12 strand type 2 locking brummel

[countryboypa31]

I'm looking for directions on what the taper and bury length should be on a 12 strand hollow braid type 2 locking brummel.

Specifically for samson amsteel winch line.

Three full fids for a straight tuck. I would just do the same for a mobius or regular brumel then you are good to go.

Your are not going to save that much line and no need to split hairs, just go for strength on a winch line.

If you use the 3-fid bury as Samson specifies, you can save some useless effort by not putting in the locking Brummel. This assumes you stitch the throat as Samson specifies.

I am with you Moray. However sometimes I just like the lock for aesthetic reasons. Plus it's fun to do with a single end. Still amazes me every time.

Oh well simple minds simple entertainment!

yeah i just went straight bury. thanks, it was more out of curiousity (sp?) I thought i had read somewhere that with a locking brummel you could shorten the splice and taper somewhat. But i could be wrong. Thants why i asked. Thanks for the responces.

I am definitely ammused by the locking brummel single side procedure. So much fun!

Yep you can! In the locked brummel, the brummel is the splice. You could do a lock (or maybe a double lock on amsteel) and bury a fid length. Stitch down the tail either way.

Same here, that's the way that I splice Amsteel as well.

Thanks nick. Good to know

The longer bury on a standard straight splice can add longevity espically to an Amsteel winch line. Twice the cordage at the end to abraid through so to speak.

The longer bury also adds strength. The short bury with Brummel has unknown strength. What IS known is that it has a minimum strength no matter how short the bury*. This is a very nice feature for certain special applications, but I am afraid many people think that the locked Brummel even with a very short bury gives them a full-strength rope.

It is possible to measure the minimum strength guaranteed by the locked Brummel by simply making one with no bury and pulling it to failure. I have done this a number of times and, depending on the type of rope, measured ultimate strengths from 30 to 40 percent of nominal. Always use long buries if you depend on the rope delivering near-maximum strength.


*The bury has to be long enough to resist unraveling if the bury comes out and the Brummel takes the entire load.
