    Thanks Cody. Have you tried Paul Cox's hitch hiker device, when you saw Dave?

    Here is a better video of the hitchless pulley/rack, showing how to install and use it on the rope. http://www.youtube.com/watch?v=8czYPRuL8t4

    pulley/rack

    Thanks all. It does release very nicely. I measured the sit back from fully collapsed to fully weighted and the difference is 2-3/4"

    The pulley rack can be configured to be hitch dependent or all steel.

    Here is a video of the metal hitch/rack/pulley tending slack, ascending, and descending. The video was cut off but at the end I was demonstrating how to release the hitch with a thumb on the descent lever. http://www.youtube.com/watch?v=o0fiQvaQ6Pk

    About an inch or two while limb walking, 2-3/4 inches from fully collapsed to fully weighted.

    pulley/rack

    Ok here is the all steel pulley rack. The top rigid link is configured just like an arm from my OAR device. It tends slack very easily as there are rollers all along one side of the rack and OAR arm. The arm bends the rope ever so slightly when on line, so that when weighed it pivots upwards...

    pulley/rack

    Paul, I did try it either way and it does tend slack either way as the Tibloc swivels up when tending slack "backwards" or through the biner like regular. I think that this configuration though will not provide quite enough friction. Perhaps if the Tibloc portion was larger and placed on a...

    The Tibloc is not quite large enough, so this tends with too much friction, but this arrangement has potential. The OAR arm above the Tibloc is midline attachable, and when weighted, swings up and binds and so acts as a hitch above the Tibloc. When the OAR arm is pulled downwards the device...

    Looking forward to your product Paul. Maybe we could trade some gear!?? That is one of the nice features of your using a distel hitch, as there is less sitback. Gordon

    Probably so, I have not descended any long distance on it.

    pulley/rack

    Using a Tibloc (with the teeth ground off and smooth inside!) and adding a roller chain link for the hitch attachment, I made this tiny hitch hiker. The roller link pin forces the rope to take a small bend through the Tibloc, when weighted.

    Thanks, Yes Casey has another device called the Dogbone or Dogleg. I have loaned it to him for awhile. It is based on Kevin's RW concept. It sounds like it will be traveling to Cary for awhile also. here is a picture of the first and second models.

    Hello all, first post here. I am not a climber, my profession is a registered Land Surveyor here in NC, but I love making various climbing gear and have also made a device called a Bulldog OAR (see youtube). I had this pulley rack at the Charlotte competition, and Paul was kind enough to give...
