Yeah, afaik and from different sources the strength between a regular bury and brummel is almost the same.tomtom wrote: ↑Fri Sep 20, 2019 6:30 pmBrummel is virtually identical in strength than long bury - this is many times confirmed by lots of independent measurement. Long bury is very slightly stronger but both made splice which is stronger than line rated strength. There are two brummel type - normal /which require free line end/ and inverted which doesnt not. Normal look esthetically better - strenght is same. I use both types acording situation.
Foil, you look like handy man, please ignore all comments that its hard, complicated and it require 20 attempts. You must do 1 or 2 practice run and after that you are fine.
It is much easier than make perfect finish on wings and I actually enjoy messing with lines.

an actual test rig and results, i have chopped lines with scissors and simply tied overhand knots, no sleeving, to make a larks head - never had one snap.. would like to know exactly how much weaker this is though.. the truth!
That is true for making sets of lines. You can mark them all under the same load and cut and splice them to the same measurements. It is not true at all for making individual lines and not true if you make any errors during the marking or splicing process.Jfactor wrote: ↑Fri Sep 20, 2019 6:00 pmGetting brummels the same length is NOT hard. I've done countless sets with brummels, never without issues. The key to this is cutting all of the lines to the same length, and marking the line where you want the loop to fold. Once you do this, its easy to adjust the loop slightly right before you lock it. Since all of the lines were cut to the same length, the shrinking that occurs due to bury will all be identical.

I have set up a breaking strain rig in my garage, and I am able to test up to 300kg.longwhitecloud wrote: ↑Sat Sep 21, 2019 9:32 amid like to see actual breaking strains of different sleeves and even simply an overhand knot... in the same dyneema

Yeah I'm not sure why this happens but when it fails an inch away from the splice you know the splice is where it failed not the line. Just keep it mind if you have a line failure.OzBungy wrote: ↑Sat Sep 21, 2019 10:17 am
PS I have seen test videos of knots and splices being broken. The failure was always 25-50mm from the splice or break, never on the knot or splice where you would expect it to happen. It was suggested that a shock wave is passing through the line that causes the break.
