first time seeing a double alpine butterfly. Looks good and strong like a Figure 8. I've been using two trucker's hitches in a row, but that sure works!
Neglecting the friction as well as the terrible angles one could argue this gives you a 5:1. Though I for one would rather go and try to make use of the secondary lines, treating them like a second pulley system. If the lenght of the first line allows for it.
I made a another slip loop on the end to tension the hitch. And made a second truckers hitch to make 9-1. If you add a 3rd truckers hitch to the end of the second. Its a 27-1. takes a lot of rope to move just a little. 27 feet of rope pulled to move a foot at that point. but cool to show a friend 27 inch's of rope being pulled to move the other end just one inch.
Here's an easy variation to increase the force without having to tie a Double Alpine Butterfly Knot. Just use the same eye TWICE! Make sure you put the running end through the eye the same way you did the first time so the parallel parts are not pulling in opposite directions and binding on each other. The beauty of it is, you can decide to add force as you feel necessary without starting over from scratch with the double alpine knot.
FINALLY someone that KNOWS HOW to tie a proper truckers hitch!!! I am AMAZED how many YT knotters do it wrong and spread their mistakes across the inter webs.
Because your anchors are not in line and hence your rope diverges you may not even have a 2:1 advantage. Put a scale on the standing end and you will find your true advantage.
This does not give a true 4-to-1 mechanical advantage. It only spreads out the forces over 4 lines on the one side of the knot. Could be useful to share the load on two small anchor points. Also, your water Bowline needs more tail. Otherwise, well done video as always.
The only reason it doesn't give a true 4:1 mechanical advantage is because of losses due to friction. Other than that, if the loops and anchors were replaced with pulleys, it would a true 4:1.
👍could you add a round turn on the last loop of the double alpine hitch to do what ive seen described as an “automatic truckers hitch”🤔 ..great video btw 👍
@@txtoolcrib The beauty of a truckers hitch is that it can be used ANYWHERE a knot needs to be tied under tension. Not just in a pickup truck bed. Places where ratchet straps aren't readily available. I use it extensively in camping, sailing and construction. Situations where a "ratchet strap" would NOT be readily available. Can you imagine how many ratchet straps it would take to secure a full load of antique furniture in a five ton truck? Are you going to carry dozens of ratchet straps for something like that? I don't think so.
Plus it's way easier to manage any length of rope than a long strap which tangles like crazy. And I've had those ratchets jam and be really difficult to release just in the moment I needed them to let go. I just like the rope better. Surely ratchet straps have their place. To each their own.
@@AquaTech225 Thank you for the reply. Yes, there are many ways to gain mechanical advantage but just as a Bowline is a specific knot so is the Trucker's Hitch. While I'm nit picking, 2 times 2x mechanical advantage is not 4x advantage.
@@vincegiese6734 I disagree. For the application demonstrated, there is NO better knot. Period. And, btw, the mechanical advantage in a trucker's hitch is 3:1, not "2x".
I don’t see how this is a 4:1 advantage. After threading the rope through, and pulling, the rope does not move through your first anchor point and the first loop of your alpine butterfly. This is easily seen as your rope has the decorative spiral, and looking at that, the rope doesn’t tension at all - it only pulls on the left side. For a true 4:1 advantage, reference the unreasonably tight truckers hitch video by first class amateur.

That soothing sweet sound of ropes tightening 😖😖 gives me chills. Like a strike when a bowling ball hits the pins 🎳

I use the same but do a bowline on the bight instead ! Great video!!
Like that double .. Saving that.
I believe this actually gives a 5-1 advantage vs the 3-1 of the classic hitch.
It will be lower in reality because of friction
@@KayakingVince very true. Friction will steal much advantage.
The classic hitch is a 2:1
This system is indeed 5:1 with no friction
Thank you great video very helpful
Absolutely.
That's awesome. Of course, I can never remember how to tie these knots when I need them!
Truth
Did amazing
Using "Ashley's Book of Knots" is a nice touch.
I made a another slip loop on the end to tension the hitch. And made a second truckers hitch to make 9-1. If you add a 3rd truckers hitch to the end of the second. Its a 27-1. takes a lot of rope to move just a little. 27 feet of rope pulled to move a foot at that point. but cool to show a friend 27 inch's of rope being pulled to move the other end just one inch.

Plus if he did run it thru the same loop instead of the 2nd one it would have been self-locking to boot (ie progress capture!)!
You can also tie two identical slipknots next to each other, which is easier to untie than the butterfly loops

Could help add tension bywhipping towards anchors with excess rope
Truckers hitch is a function of multiple knots working together. seems like you blew right threw em all. seems bad ass tho. 👍🏻
Because your anchors are not in line and hence your rope diverges you may not even have a 2:1 advantage. Put a scale on the standing end and you will find your true advantage.
I hadn’t considered that, but I tend to agree with you.
Don't you wanna tie the second loop in the working end, after passing it through the loop of the standing end?
Nice method for decreasing load, but too much friction. Try complex pulleys
This does not give a true 4-to-1 mechanical advantage. It only spreads out the forces over 4 lines on the one side of the knot. Could be useful to share the load on two small anchor points. Also, your water Bowline needs more tail. Otherwise, well done video as always.

You can, but it really only works well with smaller cordage, like paracord.
I believe it is 5:1 advantage. The first going through butterfly makes 3:1 and then second butterfly makes it 5:1. Count it again.
Very handy. It's a shame that ratchet straps, as handy as they are, are making these rope and knot skills a lost art.
Agreed, though I use ratchet straps most of the time.

Legal !
Not sure I understand what you are saying.
👏👏👏👍
I don't believe the double Alpine butterfly is necessary, you can get away with only using one loop and it will auto lock by itself this way.
Not the right knot
Make a video an prove it. There’s many ways.

Good point
Well I can see that 3 out of 4 ropes didn’t move a millimetre (because of friction) which means this is exactly 1 to 1 unfortunately 🫤
