Compact Bulldog Bone

Received my Bone a few days ago and tried it yesterday for the first time with the 5/8" bollard. ......Went up and down Sterling 7/16" HTP several times....

...Then I went up and down Yale Poison Hi-vy 11.7 mm. It gripped better but I could still get it to slide by bouncing on it. When it did slide, it would stop after a few inches. I'm going to try both again with the 3/4" bollard, after I recover from my frostbite....

I'm about 185 with gear and have had no luck using new HTP with the BDB and 3/4" bollard (or the Rope Runner). Here's a link to my earlier post #573...http://www.treebuzz.com/forum/threads/compact-bulldog-bone.28246/page-29#post-404544

The only thing I have that works well with 11mm-7/16" HTP is the Hitch Hiker and it is a superb combination if you like that static of a rope.

The 3/4" bollard and Yale 11.7 Aztec work very well for me and is my go-to climbing system. Most have reported needing the larger bollard with the Yale 11.7's.
 
What we need is someone around 200 lbs. fully geared up that has good results with the Bone on the widest variety of lines. Then, we take that Bone and 3D print the living heck out of it! It does seem like the newer versions Gordon is making are working a bit better.
 
Too much bucket work for me lately but...if I remember correctly, I was using the 3/4 bollard with Cougar and Yale 11.7's. I think Worthaug uses the 5/8 though. Who knows, alzheimers may be setting in :)

Vet, just think of a crane removal in which you want to go back and forth from DdRT (on the crane) to SRT (on the spar). This device works in either configuration without any changes except for where the standing end is anchored (to you or to the tree).

I was just out in Ohio and watched my friend Justin destroy a few dead trees off a K-Boom. He rocked the Bone in perfect fashion. This tool is really showing its promise.

It actually works really well in DdRT, it just needs a slick, low cost component kit to make the change from SRT to DdRT seamless. I'm working on that... ;)...along with another 1,000,000 things.

why not srt off the crane and just leave the line on the ball tip when you change to the tree Eric? Anyway, when I like to change to ddrt I still love the zzag.

I guess that's possible, Dave...leaving a line on the boom, but in my opinion it seems like more rope to manage, and it may become out of reach if the line is deflected through brush when the ball is coming back to you.

Here's another example...dead tree, unsafe to climb, so you get lowered in, tie off your balancers, descend and make your cut, and bail out...all DdRT. Now you're on the ground and the crane is going to lift you back in, so you have to pass all that line through your device to shorten it up and get back on the ball. With the Bone, you can pop it off the line and reload it right near the eye splice termination. Might not be such a benefit if you're bagging your line over the sheave as you feed through the device, but still nice in that sense.

Besides the Hitch Hiker, this is the first device that goes seamlessly from one technique to another, and that's really saying something for handbuilt endeavor...nevermind the astonishing ease of on/off.

At the end of the day, many of the things we rave about may not mean all that much to the bottom line, but they can make a difference in our minds and perhaps add to the fun. It's a good thing we all have different devices to choose from and decide what we like. Free Climb, Tautline, Blakes, HC, Pinto, SJ, LJ, ZZ, RW, HH, RR, CBDB...where does it end/begin?!?!?!?:)

After having read for days about the bone and dreaming to receive it ASAP I'm wondering how many of you bone users had forgotten about any other device for SRT considering the bone the best they'd ever tried...??? From what I see and read things like hitch hiker, hitch climber or any other system with a hitch could be just a device of the past...is it just so???

As far and mechanicals and multi-scender goes, I haven't actually tried many others. I have had the privilege of trying out the Rope Runner, but not having a lot of experience with either the Bone or the Rope Runner I can't make any promises. What I think I have noticed about each though is that the Bone acts much more like a hitch while descending and the Rope Runner acts much more like a hitch climber while tending slack. It takes more time getting used to the Rope Runner's release, however, as it has more built into it (spring, pulley, more moving parts, etc) it moves along the rope smoothly and efficiently with more versatility across rope choice and such. The on/off of the Rope Runner is more involved and has potential for dropping pieces, whereas the Bone is simple and intact the entire time. They are BOTH incredibly cool tools with a lot of engineering and long hours of perfection. I can't say that one is better than the other, but, for me, the on/off of the Bone has a strong pull that I gravitate to. The Bone is slightly heavier than the Runner, but I personally like the feel and build of the CBB.

I love both of them. They each have their strengths and qualities that make for an excellent and efficient tool in their own ways. Just get a bigger gear bag and collect them all. :sisi:

Comparing mechanicals to hitch cord... I would have to say the mechanicals make for much more fluid movement. Dropping down to the next branch below and being able to control your descent with confidence is incredible. With a hitch I am never sure that the cord won't bind and leave me at mid point to slam against a branch or two. The consistent movement up and down the line is positively delightful with mechanicals. However, I will never say I won't touch a hitch cord again. I appreciate the art and skill behind pairing cord to rope and tying the various friction hitches to customize the performance. Enough for now...

Oceans, can you explain the Slick conversion to DdRT? Does it work for the new Bones?

I don't know if it will work super well at all, but it's clear in my head. It's a matter of sussing out all the lengths, etc. It sort of falls along the lines of a Spiderjack Dyneema. I would LOVE to see if the Bone can self tend like the SJ with the right kit.

This is my attempt to demonstrate the ability of this latest CBB. I know it's all been shown before and I am late to the game, but I wanted to make it clear that the Bone, or at least the latest version, works without a hitch...I mean, yeah without issue. I really like it on the Tachyon too. I tried it on Imori and it wasn't as smooth, but functioned well, all the same. Thank you Gordon! I don't think I will be able to stop praising Gordon for a job well done. Anyway, here is a video of me just quickly showing it off. Although I forgot to show the on/off which is one of its coolest abilities.

John, what's the length of the upper pivot on yours? Is it the slightly shorter one that could work with Vortex?

Mhhhh...clear and honest! Thanks John!

Thanks Eric, I was thinking about the position of the tending lanyard, yes, yet to play with it and the DdRT will for sure be positioning more than ascent. Lots to learn with the new tool.

Oh, cool. You were thinking of tending from your SRT system while in DdRT?

Gordon could answer that better than I can, but it is shorter than the previous version. Not sure if that means it is compatible with Vortex though...
