From Ally Gowans :
Hi
Gordy,
The earliest reference
that I have so far found relating to the D Loop is in a video called ?Advanced
Salmon Casting? by Peter Mackenzie-Philps copyright 1984, Michael Evans also
refers to it in his video made in 1992 so it looks like the term was used as
long ago as the 1980?s and maybe much earlier and that it possibly originated in
the UK.
Best
regards,
Ally

CONSERVATION
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Hi Gordy,
Greetings from south Louisiana, Your friend Rick Williams and I have taken
over as volunteers the Conservation Coordinator role for the FFF. We plan
to split up the work and continue FFF's conservation work, grants,awards,
position papers etc. Leah Ewell FFF's Conservation coordinator, resigned in
early March.
Rick asked me to help him keep FFF's conservation work moving along until the FFF could find a replacement. ($$ permitting!) So, if you have any pet conservation projects perhaps we could help it along through the system.
Will be
teaching roll casting up at the GCC's EXPO in New Braunfels, TX in early April,
Hope you are enjoying the beautiful spring weather, Bob

CASTING MECHANICS - Leverage
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Jerry Puckett asks a question :
|
Gordy,
How would you explain the relationship of fly rod leverage to
translation and rotation?
Is there any leverage with translation or is it mostly
rotation?
Thanks,
Jerry
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Jerry, To me, it is obvious that leverage is needed complete with all the elements of a lever including a fulcrum when the fly rod is rotated as it is during the casting arc. What is less obvious, is the use of leverage during pure translation (linear motion) with no rotation at all. An example would be the translation of the unrotated fly rod during DRAG used prior to the application of casting arc. I gave this quite a bit of thought and came to this conclusion: Let's assume that DRAG is accomplished with perfect movement of the rod in the direction of the cast in such a way that there is no rotation at all. (A theoretical situation, since most "draggers" can't actually make that move without at least a tiny bit of rotation.) In order to do this, the caster must at the very least tighten the muscles which support the unrotated rod as it is moved through translation to maintain the original angle between the rod and an imaginary horizon (actually water or ground.) That very act requires leverage. Without it, the rod will flop to an angle in either direction. While we may break down the casting stroke into its component parts including translation and rotation, for teaching purposes and in doing so look at the casting arc seperately as the angular change in the position of the rod from RSP to RSP, in the real World of fly casting, for almost all casts we actually have a variable admixture of translation and rotation existing within that stroke. That mix of translatory and rotatory motion will likely differ with each caster if not each and every cast made. This makes it even more true that we use leverage throughout the casting stroke.
