    It would doubtless go easier if you had one more hand.

    Does anyone know how to make one continuous loop out of a piece of rope using one of these constrictor methods?

    The locked brummels work very well in that application
    Yes, their my "helpers" whenever anything with a string comes out. They can also sew better than me too

    Hey Opie, thanks for the pics--thats exactly what I did to make my double side brummels. Yours are much neater looking though. I made some up with the 7/64 and it was much easier this time. Your right in that they made a fine spare rope to carry.

    When the whoopie was first introduced there was a lot of discussion about the locked brummel vs the straight bury with lock stitching in regards to derating the line. Was this cleared up and I missed it somewhere? I thought the locked brummel derated the line significantly ( close to half ) and this was the reason that Samson had the whoopie sling rated so low in line strength. Again I might have just missed it somewhere since innovations happen here so rapidly.

    The (UN)scientific testing I did had a whoopie of each variety break at nearly the same point.

    KNotty got a message from samson that stated that the actual results they were getting with the whoopie sling was a derate between 0 and 10%.

    From my original post on this. http://www.hammockforums.net/forum/s...ad.php?t=12319

    It doesn't totally agree with opie's testing but the bottom line is changing from locked brummel to standard buried eye splice doesn't change anything in a whoopie sling because it's not the normal point of failure.

    *********
    I wrote to Samson Ropes about Amsteel whoopie slings asking where they would fail. Here is their response.


    Using Amsteel Blue whoopie slings for suspending hammocks is a very interesting application. Thanks for the link to the thread on the hammock forum, it's a good discussion.

    Recently the reduction to 60% of average break strength for Amsteel Blue whoopie slings was suspected to be a low value. Testing showed that it is actually around 80% depending on the size of the rope. On every test done the break location was at the point of the adjustable whoopie tail exit.

    In collusion, the locking brummel has less impact on break strength reduction than the "sudden transition in size where the adjustable section exits the bury". If a traditional buried eye replaced the brummel, the same strength reduction would be expected because the adjustable bury exit is the weakest link.
