The OFFICIAL Windlass tourniquet ROS, Sticks, or platform attachment method.

I tried this today using Bullman Pioneer steps and 1” tubular webbing with a carriage bolt torque bar. Well, it works, but it got nowhere near as tight as my ratchet strap. The steps definitely had some give until I stood on all of them and it sort of helped set them, but in so doing they definitely where spongy, as evidenced by all the vet wrap torn clean off the back of the steps. The vet wrap on the steps I used all last season on a ratchet still looks great, so it’s definitely moving… Has anyone else done this with webbing and gotten it super tight?
 
The only thing I can think of that might be causing this is I’m using a poacher’s/scaffold knot to tie the webbing onto the slider collar. When I’m torquing down with the rod, or applying even more force by stepping onto the steps, I suppose it’s possible that the knot is incrementally getting tighter on the collar, thus allowing slightly more slack in the main line until the steps shift down the to a slightly wider diameter of the trunk. But, it seems unlikely because really, how hard can webbing squeeze on the metal collar until it’s immovably jammed?

Yes, it can and should get immovably tight.....no offense, I just want to help, but it's likely something to do with how you wrap the free end around the torque bar. Also you have to make slight adjustments in how much slack you start with before you twist the torque rod. To little slack won't let you get a full rotation which will allow the line to slip and not be as tight.
 
Also, the whole design of the sliding collar is so that you can have 180° of adjustability to reach that extreme tight spot rather than 360°. If you find that the tightest point is somewhere in between the two parallel points, untwist and allow just a tiny bit of slack, then twist again and see if the bar reaches parallel so you can lock it.
 
I'll take some pictures of what I have determined to be the best strap wrap around configuration.....
Can you post a couple pictures of your attempt so I can help diagnose better?

You definitely need at least one full rotation to keep the webbing from being able to slip. With just a little practice, once you find the sweet spot you'll see it can match a ratchet strap because it is the same concept just a different direction....and lighter and quieter.

Proof of concept worked. So simple.

i'm considering this also with amsteel and either pioneer or treehopper steps (5 of them for a ring)

does not having the width of the webbing make these squirrelly or prone to shift on you? or does the tightness of the amsteel take care of that?

i already climb with amsteel and steps, but it isn't the same type of pressure as a ring
 
This is by far the best orientation I've found. And I'm using the thickest strap you can get, the 6k lbs one that comes from treehopper. A regular ratchet strap is much easier to tighten. The pic with the rod parallel is when its at full torque, and I hope you'll be able to get it as tight as I can. I am using a carbon fiber rod cut from a 3/8" thick aircraft spar.20220625_192638.jpg20220625_192617.jpg20220625_192602.jpg20220625_192538.jpg

With amsteel, they get crazy tight, but I think they may move in a pendulum fashion due to the point of contact being a single point not wide, but if they're really tight they won't shift side to side.

what might help is do the same process but with a daisy chain for double thickness....but then why not just go with a strap once you start stacking amsteel to replicate a strap?

i know that daisy chains seem to spread out on the tree bark (with use on sticks) and seems to grab a bit better on the bark
 
I did not get a chance to take photos since it was about to thunderstorm when I had opportunity to practice. Figured sitting under a tree holding metal objects probably isn’t the brightest idea in the presence of lightning.

I’ll try to explain. Basically I pulled the loose end of the strap tight, then set my torque bar on top so the webbing passed under it and to the left, then I made a series of x-passes around the sliding collar, somewhat similar to your pictures @Samcirrus. I was able to get it notably tighter, but to get it tight enough to my liking I had to really crank on the torque bar, and the carriage head bolt kinda bruised my palm. Couldn’t imagine doing this in the dark and cold.

I tried my ratchet strap again. To be fair, although it was tighter than the tourniquet method, it now wasn’t leaps and bounds better as before.
 
Made an all carbon fiber tourniquet rod with cf tubing sleeve....works great. Orings make it silent.

Why is the word “windlass” not being used but tourniquet is?

So its the windlass rod tourniquet method. Better?
Also I never claimed it as original. I learned it from Thailand where they use it to construct massive scaffolding. They called it tourniquet.....
 
Ya guys, the thing is called a windlass. Like no joke. Anyway, that Windlass Method looks good
