    I'm sorry if this bores you to death but it is relevant to this thread. I made it as a guide for those wanting to set-up arborist single line work positioning or ascent systems.

    Hi Mark, long time no speak, how are you? Al North welcome to the forum. It's great to have input from other industries. I agree with Mark that a well set and anchored kern mantle/tooth ascender system has few flaws, and seeing that the climber is only able to ascend and then swap to a work positioning system there is very little chance of slack being introduced through the ascent climb. I don't agree that is is suitable for what an arborist has to do (up-down-in-out movement)but that is my opinion and I choose my system accordingly. Miss-use is easy to apply with any system and I wish that training bodies within arboriculture would address single and double leg ascent technicalities. Addressing remote high-point anchor setting is needed too. Mark, can you explain again about the strange pre-tensioning thing, why did he feel the need to do that?! I'm running an SRT workshop this weekend if anybody would like to come to Japan!

    Tachyon was not the worst - dont want a good rope getting a bad name, the db's were all as bad as each other. One went further because we dropped without a stopper knot.

    Hi Ben you weary traveller you ! I use a microcender. See the picture on my blog (thewoodenhand.tumblr.com). I dont mean to 'isolate' a branch mate. Simply trailing a second line after the first in the direction that you have thrown will keep your bomb point and negate the cluttery ones. Helps in not having the rope jam on the cluttery ones too. I know I know it seems like a pain but I rarely pick up just 1 throwcube (even if I end up not using 2). Dont knock it till you've tried it!
  6. softbankhawks
    There are two questions here. Anchoring and designing a rope system. Using a second throwline helps to secure a solid anchor point. Toothed ascenders and double braid are a sketchy combo, the sheath will rip and travel like a greased tube along the core for a great distance. Opened shell cams (croll, ascentree etc) need to work in tandem, they need to be backed-up but the same can not be said for an I'd, rig, Uni and hitch. What kind of rope do you use? I use a non-toothed cam in a rope-rocket which can be seen as a back-up although I'm happy with a sole hitch.

    'sporty' mode....just how I like it!

    Hi Joe, I leave more than a couple of strands. But if you imagine the core cut blunt at the tip of the eye...non in the neck...I dont forsee any movement...any weakness. The neck is relaxed onto the crossover. Old Snake achieves the best finish of the rod-neck db splices that I have seen. There is no more burying to do when the splice is set to work. A crushed neck plus heavy stitch and whip is counter-intuitive. I imagine that a db splice is more effective with no stitching too. It moves and 'works' under high loading. Of course the ppe aspect must be addressed though so it must be stitched.
  9. softbankhawks
    Hi Joe, Apart from treating each stage of the splice gently I think that not stitching the crossover helps and more importantly how much additional core is left in the neck. The crossover is massaged, milked and kept under tension at the final bury to keep smooth.
  10. softbankhawks
    All of the factory splices that I have seen have a rod-like neck. I began collecting splices (for a workshop) and noticed that the better ones had a supple neck, they could be bent over right up to the eye. The softness means that the fibres in the neck are not crushed and the balance between core/cover at the eye is perfect. Stitching is easier too. What d'yall think? Here is a picture from my blog: The Wooden Hand The top is a Yale factory splice, the bottom one has been done independently.

    Brion's method is clearer than most. Brion Toss Yacht Riggers, Sailboat Rigging::Search Results

    Hi Sloth, The piano wire fids make passing the rope through rope bit a lot easier. I use my samson fids only for measuring. Brion Toss has a formula using the diameter of rope and multiplying it by x, y and z. It's 6 of 1 half a dozen of the other, you want to achieve a smooth, secure and strong splice and which you can quite easily. Badger Mr Knott and take a db or 16 strand course...either one will teach you enough about tool and rope handling to achieve both splices. The class refers to fiber type...class2 is slippy high modulus fibres, class 1 is polyester. 99% of arb splices are class 1. Its a nice thing to do once youve got your head around it and it teaches you a bunch about rope.
  13. softbankhawks
    Grab some Armor Prus poly (polyester core) and splice with cl1 instructions. Be sure to make the neck as supple as you can for better e2e function.
  14. softbankhawks
    Im so happy that people are engaging with single line work positioning. I got dissed many times when I took my Uni to UK arb shows 5 odd years back, some people became very heated and mistrustful. The zk1 opened things up cause it was so cheap and it worked so well. From the zk1 ideas for rope wrench set-up have evolved, would you go back to using a floppy rope tether? SRWP tools have to achieve certified status. It should come with a non-flopping tether which would be designed for a specific pulley and be tested with a specific hitch and cord.
  15. softbankhawks
    Sorry for the derail....)
  16. softbankhawks
    Mason, the Wrench concept is not analogous to a slack minding pulley. In any way. For descent the Wrench is PPE. An ascent that un-intentionally turns to descent can be aided by a well tethered Wrench, ie the motion of the Wrench is akin to the carressing motion when setting a hitch - so is PPE. Just because the Wrench can become neutral doesn't mean that it is non-PPE. A heavily locked hitch (or even melted hitch) caused by a Wrench not engaging automatically could result in complicating a rescue scenario. It could and of course there are ways around a melted hitch but the fact must not be negated...it could.
  17. softbankhawks
    Are ISC working on something?
  18. softbankhawks
    So smooth out the hitch issue. People balk to easily with french style hitches. I blame that cursed Blakes hitch, its made babies out of us !! There are many people in the UK that can offer sound advice.
  19. softbankhawks
    Why not do it officially? I know it works(with my homemade specific designed tether), all wrench users know it works but it's the people that dont know that need convincing and testing it officially shows your duty of care AND the products viability. We cant all climb as well as you Kevin and shouldnt have to use tools that need creative interpretations to be useable. If no products for SRWP become bonafied it will halter other product developments. Id like to see a pulley saver/guide style top anchor that can offer several ways of changing a 2:1 to 1:1.
  20. softbankhawks
    Yes I agree but that isnt my point. The Wrench has enabled a larger discourse on SRWP. SRWP is becoming stuck in a rut and if a tool doesnt engage with existing EN and CE standards it will make the revolution dissipate. The Wrench could easily be tested to a number of different standards with compatible components. If you want to change parts as a matter of personal climbing style that is another matter. The Wrench has to grow up
  21. softbankhawks
    Im happy to hear that you are working on a bonafide tether for the wrench. Its only half complete without it. I think it needs a sprung connection to scoop the wrench into semi engaged mode and of course must not have a collapsing attachment - karabiner - so fixe' and hitch climber's must be catered for. Please keep focusing on this Kevin (and not new tools yet!!)

    Yur, the steelie feels way to easy to spin open....???......probably just imagining it?? I don't think much on it now anyway. We made a video for a Japanese supplier.....[ame=http://www.youtube.com/watch?v=l6F5A73EfQ0&sns=em]?????????? (Introduction of Hitch Hiker) - YouTube[/ame]

    The Unicender is rated to break at 7000lbs. An eye2eye way over 22kn. Those scaffold knots on the HH will cut through and break below 40kn. What was your point Ian? The HH body was built to last....and it will. Designed for treemen that dont have a gear addiction.
  24. softbankhawks
    I heard through Mike Popham that you bent the zk-1 and deformed your zk-2 prototype. Maybe the 40kn was designed to test you!! Go on....see if you can !!
  25. softbankhawks
    Do you think that our gear is OK at 8kn? What do you see as a satisfactory rating?
