yeah, it's very confusing indeed, i know how you feel.Originally Posted by uninjured
simply put, as far as i read in various places, people tested and confirm that the brummel lock itself will fail at about 60% line strength. call it 50% to be safe, and consider that the strength of you dogbone if the bury is too short (which is basically the truth btw, as the bury will slide and all the load will be taken by the brummel in such situations). if you're ok with that strength, then ok, but i advise at the very least least 5/1 safety factor for hammock suspension, ideally 10/1. do inspect the brummels regularly if you use them, you will see the signs of them taking up the load if that happened (ask me how i know...)
for whatever it is worth, i would concur that 4in is way too short a burry for 7/64 amsteel, so consider the strength of those dogbones the strength of the brummel. it's not about failure, but rather about being clear what strength you can rely on (there's a big difference between 95% line strength and 50% line strength, regardless if you weigh anywhere near any of the two percentages). "know your strength" (eh? not bad)
on a side note, as i have pointed out in another thread recently: if you want compact, don't make a short bury, consider using a knot which is tested and reliable in dyneema (like the water bowline in this case), you'll get about the same strength, but more compact profile, and a loud warning right in front of your eyes saying "this is a knot, not full strength dyneema", whereas a short burry will trick most people, and even us who made them sometimes.
