of his thoughts regarding the physics behind what we have loosely been
calling "the stop". He has helped me understand these
concepts.
Although I'm not a
physicist or engineer, I'm beginning to get a much clearer understanding of
what you have proposed to the point that I cannot find fault with your
reasoning.
The concept of
suspension of acceleration rather than a true
"stop" ( which would be cessation of all motion ) has generated a
spark in my brain.
At the same time, I
understand the acrimony produced by others venting their vehement
disagreements. I came to the conclusion that this occurred largely because
they couldn't understand what you were proposing. I also understand
that you "bristled" because you couldn't come to terms with their lack of
comprehension.
Walter and I feel that
your paper on this subject is needed and timely.
We must realize that
even casting instructors who are educated may not even have had a basic high
school course in physics. In deference to them, I think it would be a
good thing for you to try to distill the concepts down to try to fit it into
plain and simple terms ..... NOT easy, I realize !!!!!!!
Perhaps this could be
done as a supplement to your paper ????????? .... Walter and I will help in
any way we can.
Best,
Gordy
