Re: Torque Twist

It’s a form of forced unload. And how does that help? A forced unload means that your (rotation) deceleration rate is large, larger than the one a rod would take on its own (self deceleration). The consequence is a larger inertial effect which increases tip speed. It is likely due to a tempo driven...

Re: Heavier guides and effect on rod action

Hi Bart Action is an umbrella term which can include rod deflection, rod speed, MOI, and maybe other things which are unfortunately not independent from each other. The question here is related to the speed of the tackle. This speed is proportional to the (square root of both) rod stiffness on one s...

Re: Counterflex, energy loss and absorbation

Hi Gordy I am sending you a paper explaining the principle of calculation and another one with an example (a cane rod). It is necessary to take the rotation into account otherwise you have mo butt = 0 and mo mid = 0. This is what makes the experimental measurement of mo butt and mo mid extremely dif...

Re: Counterflex, energy loss and absorbation

Gordy We are not on the same page, let’s go back to basics : MOI = (mo butt + mo mid + mo tip) L^2 mo butt is linked to the self deceleration mechanism of the butt mo mid is linked to the mass transfer phenomenon (inertial effect) mo tip is linked to the loaded frequency curve The following graphic ...

Re: Counterflex, energy loss and absorbation

Hi Gordy Good question. We can measure the sum of equivalent masses (MOI) and the tip one (mo) just as you show with the frequency curves. Unfortunately I failed to find a measurement process to get an extra equation in between equivalent masses and solve the issue. The current mean I use is a calcu...

Re: Counterflex, energy loss and absorbation

Hi Tobias Without a line, the CF mirrors the energy you put into your motion. I can imagine that both options (1 and 2) can exist. All our motions (reflexes apart maybe) are damped, we are built with damping functions to produce fluid motions. I guess we can damp the counterflex from RSP to MCF and ...

Re: Counterflex, energy loss and absorbation

Hi Tobias First point: in the butt or more likely in the mid of the rod. That’s small anyway, unless the timing is poor. If the timing is perfect there is only energy left in the tip of the rod. The important loss is the energy remaining in the tip. That one has to be canceled. All energy is produce...

Re: Late haul - early release

Minimum Chord Length (between tip and butt end).
Something close to maximum rod load :D

Re: Single hand rods fly line standard

Hi Gordy

I do not know precisely, I think the tests are rather extensive. Among the tests there is a 30' load check if I remember well, but there are likely others.

Re: Has anyone built there own Sage rod?

Paul

You already promised to make the measurement with a rod which was supposed to have its guides changed.
