Brummell Eye Splice, How much does it weaken the line?
Mon, 08/09/2010 - 12:26
Recently, I made a new pair of bridle lines out of 7/64ths inch Dyneema. The rated strength is 720 kgs. I used a Brummell splice to create the eye ends for the lines. How much of a loss in strength does this type of splice result in?
The product I used in braided Samson Amsteel ($0.27 / ft at West Marine).

Also, I used the center barrel from a gell pen as a fid. Pretty quick and cheap solution to working with small lines.

Funny, just found your post
Funny, just found your post after long research how to splice my own lines. Replacement lines and pig tales from manufacturers are sometimes hard to get and costly. Bought some lines and found this page very helpful.

Easy enough once you get going. Just made myself a Cabrinha center line that would cost me otherwise $39. Next will be some lines for my RRD kite. Glad I found out how to do it.
From what I read, the splice retains most of the strength when done this way. 80% I think. Knots would weaken the line a lot more. I've been thinking about the knots, can't be such a big deal if the line is big/strong enough. Most kites have pig tails on pulleys and bridal that have knots and it works just fine. I am sure one could get away with knots in certain places and could do without the splice. If I need a loop and have space to do a splice, I'll do the brummel spice, it I need short pig tails, regular figure eight knots should do.
Another great resource for knots:

This is the line I use for
This is the line I use for pig tails and most bridal and bar modifications.
SAMSON ROPE
AmSteel-Blue Dyneema SK-75 Single Braid
7/64ths inch for pig tails and bar leader lines and some brand like Cabrinha center line.
1/4" AmSteel-Blue for thicker depower line on my LF bar. Best bars as well.
