attempting a tute here

Cool! I'll give it a try. Thanks.

Thanks Tami, I appreciate being encouraged to do these things.

That was pretty easy! MUCH easier than pulling line through itself .


Thanks Tami~!

I use a bastardized brummel (aka tuck splice?) where I just pull the line through itself twice then bury it. I don't use them for "structural" stuff though I have made 12 trap lines with them and they have never slipped at all... and those are conditions wherein they would slip. of course I am lazy though....

The idea of these splices is not to reduce the strength in the line by adding a knot. I reckon that one of these,mid way along a line, may weaken the line significantly.

Anyone got any authority on this?

Mike - has the punisher eaten a brummel vs. a simple tuck splice?

Sometimes one end is already fixed or simply too long... here is an alternative way to get the same Brummell

I got NO Authority! but that is my understanding as well... HM line (dyneema, specta, vectran, etc) don't like knots and can reduce up to 70% of its breaking strength.

Oh yeah. Splices retain the most strength vs a knot. Bowlines cut themselves apart at about 60% of the ropes working load - sometimes less.

A brummel splice is our preferred 12-strand splice - however tapering the bury is critical to integrity of the splice. The line will typically break at the end point of the bury. If you think about it, the outer strands are taking the load, and the inner strands have less tension because of the transition. If you do not taper the bury, I've seen them fail at 50% of the working load because of the abrupt transition.

What is the difference between this brummel splice and a regular eye splice? Seems in both you pass each through the other and form an eye, then bury the tail? Are they the same just called different names?

No there is a difference... the regular eye splice the bitter end passes through the line a few times. The brummel is different... try Tami's example.. .it is much easier than the second link (its hard to pull the knots through the hole and then open them up again as in the second example) and will show the differece very well....

I think thats called a Single Braid Eye Splice Lock Stitch

A brummel actually forms a lock and regular eye splice usually weaves the tail back and forth through the same line. A regular eye splice can work itself loose if the line is repeatedly loaded and unloaded if it hasn't been whipped/lock stitched - which opens another can of worms...

Mike,

What I've been doing is a Brummel mid-line in my screacher and chute sheets and just luggage-tagging the made eyes through the tack grommets in lieu of adding shackles. I guess in this case you could say it's fabricating a Brummel with a super long tail and no bury.

I've had the chute up 20kt range, and the screacher in 15's and these splices haven't failed so far. And we're talking Fboat, not beachcat.

Maybe it's crazy, but it's working for me.

The fact that you are using a brummel is why it works.

I've been trying to do an eye splice like shown and having issues. When they say to "taper" the end, how the heck do you do that? Thats probably the biggest issue at the moment.

Mike: I'm rolling with the brummel, but to be honest, I can't see a helluva lot of difference between it and a knot. Comments?

Clayton: See if this helps:

At the end of these link is a good example (or 2) of how to taper that i recently found- http://www.precourt.ca/brummel_splice.pdf

here is another
http://www.samsonrope.com/site_files/12S_C1_EyeSpl.pdf

but is a regular easy buried splice weaker than a brummel? Or vice versa. I haven't ever had even a simple straight up (like on the samson page) eye splice come undone if the tail is long enough (which makes for a very long taper and smooth transition)
