Re: Double Haul increasing rod flex?

So, Mike's example fits well with either an early haul during back cast unrolling or a late haul during forward cast unrolling. Dirk, We agree on the direction of the bend produced by haul on the backcast. The haul velocity on the back cast is dominated by the rotation of the rod so its max velocit...

Re: Square snaps

I trace the lines in Archicad and print pdf from there using Foxit Reader PDF Printer. Dirk, I can imagine tracing all of those line shapes took a lot of tedious effort and admire your perseverance in producing such interesting overlays of two waves propagating on the same line . I was hoping that ...

Re: Square snaps

Why doesn't the mid-leg appreciably fall during such circumstances? This is indeed a very good question!! The first bend reminds me of those bead chain experiments where the chain is free falling under gravity and the chain lifts before it falls. Paul, I think it is the same rho_{l}*V_{tangential}^...

Re: Square snaps

Print a PDF, NOT set to "print as image", quite a large image size, then open the PDF in Photoshop and export as an image. Dirk, What program are you using load in your .mov (or some other video format) file and then printing that file as a non-image pdf file? I admire your perseverance in digitizi...

Re: Square snaps

I now compiled a fingerprint trace of "cast B" over the period presented on the chart. Dirk, Where is the video for that "B" cast? That will help me decipher your overlay plots. How are you making that overlay plot that shows the multiple line shapes so clearly? I'm thinking on a universal approach...

Re: Square snaps

Can you try and rephrase it using "fly leg bend" (the one on the left in all the images and footage) and "rod leg bend"? Dirk, Can you get an idea of what the line velocity around fly leg bend (the forward going bend) that you initiated with the first upward movement of the rod and how that compare...

Re: Square snaps

Dirk, Square indeed. Can you get an idea of what the line velocity around the bends for the forward going bend that you initiated with the first upward movement of the rod and how that compares with the line velocity going around the rearward bend that you produced with the snap after the first bend...

Re: Statements that make you go Hmmm? #1

In fact when people talk about stopless they are often using a very high rate of deceleration. Which is why I never bought in that term at all. Bernd, I agree with that statement as a true stopless cast (where no deceleration is applied to the rod ) will end up with the rod crashing into the ground...

Re: Leader designs

It’s 2000m above sea level. The difference in casting was remarkable
Paul,
As you know altitude has a big effect on density.
Image

At 2000 m the density is about 80% of the value at sea level.

Fog effect on density? Not so much.

Re: Leader designs

Fog on the other hand is more dense and is like casting into a wall for me Paul, If the density of heavy fog is about 0.05 g/m3 The liquid water density in fog is typically about 0.05 g/m3 for medium fog (visibility of the order of 300 m) and 0.5 g/m3 for thick fog (visibility of the order of 50 m)...
