    Compact Bulldog Bone

    I can't see this working well since the bollard needs to be changed at some point. An epoxy would not be easy to release and heat release adhesives like red locktite, would probably release from the heat of a long fast descent.

    Regarding the BDB and HTP... No grooves cut in mine either. So I switched out to the 5/8" bollard to try on HTP and as I expected it had no more hold on 11mm HTP than the 3/4" bollard...as in none. It's not that I badly want to use the DBD/HTP combo as much as it bugs me that it works for...

    I don't understand at all. I gave it another try today with the 3/4" bollard on 11mm Sterling HTP. My experience is that the 3/4" will provide more hold for a given rope than the the 5/8" bollard. Same results for me. No hold at all. Not even what I would call a controlled descent. Switched...

    lol...the different experiences each of us has amazes me. I couldn't get the BDB to grab on new 11mm HTP at all.

    Robins

    Not long. Once it started to fly, I got to "fly" it about three times before it didn't return. I'm sure it had a VERY short life having no skills to fend for itself.

    Robins

    I usually have a flock strip the dogwoods in the fall and a holly hedge later in the winter. Many years back, I raised a robin. One day I fed it a few wild strawberries and several days later it picked all of the red M&Ms out of a package I let spill on the table....stupid bird.

    I was thinking about getting some Cougar blue, but maybe not.

    Brandon...platinum 10.5 or 11.5? The BDB works OK for me (~180 lb with gear) on the 11.5 with the 3/4" bollard but the 10.5 would be too thin of a rope.

    Best way to mount on Protos helmet.

    I can't resist any longer. Everytime I read the thread title, "Best way to mount on Protos helmet", I want to respond 'from behind!':bananas:

    Thanks for the vid and music selection biggun. After the vid, I couldn't get Peace Frogs cranked up fast enough. I had an up front seat at a Doors concert when I was 15.

    My method was to drill a small hole through both arms at once to insure alignment (only had to mark one piece) and then drill the larger pin diameter hole part way through both arms from the inside. This way the pin is captured when the arms are assembled.

    SAKA

    An experience of mine with a SAKA I made some time back would tend to back this up. I made it with the CT chest ascender oriented as on a HAAS and incorporated a few small "improvements". It worked beautifully until a few of my "improvement stitches" failed allowing the ascender to rotate...

    Thank you sir. By coincidence I slipped a tight fitting section of surgical tubing over the tether on one bone to keep a mini-biner oriented and it is stiff enough to keep it away from the lower arms. I have not done this to the other one yet and sure enough, the mini-biner can hook the lower...

    How to choose the best line?

    FWIW, using a Hitch Hiker on 11mm HTP, I have found blue bee line and a distel hitch to work well.

    As this spacing is reduced, the pressure required on the arms to release the bone is also reduced as well as resulting in less holding power on the rope. The closer spacing/less hold helps to accommodate larger diameter ropes.

    1 inch :eek: + 5/8" bollard would be a glide to ground on any of my ropes.:sisi:

    Out of curiosity, what is the spacing on the short holes?

    ML...I think your upper arms have the second set of holes for the pivot to let you experiment with what works best for your 'fat' rope and were a special item. The newest bones have a friction link to pivot distance of 1-3/8" while the previous standard was 1-1/2".

    A change in rope diameter and/or construction frequently means the upper friction bollard needs to be changed. Typically a larger diameter rope requires a smaller bollard, however this is not always the case due to rope construction. Construction can effect the bollard size on approximately...
