Hi Gordy,
I guess I was going to say that I didn't want to belabor this point -- but in truth I guess I do. The world of fly casting would be better off if the term "hard stop" had never been invented. It puts a real crimp in any credibility when viewed from a scientific standpoint. In most distance casting a hard stop is never even attempted let along achieved. But to go into that I will have to explain some real Casting Physics and I don't have time right now because I have to go to my office and prepare an hour exam on rigid body dynamics. Just a few notes to tickle your interest however. 1) -It is abundantly clear from expected structural dynamics and any available data that considerable positive work is performed on the rod-line system after maximum road loading occurs. All this translates into additional flyline flight speed (a primary goal in casting). 2) there is plenty of discussion flying around concerning casting analyzing data and its too bad noone has taken any kind of examination of the information. When I saw this data the first time a few years ago it largely confirmed to me noone performs hard stops as well as why. As a little challenge to any readers take a look at the data with my statement in mind that it clearly shows no stop at all is occurring until all rod vibration has been absorbed by the casters hand. Part of this is almost a necessity from physics -- not understanding it reflects just that weakness. OK so the analyzer developers didn't interpret what is going on -- the data demonstrates the rod continues to rotate in the direction of cast long after rod unload starts and in fact after counterflex (thanks again to Jeff Wagner for that term). Again the most critical phase of this is completely what one would expect -- because violating it would create large rod vibrations. 3) folks trying for long distance casts using choreographed casting motions are using what I term "Base Motion Augmentation" to increase the work performed during the real casting phase. To explain this I would have to explain some real physics. The high speed data is from that type of cast and performing this type of cast depends on maintaining as high as possible a translational rod butt velocity throughout the cast until the line is in free flight so there cannot be a stop at all.
More later. I sent another note explaining some things about line physics and aerodynamics effect on flylines but it may be that when I try to reply to everyone my E-mail doesn't go through. Did you receive that message?
Thanks again for maintaining this informational web site - Server
