Compact Bulldog Bone

I thought I'd come up with a good solution for the bridue swivel bdb connection with this setup
View attachment 28844


I haven't tried it yet but now I'm not sure because attaching a lanyard or another line to one of the other attachment points pulls against the rotation of the bdb.

Also, you can see the shackle I've been using to advance the bone. It works well. The only disadvantage is that it interferes withe rope installation and removal and must be taken off to do so.

I'm not so sure about that setup because I actually pondered that tool in my head. I imagined a Bone in each side hole of the Rook, leaving the center hole empty, but the orientation of the Bones would be 90 degrees out, and if you went slack on one side, the Rook swivel would get a weird side load. My impression is that it needs to be loaded inline with the swivel axis, so uneven dynamic forces to the side holes in a DSRT system would be no bueno. Not totally sure, big that's what went through my brain and kept me off the idea. I like a single swivel with a big eye, enough to hold both Bones. It loads the swivel the best.

And what the hell is wrong with pink, I am not giving those Komen thugs a dime, I just don't give a shit what color tape I use.

Nothing's wrong with Pink. You and Tom D will get along famously. LOL! Seriously, nothing's wrong with pink.
 
A nice clean solution for that rare occasion when u use DdRT. Still have yet to test it out. The arms move like normal. Thoughts anyone?

I'm gonna keep thinking of a different configuration for that cause it's a hassle getting the cordage in and out of that opening.
 
Yeah I tried that and it didn't seem to work as smooth for me. I will try it again tomorrow.

Cool just wanted to make sure you caught it. The bdb has come a long way in the 26 pages of this thread but not much of that talk has been DdRT. Would be good to add that option to the kit.

Curious, since less friction would be on the device DdRt would you use a smaller bollard for the same line?

I like how the DMM small swivel has kinda squat holes which makes for more difficult side loading on a single biner. But all the one listed I believe will accept two biners per hole.

Tyler how about just clipping the standing end of your doubled line back into your bridge?

To make the bone self tending I have put it at arms length with a prussic tied about a hands breadth above the bone with the end of the prussic loop around the entire top arm only (between the spine and the working side of the rope), and just snug enough to tend the Bone.

Will, no that changes the dynamics of the Bone, and while it will advance, it will not then release.
(at least not with my weight)
