Locked brummel for winch thimble

[Tom Dunlap]

I removed the steel cable from my winch and bought 5/16” dia Dyneema. Now it’s time to splice the thimble in. Locked brummel seems like the best choice

Before posting I looked in the Treebuzz archives, Google and You Tube.

There seems to be different ways to splice it. Some instructions are t illustrated or well written

What directions should I follow?

Is a locked brummel the best choice?

Locked brummel for security and Samson’s instructions for 12 strand class II, with a precise long gradual final taper.

I don’t see the pigtail that I associate with a locked brummel

Fid length changes with diameter I know I’ll have to get more info

I went with a regular eye splice on mine. It's a long bury but seems like less work than brummel-ing the nearly 200ft of tail

I like locked brummel because it is foolproof. Honestly won't take very long to pull 200'of tail through, then never have to worry again.

Dyneema is slippery stuff and needs a LONG straight burry. Extra rigid for the most abused section of line, no thanks

The instructions shown doesn’t have a locked brummel, only a straight bury. The fid length for 5/16” is 6 3/4”. As long as the stitching to prevent the bury from coming out is protected, a straight is strong as well.

I think that with a good smooth taper behind the brummel you can cut the bury down to 6-8 inches.

The short buries are beneficial for hitch cords and there are two to share the load, a climber’s body weight. Winching will see higher loads and really no reason not to do a longer one.

Eh, I personally don't like the hand of doubled over strand. What is the winch for/on @Tom Dunlap?

 

[Tom Dunlap]

I’m going to sleeve the end with tubular webbing to protect the rope when choking

9k winch for my 3k Tracker...just in case

Honestly I've done the recommended full bury. I think it was fine. Every amsteel line I've ever seen has just straight buries, two full fids I think it was

From some sailing forums most agree with the 3 fid lengths for a straight bury, and a locked brummel reduces the strength by ten percent, it is there for preventing the bury cycling out with constant flogging on a sailboat. A long gradual taper was also stressed, to the point that the last strand is tapered.
