  1. I like the natural metal, red swing arms with purple rollers would be cool. Come by my place and I will let you give these a try.
  2. Yes it should be wear resistant. The swing arms are aluminum, but the steel pins provide the bulk of the friction, and are very high grade steel wear points.
  3. Thought I would update the latest development on the OAR. Here is a picture of this slack tending OAR. Because the whole device pivots, it allows the OAR to tend slack in the normal. The short demo video was filmed by my youngest son. manner. [ame=http://www.youtube.com/watch?v=5TcgfUGZUeo]swiveling slack tending OAR - YouTube[/ame]
  4. Kevin won the recent Charlotte competition using the Singing Tree Rope Wrench with his custom solid tether. The link provides a video news report and they show the wrench and tether briefly at about the 30 second mark.

  5. I like how this hitch knot performs. It releases well and grips reliably. More wraps above for climbing with on narrower rope, but the form is the same below.
  6. The links come factory riveted on one side, and the spring clip side could be riveted also, but it would take a special tool....
  7. The hitchless pulley/rack would begin to release with pressure from above, much like a regular hitch. As long as there is a downward pressure on the top arm it would continue to slip.
  8. Ok Max, here are the pictures. The first shows the hitchless pulley/rack with the correct installation of the hitch climber pulley in relation to the headstock. Notice the blue inner side plates that will be removed along with the head, in order to switch it out to the hitch dependant headstock pieces, which are lying beside the P/R in the picture. The next picture shows the parts removed, and the hitch dependant headstock installed with the hitch cord tied. Notice how the legs of the hitch are on the opposite side of the rope as the headstock, and notice also the relation of the headstock to the pulley.
  9. thought I would post this video of the hitchless pulley rack, which better explains how to install and use the device. [ame=http://www.youtube.com/watch?v=8czYPRuL8t4]demonstration video of pulley/rack - YouTube[/ame]
  10. Here is a video of the hitchless pulley rack in action. [ame=http://www.youtube.com/watch?v=o0fiQvaQ6Pk]Hitchless pulley/rack - YouTube[/ame]
  11. Thanks to Nick and Mr. Hoffman. I am not sure how far the throw line will extend and still retract on reel.

  13. This all steel pulley/rack/hitch works well. the top rigid OAR arm added to the pulley rack makes a slight bend in the rope, which acts like a spring to engage the entire device. When weighted, the top arm swivels up and binds on the rope, sharing the friction with the rack below. It has little sit back, and tends slack nicely.

    Don't know, but I bet it will look a lot like this demo. [ame=http://www.youtube.com/watch?v=U6Oh_LXY4qk&feature=g-all-c]Long ascent- rig for the rope wrench - YouTube[/ame]
  16. Tony you may want to try this shorter configuration, Just remove the bottom link, and two connecting side plates, and move the 5/8" roller to where the 7/16" roller now resides, This will leave you with 2 5/8" rollers on the same side as the hitch climber pulley. It does not take as much friction this way below the hitch, as there is less roller chain length, but when releasing the hitch on a doubled rope it allows the hitch to bear a little more weigh rather than practically nothing at all. On a single line you have to work a little more to release the hitch but that is not nessecarily a bad thing. Gordon
  17. How hot does the spiderjack get on a longish decent? Does it ever get too hot to touch? just curious.
  18. I met Paul Cox this past weekend at the Charlotte competition and he had several of his prototype hitch hiker devices on display. What a great device! It is midline attachable below the hitch knot, and tends slack well, and quite compact (approx. 5 inches). He has used it on both a single and doubled line. There is a good discussion so far on the Tree House site with pictures and video.
  19. The sideplates are the original RW, the rest is modified. As shown it has to be threaded, however it can be easily made mid line by replacing the front link with a 5/16" bolt through the bottom sheave and the 5/16" quick release pin through the top sheave.
  20. I modified my RW today so that it has two attach points at the tether end. One for the tether and the other for over the shoulder or chest clip. The bronze rollers are both free to turn, but it still works fine to add friction above the hitch.

  22. Another option, if you have a surveyor friend with a metal locator, is to borrow the locator and scan the area to find it again.
  23. I use a 5/16" linch pin with a spring ring retainer as a standin, Less than a dollar at the local hardware.
  24. The only thing to do is make a device and see if it works. These two work well on rope for me and are quite compact
  25. Here is Tony's review of the pulley/rack. [ame=http://www.youtube.com/watch?v=CnSLvGuImNE]Pulley-Rack Review - YouTube[/ame]
