    Walter & Group :

    I see that some Group members were dropped from our address book.  That can happen if a number of our messages are returned as "undeliverable".  It's automatic and I don't get notified.  If I have to leave my MailList Controller for a period of time, I'll announce that in my final message before going away as I've done in the past.

    Let me know if you find that you stop getting messages for a period of time and I'll re-instate you.

    From Deb Bowen :

    Gordy I'm sorry to bother you but I have a question regarding something printed in The Loop - Winter 2009.  On page 35 under the section entitled "CCI Leader Math" by Jason Borger - I'm a bit confused on something printed here.  The last line on pg. 35 states that a 4X(.005").  Shouldn't that be (.007") for a 4X leader/tippet?  If not - then how could a 4X & 6X both be (.005") as is stated in this article?  I'm I missing something here?

    Deb....   Good catch.  Looks like a typo or misprint to me.

    Bruce and Gordy

     

    Below is a quote from an email I received:

     

    ” 3. Casters apply force and torque.   To me this is important, because many instructors insist on the term "power" to describe a caster's efforts.  Power is force x distance / time, and use of the term power in fly casting instruction is imprecise“.

     

    Force or power. Which is the more correct term when describing getting the effort required by a caster? We seem to use “power” within the program, but it keeps getting pointed out to me by engineers that the term is used incorrectly and we should be saying “force”. If “force” is the more correct term why haven’t we corrected that.

    Bruce Richards' answer:

    Hello Guy,

    Most people don't have a good understanding of what these terms mean, but

    know what is meant when they are used in fly casting. Force is certainly a

    better term to use than power in most cases. I'm not too concerned about

    how these terms are used by instructors, but if included in definitions or

    scientific presentations they should be used correctly.

    Power is the amount of work done per unit of time. ++Probably not the best

    word choice for most casting topics, but everyone know what is meant

    a force is that which can cause an object with mass to change its velocity

    +++++This is a better choice when describing casting motions

    a force causing changes in rotational speed about an axis is called torque

    . ++++torque is a force and most people don't understand it so probably

    not a good term to use except in scientific discussion.

    Comment:    I agree with Guy as well as Bruce.

    My answer to Guy's question, "Why haven't we corrected that"  is that most instructors prefer to avoid the use of the term FORCE because it tends to lead the student into thinking he has to work harder rather than casting in a smoother manner.  This despite the fact that he is absolutely correct that it is a more scientifically correct term.  I think that Guy is also correct that the use of the word TORQUE would lead to confusion when teaching non scientific folks.

                                                                               TICKING

    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

    John Wilson comes in with yet another fault which can lead to TICKING :

    Ticking is caused by allowing the rod tip to drop during the drift.
