    Oh yeah! Learned to splice just about anything, wire, single and double braid, 3 and 4 strand. It has been a while on the wire splicing; I might have to brush up on that myself before I advised anyone! And thanks for the welcome, Tim. I have mostly retired from this stuff now and just have a small machine shop and bronze foundry. But still love to climb and it is time to try it in trees now that I work less. I am updating my gear and bought one of Gordon's adjustable Bones and just got a SAKA from Richard. Might get in some time with them this weekend if our weather holds sunny. - Stew

    Looks like it’s been about a year and a half since the Adjustable BDB was released. Has anyone worn out the top bollard yet?
    Are anymore “updates” in the planning for the BDB?

    @Scottyrunner100; This might not relate completely to your question, but have you seen surveyor's photos of his new possible prototype for a mini-bone?

    @TimBr; Are you referring to the one shown on Page 214, and 199 (I think is the same one?)
    Yes Sir, I have emailed Gordon about it for possible use on the fat NFPA static rope we use at the Fire Dept.
    I really like that adjustable feature though.
    The BDB has came a long way since Page 1, I have the latest ABDB, just curious if Gordon has any further advancements in the works.

    I do continue to work on the Bone pictured on page 199, which I call the Stubby Bone. It uses the same top arms as the lower hook arms but with a shorter spine.
    The Bone on page 214 has been named the Bullfrog Bone by Mac, and I like that name. It is smaller as it uses 3/4 size links, and will have hook arms upper and lower also.
    I plan to post up pictures of these Bones once they are made.

    I really like the xstatic.. I may have found my perfect srtwp line.. will see as it wears in how it changes and performs . Out of the box it was amazing. Tends so smooth in bdb. Up and down held well smooth realease . Fun day dead wooding . Dsrt all day Yale scandere vs. Tuef xstatic. Both real good. Yale little more energy absorbing feel.

    Here is the mini Bone and stubby Bone I have been working on. You can see that the stubby is not that much larger than the mini. Because the stubby has a shorter pivot length than the compact Bulldog Bone, it allows a shorter spine also. But because of the shorter pivot it needs a fatter rope, and I had the Vortex in mind for this stubby Bone.

    Contact @surveyor he is the brilliant mastermind. Make sure to check out his lanyard adjuster too. He has quite a selection of awesome devices!

    Has anyone been on any of the newer ropes that have come out in the last year or so with the bdb? Any feedback? I’m happy with tachyon performance but would like something more durable

    -any of the notch ropes?
    -Xstatic
    -Scandere
    -tangent/voyager
    -scion

    Andre, that Bone pictured is a very early Bone, with the all metal nubs, and the pivot length is 1.5 inches. You must have been using that for nearly 3 years now?
    I think you will really enjoy the new Bone with the hard rubber nubs and the pivot length of 1.375 inches, and of course the adjustable bollard with the monolithic arm.

    I've run the Adjustable BDB on Scion Blue. The performance was comparable to the Yale 11.7's (Arrowfrog, Blue Moon, PI/Tropical Ivy etc). The best performance I've found is with 32-48 strand "static" ropes like KMIII Max and Kernmaster.

    @Treetopflyer has used the BDB with both Scandere and Xtatic, he'd be able to tell ya about how those ropes fly with the Bone.
