Maybe Gordy can help me in finding the video where he casts a rod without a line. Merlin, Here are the measured butt angular acceleration and perpendicular tip deflection profiles that were measured for the inertial loading of the rod with no line. You can click on the full screen arrows next to th...

And changing pull angle might well change the picture. Merlin, Since haul speed is related to the derivative of the distance between the first stripper guide and the haul hand then changing the direction of the haul relative to the stripper guide position should have an effect on the haul speed. Th...

I’ve used epoxy resin putty covered with an outer sheath of shrink wrap before. Graeme, It is great that you have the inventive spirit to come up with a grip shape that works to reduce the pain you were having with conventional grips. How do you apply the epoxy resin to increase the size of the gri...

I was doing it to modify the shape into something more ergonomic for me, Graeme, Could you show some pictures of what that "more ergonomic" shape looks like? I know that Chris Korich recommends reducing the diameter of grip in the region where the ring and little finger grips the rod. Tha...

Thanks Merlin,
What do you get for the linear fit to that data? It looks to be the same as Hoffman's.

Merlin, If I have done the conversion correctly your k1 spring constant for small deflections measured in g/cm can be multiplied by .982 to get the standard N/m spring constant value. I.e., the two dimension choices have nearly the same numerical values. To compare your recommended spring constant t...

that pellet has dropped 3.2 ft in those 100'. Most folks think it only falls maybe an inch or so, or at least that is what I thought. You may have calculated the velocity ( -3.2ft/sec ) in your calculation, not the drop in distance. Under a constant acceleration of -32 ft/sec { ^2} the distance an ...

I didn't track it through and both the travel and propagation curves (which are of the hauled loop) on that plot are calculated. Dirk, Does that mean the travel speed curve (loop velocity over the ground) was equal to 1/2(v1+v2) where v1 was equal to the velocity of the fly leg and v2 was the rod l...

why do physics classes dedicate so much time and effort to the study of conservation laws if they are not applicable to real life systems? Walter, My experience was just the opposite. My dynamics professor warned, " If you ever use conservation of energy to solve a problem that has an outside ...

A check haul would put a stop/start into the overall shoot and I’m sure the resulting distance would be less. Paul, I have observed that Steve Rajeff and Cris Korich will sometimes stop the shoot of the fly leg near the end of their competition shooting head casts when they sense the fly is not goi...
