[QUOTE=Riptide Charters;335754]Shoe, if it slipped it was tied incorrectly.QUOTE]
That definitely could be the case Terry- like I said, we didn't do 100 tests of each, just tied up a bunch and destroyed them I will say one thing, if that is the case and it breaks at 90%, it would be a great connection when you are re-tying in the middle of a hot bite because it's so fast.
In the original incarnation of the line tester I messed a lot with knots in 80# mono. The thing I learned was that complex "proper" knots could be 95% of line strength or 40% of line strength as I was inconsistent in my knots.
The simple knots - improved clinch, perfection, albright, spider hitch - all of which I can tie consistently all rated a solid 85-90% time after time.
The other observation and adaption is that when a knot slips its over and breaks at 50% or less every time. 1 drop of super glue on anything I really care about solves the slippage and adds security.
Thanks for the Vid Shoe !! I also like to destroy stuff. . I always wanted to make a tester and have a couple designed but didn't know what kind of a Scale to use. It's a very good thing knowing just what your gear and rigs will do.
Dude you took it to a new level. Can I borrow that. People want to steal we should put there hand in that and take there fingers off. All Tackle you should threaten that. They want to run from the cops Ok we will take off the legs first at the ankles and work right up to the hips.
shoe, great stuff. i work about 50% of my time in a physical testing lab and use instrons all the time. i have played around a bunch w/ some of hat stuff also. can't bring a camer a where i work so no pics sorry to say. only thing i see goingon w/ the test method you used(don't get me wrong i am not criticizing) is that your machine pulls at a steady rate. i have played around w/ different speeds on oour instrons and the faster you pull the quicker it will break i have found. i have been unable to duplicate the strike of a fish onour machines but i believe that is when the greatest starin is put on a lot of the stuff. keep it coming because it was great!!!
how bout a [pic of the complete machine in action too.

Agreed on the need for speed

My background was in plastics and we used instrons for all T&E workups and profiles. My fishing expierence would also suggest there is no possible way to set one up that duplicates the strike of even a 40 pound fish crushing a bait while the boat is moving say 7 knots and the fishy is moving say 40 kts in a different direction.
I have repeatedely stated to the charter customers it's one of most violent things they will expierence...that hit...zero to 100 in a nano second. Trying to calculate what the initial energy at impact alone is well out of my range. Drag start up on the reel, the release of the clip, if off a rigger or flatline..lots and lots of variables for certain. So the next best thing is to set a fixed set of parameters ala the ASTM T&E type and have a go at it. While it's definetly not perfect we can at least get an idea if what we start with is decent.
I think one part that is great to watch is the pull is in inches per second and not feet so when a crimp begins to slip or a knot slips you can see what is truley happening and hopefully film it
Ditto for hooks...soft materials act like something from gumby, while extremly hard ones begin to open then fracture at high values.
Lures and top water baits now this one fools us. Some plastic lipped ones are very strong testing out of 80 pounds before failure while others containing some metal to metal connections give it up at less value.
The one thing that using a machine with a steady rate of pull gives us is the ability to reproduce the test with some degree of precesion.
We have more brave volunteers to check out so stay tuned.
HI This is my first post here.I would like to thank vin for inviting me
to bring my line tester to the party I had a good time.And I would like thank
capt say for showing us how to rig a lure.I wish I could have stayed for the
rigging of the ballyhoo but i had to go.Shoe great video and the way you
got in to breaking stuff.met a lot of good guys.
First remember this is a home made tester.so take that in consideration.
OLDMUD the scale that I used is a spring scale I got it from mcmaster+car
I tried digital fish scales but there to slow to read out .
MATEY1 you are lucky to have accesses to a instron .To be able to record
loads at hi speed you would need to have a load cell and read out.I looked in to it but the cost was to much. so unless I can find one for cheap $ I am stuck with a spring scale
