He said that it worked for him "out of the box", and I had the 5/8" bollard installed on his. Of course each bone comes with three bollards included, so the Bone can be fine tuned.
-
He says elsewhere that it is Tachyon, which he preferred over the Imori he tried out. I do not yet have much feedback with this new Bone, but the 11.7mm ropes seem to work well.
-
Here is a video made of my latest Bone batch. It shows well how the Bone tends from the brass ring point. Thank to John for allowing me to share this. video.[ame] [/ame]

Max I like 14 oz. better : ) Luke, some climbers use the hole in the spine for tending. This seems to require a more leaned back position while ascending. Some love the D-ring on the top arm, which seems to work best with a more upright position while ascending, others attach a loop of throw line that runs down through the inside of the top arms and fastens to the hole in the spine. Try each and choose what works best for you. : )
-
Not sure about the grams, but it weighs 14 oz. on a kitchen scale. The New Bone is essentially the very same weight as the older ones.
-
Thanks, Luke. Here is a picture of the new Bones. Notice both the top and bottom arms are stubbier and the upper pivot is reduced 1/8", also the scallops on the arms are a bit wider to ease installation of the rope into the arms.
-
Just a note. I now have Bulldog Bone parts back in hand. This batch uses aluminum alloy 7075 throughout.
-
I am currently out of stock with the Bulldog Bones, but a new batch of Bones is in the works!
-
Thanks Rich. I did a quick search and at least one climber says "Cougar works well with the 3/4 bollard". If you like the loose VT tho, maybe you should stick with the 5/8" bollard, as long as the Bone does not creep for you with that size bollard.
-
I should add also that several climbers have found that the Bone tends best on ascent with a loop of throw line tied to the upper arm of the Bone, fastened between the upper pivot link and the friction link
-
Rich, It sounds to me like you may need to go with the larger bollard for the Cougar Blue, and I think that is what the US climbers are saying also that use that rope. The mid size steel bollard that I typically ship it out with installed is indeed 5/8" dia. You will likely find that with Tachyon the 5/8" bollard is best. Tyler climbs with escalator I believe, which is likely a more static rope with a denser? construction than the Cougar, which seems to suit the Bone best. I have not heard anyone say that the Bone "beds in" with use, although the rope tends to flatten with use. It should work smoothly from the outset with the right bollard matched to the rope and climbers weight. Maybe try squeezing the top release arm down, with the heel of your hand on the bottom arm, you can get very fine control this way.

None to NZ.....yet. I have to AU.

The Rock Exotica Nano swivel works like it was made for the Bulldog Bone, by all accounts. It is simple to replace the teardrop attach point on the BDB, by removing the SS cotter and SS half link pin, and replacing it with the Nano swivel by inserting the pin and cotter through the small eye of the Nano. A swivel directly on the Bridge works just fine also with the BDB. An OAR user put a LJ swivel on his OAR, however I believe that the hole in the LJ swivel is approx. 1/4", whereas the half link pin on the BDB is 5/16"
-
That was fast John. I guess customs now knows what a "Bulldog Bone ascender/descender" is in the UK. There is some good discussion at Treebuzz about the best way to advance the Bone while ascending. One way is to fasten a bit of throw line to the top release arms, between the top double joint link and the friction link of the top arm, and tether there to a chest attachment (see Sash style chest harness also at Treebuzz)

Adam, your private messages mailbox is full, so I cannot respond there. Look at my profile to find my email, and we can correspond there. Thanks Gordon
-
Paul, based on the reviews I am receiving, I am getting close to done.
-
I make each one from water cut parts by hand, and I do have a batch ready to go. I require a signed disclaimer with each. message me for details please, Thanks Gordon
-
Thanks Adam. The videos are all from users of the Bulldog Bone, thanks to Mike, Eric and Tyler for letting me share them.
-
bringing this video of SRT ascent and descent with HAAS into this thread. Thanks to Tyler for making the video. https://www.youtube.com/watch?v=Mmx1nGfhs7o

I have the Fiskars splitting maul and love it, well balanced and a nice long handle that allows a decent swing. The handle is warrantied for life, and it has been very tough and durable. I have three other mauls, including an all steel monster maul.
-
Here are two bones in action, both on one swivel on the bridge, connected to two seperatly anchored lines.
-
-
Since the Bulldog Bone is a different device than the OAR I thought I would start a new thread with some videos of the Bone in use.
-
I have two Bones ready, if interested, private message me. Thanks, Gordon
