Awesome!

Is it worth the $$?

Hi Perry thank you for the video. Where did you get those pulleys from (link please) I never seen those in the UK. Cheers and thanks a million.

About the 8th video I’ve watched completely understood it with your one thank you 👍🏽👍🏽

I have a large dead tree laying between to hills and supported by a few smaller trees and its upper branches. I'd like to pull it over as it's very sketchy approaching with a chainsaw and down right dangerous. How would you approach this using snatch blocks or block and tackle? What kind of line should be used? The tree location will be hard to get any equipment in to do the pulling. What can be used to generate force? I believe using mechanical advantage is the way to go but I'm new to this and need some advice from a pro. Thank you.

I searched 'how to tie 2 pieces of rope together' and yours was the 3rd video. The Double Fishermans works for perfectly for my self defense weapon - a padlock on a string. Thanks!

Clear and to the point!

Option 3 (drop loop)is the best option since you have 6:1 mechanical advantage.

Good video. One thought; I feel like it would be better to put your “foot hold” ‘binder through the top hole in the ascender (so the rope is captured in the device by more than just the cam).

It would be easier to tie the prusick first and BFK last OR use a dbbl fisherman

This guy is the Bob Ross voice of knot tying…..aaaaand put a couple little loops here and then the rabbit comes out of the hole…..there and how bout a couple stop knots and just relax and slip this new little noose idea over your head……

I like that release system. We just use prusiks

This is the instructor everyone needs at their firehouse, very knowledgeable and knows how to deliver that knowledge to others. I know a lot of great guys that know how to do a lot of things but they don't understand how to communicate that to the newer guys, keep up the good work!

What brand / model is this tripod?

How you release tension of this first prussik after use?

Great video! Thanks! They didn't teach this in my Rope Technician class

This here I can understand.

Spot on for ny learning ability marra (listening to vid from other side of kitchen lol...

Thank you for sharing your rigging lesson.

Can you show the less cumbersome version please. The same knot but you've got the choice of it being an immovable loop or a 'choker'.... Both with individual uses. Also much easier to tie with larger and stiffer ropes.

Nice video with some excellent explanations and system example. I how ever would run both line to myself for working and safety (redundancy) as the patient is already in the basket they have two line they are attached too so if one rope was to fail the other would take hold.

3:1 is within the WLL of G rated gear even with 6 people pulling on it. (Or 2 with a 9:1) Assuming bomber anchors it still maintains a 10-1 safety factor. Testing with load cells is interesting because even after pulling all that tension on twin lines and adding a 180lb person load, the anchors still only saw about 2kn even at about 150 degrees. What’s more interesting, when we did a pickoff increasing the load to about 380lbs, the load cell only read about 2.4kn. The added weight had deviated the angle down. Static safety factors aside. Even a fall factor 2 from a 1kn load wouldn’t be enough to slip a single clutch or I’D let alone two. When done properly highlines are nothing to be afraid of and are a great tool. Love your videos btw.

I was drawn in by the title and hoping to see someone make a block and tackle. I am sorry to see that you didn't make anything, you just bought it and put it together.

You can always throw on two hand jammers instead of the slings 😊

The Bonus one reminds me of a reef knots i learned from my dad who was in special forces said he used this knot a lot =)

Very well done, however, this day and age, I can’t understand why we are still showing reliance on slow to build systems with the ability to have human error. Prusik knots and hand tied systems in many places, have been replaced by presewn and rigged systems. With a low angle litter harness, a harken winch and ropes with presewn loops, you can perform a low angle rescue with a fraction of the personnel and with zero need to tie a single knot.

This video saved my ass on a construction site - I needed to get all my tools, tile saw, tile etc from a patio deck up to a second floor patio deck - maximum weight was 100# - I had to get creative on the support arm that the pully was attached to - it had to swing in order for me get my products to clear the handrail - could not have done it without this video - thx so much for your excellent presentations 👍

I'm a little confused. The only change you made when converting from a 4 to 1 to a 5 to 1 was the location of the rope grab. Since you didn't change anything else, wouldn't you still be using the exact same amount of pulling force in both scenarios to move that 15 pound weight?

This is a good idea for tight places. Thanks

Maybe link the other videos in the description

Thanks! Just what I was looking for!

Could you rig this in a way where a chair is substituted for the log and a person could raise himself and then brake down on descent?

do you have a video on how a person could ascend and descend under self power using an ascension tool and braking tool?

I like this version.

Were you an iron worker ?

Great info thanks

Thank you good information to add to my arsenal of youtube climbing Videos im years out of the gym scene and just want back on the mountains so im brushing up on some technical stuff and just going for it once im comfortable... And this video has given my mind some ease when it comes to reppeling safely and how to incorporate the other devices. Thanks again

I used to just run the rope down to the tree next to it so there would be more of an angle not pulling the anchor straight up and wrap it 2 times and tie a bowline as close as to the tree as possible. That’s what you do when you don’t know any better anyway lol. I like method 1 and 3. I will have to start doing that

Something I've never understood, maybe you can answer. Let's say you're lifting a 1800lbs, using the 7:1 shown here. Do the blocks have to be rated for 1800lbs or less, since the advantage?

Thank you for posting, I’m starting to understand how this all works. I have no real application for all of this but it’s interesting to watch they see the mechanical advantage.

I don't see 7:1. How are you adding the Tensions?

Nice

Great tutorial thanks

Perry, wonderfully clear video! I do, however, have one suggestion. When you have your weight on the prussik(s)/ascender above the knot you are passing, and you take off the assisted breaking device, you are relying on just the ascender and prussik(s) to hold you. Friction hitches and mechanical devices like ascenders are not to be used alone to support your life without some type of fall arrestor device or system to back them up. The ascender could flip open, the prussik/friction hitch could come loose if pushed from the top or bottom, and then you could fall to your death. A simple solution in both of these circumstances is to tie a catastrophe knot a few inches below the knot you are passing (and below your bottom prussik when passing on an ascent), and clip this into your harness belay loop or hard points. An example would be a figure 8 on a bight or overhand on a bight or clove hitch. Then, if the ascendors or friction hitches fail when your ABD is out of the system and being moved over the knot you are passing, the furthest you can fall is to that catastrophe knot, and you will hang off it, saving your life. Overall, great video, but adding this addition would make it safer. Keep up the great videos, I think they are helping a lot of people!

Thank you sir

This is still one of the best demonstrations of the variations of the Alpine Butterfly knot on KZfaq. Excellent video.

What bag are you using to carry your gear and how do you set it up? Thanks for the videos

Z🇵🇬

Thanks for making this video! It really helped!

This is great, please could you do a 7:1? I can't find a video anywhere!
