Re: Evaluating the Haul
There is something like a factor 2 by comparison with the record. Could you please plot speeds (rotation, translation and line hand). Many thanks in advance Merlin I made some adjustments to the acceleration profiles to get something a bit more realistic wrt hauling distance. Here is the result. Pa...

Re: Evaluating the Haul
Thanks Daniel,
This is just preliminary since I've only used a single stage acceleration, and had to guess some of the angles and acceleration rates so you can see that haul distance is excessive but here is what I get for the period from 0.6 seconds to 0.9 seconds in that cast.

Re: Evaluating the Haul
Thanks Daniel.
Just to make sure I’m reading that correctly the rotation rate of the rod goes from 0 to 16 radians/sec (roughly 150 rpm) in just over .2 seconds?

Re: Evaluating the Haul
Adding 1 more. This is the same as the previous run with the addition of constant upward translation motion of 1 m/s. This time peak speed is reached after 0.5 seconds (rod has rotated 45 degrees).

Re: Evaluating the Haul
You are welcome George. Here is another one with a similar set up. The difference this time is that the rotation of the rod is a uniform acceleration from 180 degrees to 0 degrees over the course of 1 second. Line hand movement is a constant speed of 1 m/s downward with no rod hand translation. Peak...

Re: Evaluating the Haul
Repeating the same run but adding translational movement to the rod hand moving it straight up (opposite direction of the line hand) at 1 m/s during the run gives the following results. This time peak hauling speed occurs at 0.21 seconds (rod has rotated 38 degrees) but does not become negative late...

Re: Evaluating the Haul
Playing around with the model again. In this run the rod begins horizontally with distance from stripper guide to elbow (the center of rotation for the rod arm for this run) 0.6 m. The line hand start position is together with the rod hand. The rod rotates about the elbow at a constant rotation spee...

Fly casting paradox (number 1)
If fly lines can fly then why can’t we cast unlimited distances?
Especially if we remove the leader that prevents the line from accelerating to sonic speeds and creating near infinite lift?

Re: glass vs graphite
I’ve misplaced my tinfoil hat so help me understand. Only expert casters (the ones who can tell you how many twists there are in your clinch knot after a single test cast of your rod) truly understand what the difference is in the feel of two totally different rods because only expert casters with s...
