Eye Splice solution for Fixed Amsteel Bridge

Jtaylor said:
This seems like less of a "knot" which we're supposed to avoid with amsteel than the OP's version. With a long enough bury, I wouldn't think the stitch is necessary either. The buried tag end is easily seen in amsteel and a mark can be placed indicating the location if anyone is worried about slippage. Seeing the OP's style of bury makes me wonder why a soft shackle "button" is an acceptable practice and why this OP's may not be. I like the idea of a locked fixed loop without stitching.

The stitching is to keep the tail buried with low, or no load, even flexing the splice at this point could cause part of it to pop out, especially the slick dyneema. The stitches don‘t help with break strength much.
I highest I seen for a dyneema knot that didn’t slip was 50% of the cords break strength. The rate of pull also has a lot to do with when the rope will break, the faster the pull the sooner the break because of the friction generated heat.

Non-Scientific test results follow.....:rolleyes:

I made a rope with a proper Brummel lock eye splice on one end, and a knotted Brummel on the other.

Then connected the eyes to my and my neighbor's truck hitches.

Then slowly drove off. It tightened up and the whole rope held enough for me to spin the wheels in 4wd on dry asphalt in 90° temperature. My truck bucked a bit then the rope snapped and I shot forward ten feet. That took me by surprise.o_O

So the Dyneema rope broke at the knot. This is not surprising. Any knot will compromise a rope's strength. I have no way of quantifying the load other than to say the rope was pulled friggin tight. View attachment 31958

Strong enough for a human drop? Probably. Maybe the next test is to tie a length and drop 200lbs of something 5' off a tree branch. Let the rope with the knotted Brummel take the load and see....
