Default Dyneema short splice

For reasons of my own, I needed a 12-strand Dyneema splice that is not the standard long bury, nor even the shorter tuck-bury proposed by NER and Samson. So I made an all-tuck splice, by following each strand of line in the standing part with one from the, er, other part (is there nomenclature for that?). Tedious, but tidy if done carefully, and six full tucks did not make an unreasonably long splice. Before I have it destruction tested, can anyone tell me if there's an obvious reason (other than that it takes 1000 times longer than a regular bury splice to do) that this is not commonly used? Seems elegant enough, and will meet my needs perfectly if it works.
Thanks,
Ben

No idea, but would be interested in seeing some pics and hearing what you find out from testing!

Default Similar splice is used for single braid nylon

My storm rode lines are made up from 1" nylon 12-strand single-braid, and the recommended splice is to
1. Split the end into two bundles of six each.
2. Pass one bundle of six through the standing part
3. Marry adjacent strand of opposite twist, to create three bundles on each side.
4. tuck each bundle back along the standing part, over one and under two.

If done on the spectra it would be painfully slow but would be shorter than the normal bury.
Could also do a lock splice to make the eye (A thru B, B thru A) and a very short bury, with stitching.

Default different materials

Thanks Craig,

I'm familiar with the 12-strand Nylon splice, but that nylon 12-strand is not the same construction as the 12-strand hollow braid, and the nylon fibers come with a twist not present in the dyneema. So I'm concerned that being a differently laid, non-stretchy fiber, dyneema might not be as amenable to that splice.
But, since there hasn't been a chorus of doom, I'll take that to mean there's no obvious, glaring downsides, and carry on with my experiments.
Thanks again.
Best,
Ben

Default Splice

Hi,
And first, I believe that it is the same construction in both nylon and Spectra; the big differences are helix angle, twist, and of course relative slickness.
As to splice options, Samson's method is a hybrid, meant to reduce splice length, without the tedium of an all-tuck splice. I recently made drogue eyes using a slight variation on a Yale splice. You can see the finished product on my Facebook page: https://www.facebook.com/photo.php?f...type=1&theater. More tucks, in a much different pattern than for the nylon splice.
Fair leads,
Brion Toss
