Compact Bulldog Bone

Nothing better in the hands, yet yer pants better not interfere with the footie . My experience was it didn't fall through ct footascemder in there as smooth as some other choice lines. Still a great rope.

I opened my bone up the other day to try swapping the tie-in teardrop out for a petzl paw I had lying around but unfortunately the paw is a tiny bit too large to pivot around nicely in that spot. I was thinking it'd be really nice to have a second clip in there for doubled ropes. Has anybody else tried this, maybe one of the other brands of paws will fit in there?

Love to hear what solutions you may come up with for that.

I'd also really like to hear how Patrac from the Czech Republic got on with his BB that he built.

Never tried the RR yet. Besides maybe slightly better responsiveness, and maybe it being easier to bomb out the tree on - I have no desire to. For me BB - no separate parts, quicker, easier on/off the line wins every day. Too cold to take extra time, plus if you drop something in a foot or more of snow - good luck finding it. Spent a bit of time over at the tree house lately - gained a greater appreciation of all of the development and collaboration gone into this product. Always more to learn.

Well I've only an hour or so on a rope runner... It's an ingenious device for sure but I think the bone is a little smoother on descent, maybe more time on a rope runner would prove me wrong tho. I think it is dependant on a spring to get its grab started where the bone does this just by its geometry, the upper arm basically being a rope wrench. Don't forget the unicender too, also a great and very clever design
 
Thanks JefLong. Considered the Uni in the past - was put off by wear issues and release trickiness (installing a drum, having to put rope over top for smoother release). Very interested as to where all mechanical srt devices are going in the future. I feel we are now getting about 3 main devices that all feature a sort of smooth rope grab at the bottom and a wrench type thing at the top. Very similar in function.
 
I have not tried a paw at the connection point on the Bone, but have tried a split steel connector there (both swiveled). That arraingment did not work for a doubled rope.

I have in my possession a Bone which was used for 6 months (average 4-6 days use per week, as per the former owner). The steel friction pins, which are very high quality,
carbon steel had no visual discernible wear other than being polished, When I put a mike to it, it revealed 2 thousandths of wear on the friction pins. The spine has about 12 thousandths of wear. If you can extrapolate from this single data point, I would say the Bone should be refurbished after approximately 30 months.
 
I do love the prettiness of the Runner - and I'm sure its awesome to use.
I love the adjustable cams that the akimbo will have - its going to be easy to adjust to multiple ropes very quickly (but I dont have a lot of ropes or commercial time pressures when I climb), and otherwise looks like a bling-ed and pimped bone. And it has a fancy slick opening mechanism.

But the bone is made of off the shelf parts and a few bits of plate/extruded ally - cut buffed and holes drilled. Gordon will probably correct me - but I think the hardest part in manufacture is cutting the link plates to make the gates - very hard steel and you got to get it just right so that the gate can be pushed over the pin - just.

And that means the bone's parts can be replaced very quickly and very cheaply. Gordon speaks of refurbing a heavily used bone around the 2.5-3 yr mark - and really all that involved is a new chain link (shelf item, couple of quid/dollars/shekels and the gate can be reused) and maybe a new spine - easy enough to make yourself (assuming you're happy with the original style - straight ally extrusion with two holes drilled) or if you have the original spine, you can just turn it around for the next three years.

So whilst the design process and action is nothing but, the bone itself is so simple and so cheap to maintain.

And..... my baby bone arrived just before Christmas (Thanks Gordon). I've not climbed with it yet due to a bad knee, but I've played low - and its great! Soooo compact. I'll attach a couple of pictures - but the grip was great doubled (lanyard style) and I thought I'd try it single... with my weird South African rope whose name I can never remember (not Cougar sadly) it holds my weight no problem. No slip. And not I'm not featherweight...

Anyone who uses a lanyard every should have one or two of these. I love friction chord - but now I can use it just for inline attach points etc. Very nice.

Vortex has been a big no in the runner for me, with or without baby bump. Flattens to the point of uselessness. Kmiii is my go to hand saver with the runner

interesting, I found it worked pretty well. Did it slide on you? my biggest complaint was it seemed to grip a bit hard.
 
It slid bad. I only had one run where it didn't. That being said, I didn't fool with the bollard cuz I am lazy. The flattening was pretty intense though. And I like the kmiii enough that it didn't bother me. I like having a rope dedicated to each device. I also have a couple pounds on you

ill have to revisit. vortex is so fat, I feel I had more of a problem with it gripping too tight.

I would agree with that statement Kevin. That was actually why I made my first custom body for the runner. Now on Prism mostly and it has to be the most slippery rope I have ever climbed on. Releases great but man does it want to run when you back off the bird. Definitely need to roll the top for both go and stop.

It's an all around great line to climb with the bone .Tends well.. fairly consistent release ..its a different feel than a hitch.metal sliding down rope just feels a bit different tham cordage to me..works better after breaking in a bit.. The cougars really awesome as well. I've even got an elongated top bollard and new arms from Gordon that allow my arrowfrog to perform really well like these other two mentioned. Previously it would flatten and creep, with this new bollard its created the perfect amount of friction to stop slipping yet still Tends great.

Guess I don't know what the arrowfrog is. Cougar model? Thanks for the input, much appreciated.

Tachyon worked well for me for a while. The interface with the bone is great. I just don't like how bunch tachyon is. Some don't mind it. I did. I actually wasn't using my bone all that much for a while because I didn't have a rope to compliment it. I just got on vortex at the beginning of December and fell in love all over again. Big fan

Sounds like a few people like vortex, may have to get another rope it seems....thanks for the input.
