Vince,

Peak load around 12.2 N for 40 m/s line speed and 9 feet rod. Not that far from your estimate. You need a tough running line with that beast.

Still lots to ponder and try here, I'm very appreciative of all the input!

I'm meeting a good friend soon who is a top instrument mech, he has been researching equipment for these measurements to be taken and stated it should be straight forward to get good results, given the options available...

I'm going to try your experiment James, tomorrow when I'm not at work...

Regards

Hey Lee

Just read this on the Beeb web site:

"The shimmering green surface of the Margaritaria nobilis seed (common name - the barstool hogberry) has inspired scientists to design a fibre which changes colour as it is stretched. As tension is applied to the thread it changes from red to green and then yellow. The colour is determined by the thickness of the nano-structures.

This has great potential for use in micro-surgery. A surgeon operating remote equipment would know exactly how much tension to apply to surgical thread by observing the colour change."

This is moving on Will, they are now using it for bandages too

Maybe one day they will be able to make spools of it long enough to be used for line cores or running line 8)

If you want a fibre to go from yellow to green, or blue, we can say, ‘This is how we have to lay out the fibre to give us this kind of [colour] trajectory,’” Kolle says. “This is powerful because you might want to have something that reflects red to show a dangerously high strain, or green for ‘okay.’ We have that capacity.”

It would be kin useful for fly tying for the ham fisted.

:D

There would be no more arguing in this forum if they could make a full line / shooting heads out of it

Flycasting, so simple that instructors need to make it complicated since 1685

Got a Q++ at casting school, wearing shorts ;)

It wouldnt bother me if the best it could be was either a 000# or a 15#, it would just be cool if we could see tension variances in the system when casting 8)
