Knot Strength, part 1

Have you ever just thought about a Uni Knot.  If you look very careful, you'll note that the part that winds around the other lines will actually end up straight and that the loop part will actually wind around the the rest.  If you visualize it very well, you'll see that the knot ends up just being a snell knot with one tag end, the end that goes through the eye loop, just being doubled back on itself.

Here's the snell knot.



If you take the hook out of this pic and run the line that went through the eye of the hook through another hook facing the other way, and double it back through the middle ... well, that's an uni-knot.  Can you picture it?

When you tie an uni-to-uni knot you are just snelling one line around the other, and the other line around the first.  If you trace through this, you might imagine the the stress points of an uni-to-uni are entirely different than an uni-to-hook.

kallitype, how were the uni-to-hook knots breaking on you?  Just curious.  Also, can you test a snelled hooked.  Maybe just snell a hook mid-line and pull from both ends, which kind of tests the front hook of a 2 hook mootching rig.  Clip the hook at the bend so that if it goes flying it doesn't hook anything.

When doubling the line through the hook in the eye-crosser knot, I think the load is getting spread differently with the double distributing it more evenly on the loop and hook.  Hence the actual knot part become less critical as it is more or less just acting as a bumper stop with pressure on the actual knot.

have started prepping for the oregon rockfish /lingcod touney, and filled a reel with 30# stren microfuse braid last night.

think it was here, but cant find it, i'm looking for the knots to link flouro to braid so i can use a good abrasion resistant leader.

any help?

ya i wanna know that too...ive tried a few with not much success...but maybe i was tying them badly or soemthing

Just for an FYI, i use a large swivel a couple feet up from my jig. It keeps the line from getting twisted up, which is extremely annoying when the line gets wrapped around the tip every time you jig your pole. I just use an improved cinch knot and have for years with no major loses..

Here's the snell knot.

Isn't this knot the genesis of the "ass hat"?

Uh, oh...

Richard, I usually just use a uni/uni knot. If I lube it well when I cinch it down, I don't have issues with the braid cutting the mono. If you do, you can try doubling the braid over, before tying the knot and that might help. With the uni/uni I can add as much of a topshot of mono as I want.

Thanx... i'm going to use both yours and CBY's ideas, tie on a good barrel swivel to the braid then attach the flouro to the other end.. i'm thinking 5-8 foot leader ought to be plenty..

Kallitype's knot tying session and his posting results here got me thinking about butting dis similar lines like that.. if this were fly line i'd just do a nail knot and be done with it.. that ain't happening with braid and flouro...trust me it doesnt hold

guys, thanx again for all the wonderful help you provide so freely..

Don't use too long of a leader or you will have a hard time reaching the fish when the swivel hits the tip. 2-3 feet is fine.

thanx, roy.. btw, don't tell brian, but i got some stuff that looks like your ling toy too.. i just had to pull your leg about it...
