    Well, that last great tip about making an entirely second anchor for the second 3 to 1 that is 30 feet away is totally brilliant. Never heard that one before. Great idea.

    Great video. As a blacksmith, I love showing these videos around my circle so guys can better understand how easily we can move heavy equipment in the shop. Too many have forgotten that ropes and pulleys even exist. Costly to set up, sure, but worth it in the end if you only need to move a power hammer or lathe.

    Dope. I just went backpacking and used a 3:1 paracord setup to pull dead branches off trees for firewood. Need to get a 9:1 setup now. 😅😅

    Good that you explained how to get both travelling pulleys to reset at the same time. Never seen that mentioned before.

    Great Video! I have a question though.. what would the ratio be & what would happen if you made the 2nd redirection attached to a rope grab off the back of the progress capture pulley instead of the rigging plate?

    • @dangerstall
      @dangerstall  Рік тому +1

      If I understand you correctly, I think it might make it a complex 11:1 . You would have to reset the pulleys so many times though.

      @@dangerstall Thanks Ryan! Yeah I used it today, not ideal but only had 4 pulleys in gear bag. Luckily I only reset once.
      Thanks again, really cool channel. Looking forward to more videos

    nice videos on pulleys! Are the Prusik ropes strong enough for all the load?

    • @dangerstall
      @dangerstall  5 років тому +1

      Yes, because they are only taking a percentage of the total load in a mechanical advantage setup, and a prusik will slip if overloaded. They tend to slip at about 1200 lbs of force for a 3 wrap prusik hitch. Give or take depending on materials and diameters etc...

    • @JS-zb1vv
      @JS-zb1vv Рік тому

      Depends on the load and force applied at the anchors gotta remember the force is applied in more than one direction

    lots of rope lots of pulleys not so simple but one man can​ do some enormously heavy pulling or lifting
    provided the skill sets are correct
    skill is everything. were proper technic is important to that's a biggy thank you for the knowledge
    the good stuff is always harder to find

      @@dangerstall easier to just simply show it, or describe why it isn't a 6:1. It's a 9:1 @k9solutions because he added another pulley at anchor vs creating a dead load using another figure 8. therefore that 3 traveled through pulley to create 9:1. had it been a dead load, it would not have traveled and would be a 6:1. good eye, but missed that one thing

    i only see a 6-1. shouldnt you add both 3-1 together instead of multiply?

    • @dangerstall
      @dangerstall  Рік тому

      When you put a 3:1 onto a 3:1 it multiplies and becomes a 9:1.

      @dangerstall  5 місяців тому

      Is that a question or a criticism? As you can see there is a red prusik next to the first COD pulley. Unfortunately I never got around to attaching it in this video. It would go on the prusik minding side of the first COD pulley.
