Compact Bulldog Bone

Things to look out for. replace the bollard if it has 70-80 thousands of wear. Do not allow the top arm to become entangled by a dangling biner on the tending loop, stopping the free movement of its upward motion. Keep your weight on the teardrop, and do not let your weight to be borne by the tending loop or tending hole in spine.
 
performance tip. Adjust the bollard until there is little or no gap between the top friction pin and the rope installed.
You can squeeze the top release arm by bracing the heel of you hand on the bottom arm, but this is an individual preference.
It is very easy to install a Rock Exotica Nano swivel in place of the teardrop attach point, if you want to do it yourself as a retrofit. remove the SS cotter that holds the SS pin through the teardrop, remove the teardrop and install the small end of the Nano in its place with the SS pin and new SS cotter that comes with each new Bone.

Played around a little today, with the bollard all the way out, still seems to be a little stiff running on broken in Cougar. Left my foot ascender at work apparently, so I was only going up 6-8ft and coming down. Will play with it more tomorrow.

Nothing that wasn't already mentioned here in this thread as far as tending, what point to replace the bollard, which way to turn the screw and what what does to the bollard. It's all stuff I've read, but for me personally, i retain the information better if shown vs reading. I think I'm up to 45 pages of this thread from back to front, but a lot doesn't make much sense until you have it in hand.

As far as choosing one over the other, there are runners already being used at work. Not by me, but there to try. I can always order one. No one had a CBDB to try, Gordon is local, it's hand made, simplistic, and profits go to him and his coverage of materials.

While I'm not a "shop local" guru, and appreciate what Mr Bingham has brought to the table as well, I still have to go through a retailer. That's more of an excuse rather than valid reason. A lot of it probably has to do with "I want one of the two and I want it now". Gordon is about 1hr and 15min from my house with no traffic, and about 35min from my work.

Make no mistake about it, I like the rope runner while I've played with it. Ill own one too. Just the order I purchased things in.

My bad JustinK, I misread your post. I took it as you had seen the BDB but decided to go with the Runner instead. I see now you meant you would get a Runner also at some point.

Thanks Gordon, it is tempting to lean back while still attached to the tending loop, letting it hold me in a sorta upright position....does this qualify as taking weight off the teardrop enough to be deemed "things to look out for"?
 
I would say that using the tending loop to help hold you in an upright position is Ok as long as the majority of your weigh remains on the teardrop attach point.
 
Well today I used the adjustable bone on a decent sized tree. Started out with 6mo old blue Cougar and it hated it. I know my release technique is terrible still but it was jumpy. To the point where I used two hands to control the release better, but wasn't conducive to limb walking at all. It was tight even adjusted as loose as can be.

The good news is, I switched to a new Cougar Puke, and it loved it. I had to tighten up the bollard a fair amount, and still got my sliding stop so to speak.

Still can't figure out the best way to grip it. New rope was definitely a help. Just hope it does stay that way.

There was a lot of conversation on cougar way back. We determined that the puke worked for everyone and the blue somehow is different than the puke.

I think I read through that but wasn't sure if it was just the differences in old rope vs new. I think I need a new orange one too lol then I'll have all three.

I like to almost grip the rope above the Bulldog Bone pinching it while my thumb can trigger the end of the arm and my other three fingers can aid with control on the backside of the rope/top arm...
I have a short clip at the end of this video at about 7:11 -

Thanks John. I'll look through that. Got the perfect week to run it through its paces.
 
Smoothing up now. Used it to ascend 75ft then switched to the wrench just to work, and then down to 45-50ft for the final cut, switch back for descent and let it rip just to put some wear on it.

Second tree took the rest of the afternoon. Used it the whole time, but in all fairness, it was a live oak and I could pretty much walk the entire tree freely.

Both climbs were on the older cougar blue. Seems it just needed to be worn some before it would run on it.

I hesitate to say this with Worhaug present but...... It is likely a combination of the Bone breaking in, or more likely the rope being flattened and smoothed by use with the Bone.
 
Great pictures! does the tending loop work well girthed like that? I see that you installed your Nano swivel also.
 
Gordon, I ran it between the top arm and the back bone. It worked OK but I need to fiddle with it some more. Lot of drag on the ascent and I need to figure out where.

I added the swivel the night I came and got the bone from you. It's an absolute must IMO.

I ran my third bone without nanomod the other day it was nostalgically good. The drag could be mitigated with minor tweak in bridge length or height of tether connection. My swing dude Chester puts it just right for me.

So, I replaced the stock teardrop attachment point with the DMM Focus swivel.
It fits well, however there was some play in the "eye" of the green attachment point around the pin in the lower arm/attachment pin. I remedied this with a small section of latex rubber tubing - I placed it inside the green swivel eye, and passed the pin through - which was a struggle to keep all the pieces aligned and completely pass the pin through. I eventually got it through, and the swivel feels very, very snug on the pin, but still has enough freedom to pivot without too much resistance.

I've order the small bow shackle to replace the large bow shackle on the swivel. There is too much room for the carabiner to rotate inside the shackle, risking disorientation and/or improper loading of the gate etc. Keeping some latex tubing on the bow shackle and on the carabiner has helped keep the biner properly aligned in the mean time.

There's the details on that mod.
I had this swivel laying around so I decided to find a purpose for it.
Boom snap clap. Boner town.
