Closed ring device in Brummel splice

Yes I am using the Colligo Marine technique.

So for something like the baby stay, I would just make the other splice with the "other" technique. If you study the "Colligo" way, you can see how the locking tucks work. If you take the tail of the line (with extra for the bury) and pass it through the body of the line below where you want your eye to end. Then the second tuck is done with the *other* end tucking through the smaller section of line, just where it exits the first tuck.

If you just take the bury end and "S" it through the line, it won't be locked at all....

Hopefully this makes sense... it's simple but there are a number of subtleties to it that are really hard to convey. When in doubt, just buy the splicing book. I'm sure this won't be the only time you use it once you have it.

You can also use the Samson technique for splicing which uses a lock stitch instead of a Brummel. I tested a piece of Amsteel with eye splices on each end, one of each type. It failed in the middle of the line. In other words, both splices were stronger than the line they were made of. Samson claims their technique is just as good or better than a Brummel, I can't remember which they said, and I have no reason to doubt that.

Hello,
Re Brummels vs stitches, it is true that adequate stitching can be a strong as a locked Brummel, and I don't feel bad about using stitches in situations where Brummels are impracticable. But given the amount of stitching required for truly reassuring security, and given how easy it is to introduce deformation into the line with stitches, and given how long the process takes, I still prefer Brummels, which also happen to be profoundly secure. Plus, if you use the McDonald method, you will know how to do the multiple version, for times when you need a tool-less utility splice.
Fair leads,

fwiw,

I'm just replacing a bobstay that was something like 11 years old, done in Amsteel Blue or something very like, simple bury around a thimble. I undid the splice and found that the tail was quite long, nicely tapered, and there were two whippings done on it. (I didn't do the splice.) The bobstay is still in good shape - the reason for replacement has to do with the metal tang on the sprit having failed, so we're going to another style of bobstay.

The situation is a sprit on a modified F-27 trimaran, and it takes a fair amount of heat (1500-3000 lb), so I'd say a well-done simple bury works too.
