great there is a guy with some brain ..... I had that problem in my head and could not sleep ..... tonight I will sleep good ..... I have saved this video link, next time this issue comes up I will run that video again

its very hard to to see how you butterfly coiled that rope. the out and back, out and back was quick. And with the video quality, it makes it nearly impossible to see how you did that. I've only ever seen butterfly down with ropes behind the neck and down on each side. Your method looked more compact, but unfortnately I could not replicate it

It just so happens that I'm at 30.71 degrees so this was perfect. lol

What an absolute pro. Well done Mate! Easy on the ears, lovely work environment, love hearing the flag pole clanking in the background. He understands the psychology of a learner. Total witchcraft. You inspired me! Thank you! : )

Thanks for sharing

Wow. Thank you for sharing. I have never tied this knot so quickly before.

Thanks! Great stuff

Could anybody pls explain to me why he substracts 90-45? What is a point and purpose?

Amazing video, this one is a gem, so well explained!

Nice video series. I wish I had found this sooner. I have a project where I'm working on a tall ladder and needed to learn about ropes, knots, harnesses, etc. It took several days watching hours of videos to piece together all the info that you've gathered here in one place.

Part V

Please demonstrate that butterfly slowly. People need to see that. Searching for butterfly coil returns a method used by climbers that is quite different.

As a German, I find the hand gestures disturbing. Thanks for the info!

I use this knot every workweek. This is a great way to tie it. THANKS!

это лучший способ запомнить как вязать это узел! прямо то, что я искал. все остальные легко забываются или их попросту сложно вязать в пьяном виде на холодном ветру. теперь я даже в бы ину пьяный легко щавяжу такой узел! руспект, чувак!

Wow, I like it! There are many videos showing the wrap around your hand three times for making the Alpine Butterfly knot. Some show taking the middle wrap, top wrap, or taking the bottom wrap, then pulling it through the others; which one is correct. Very much I like yours best, easy-peasy lemon-squeezy.

Very appreciate the teacher trying to explain, still at his calculation, i would switch to Summer solistice sun set altitude angle instead of Winter solistice because summer is the time day is longest then we have more kW of peak-sun-hours. Starting point of calculation : top-right-hand-corner of solar array faces South (if Northern Hemisphere).

Excellent explanation and information, thank you!

What is the brand name of the rope grab? What size rope will it fit on? Do you recommend it? How much is it?

Great video one of the best I've scene in years very easy to follow great explanation.

Thank you very much! Making science simple!

Appreciate you making the video it worked. Exactly what I needed !!!

Thank you

Tiny panels?

That's pretty slick. Thanks for sharing it.

Quick correction at 5:40 or so: The statement was " one turn to the right and one turn to the left". In fact , both turns went in the SAME direction. If you do the two turns in opposite directions, the resulting knot sort of looks like a butterfly, but it's not as secure and could work loose.

Thanks for sharing this excellent method. Super easy both to learn and to teach! First watched this a few months back and have been showing and sharing to anybody who is interested ever since ... and even a few who weren't interested at all! 😪 😅

nice, thanks!

Thank you King!! Excellent explanation, graphics, pacing, everything. Thanks so much.

@4:57 I reach for my girlie Leatherman to cut the rope. This dude says "You call that a knife? THIS is a knife!!"

Don't miss this one folks! Jump to @2:28 if you're in a hurry - beaut, simple, effective technique that will work every time! Thanks for posting. Peace.

DON'T EVER DELETE THIS VIDEO! Since 2011 I still show this masterpiece to my own students to explain Resistance, Motors, Generators!

Thanks for sharing.

Is this being offered in 2023? I cannot find it anywhere.

It is tie, dress, set. Not tie, set and hope it was dressed

More people should watch these types of videos.

Excellent technique. Great outcome.

I’m still impressed by the outcome of that!

I love the way you explain things in your videos 😊 I am a 64 years young woman 😊 and I nearly fell off my roof whilst removing the hip high (I am 5’ 6” high), snow on my roof last winter. So, needless to say that this year, I bought the full body safety Harness and 6 foot internal Shock absorbing Safety Lanyard with double snap hooks on it to go on my back. I would like to know what type of rope do I need, because, I weigh 215 lbs and I’ll be up on a roof that is about 25 feet high x 30 feet deep x 60 feet large and with these dimensions on one side it will be tethered to my Pick-up on one side and to a big maple tree on the other side … what would be the best length? Thanks for taking the time to read this . Nicole

Thank you.

Thanks a lot for sharing this nice little trick! I've seen the general method that's used here a lot - even on Wikipedia, just without this neat usage of the thumb and index finger to keep the "loop on a loop" in place more easily. It's absolutely genius! One little thing I've noticed at 05:37 is that you're saying "one turn to the right [...] one turn to the left". You're twisting the rope in the same direction both times, therefore it results in a proper alpine butterfly. However, if you follow the verbal instructions and twist it in two different directions, it will result in a "false butterfly", which at the first glance looks pretty similar, but has very inferior properties.

Great solar orientation vid without an aide of an app.. I NEED a clarification though. The 'fudging' solution is - randomly pick any time of day, at AZIMUTH 0 and using the location's relative solar elevation on the chosen time, and using the location's latitude. Given these parameters in the Trig calculation I will get the same answer? Any help?

Great way to make analpine butterfly.i ve been using the 3 wraps on one hand method. This is a great alternative

Because of the coming micronova, declination is moving much farther, and much faster and so declination information is likely incorrect My up-to-date declination is 30 degrees, 15 degrees off from the official declination for my area. but there is still a way to recalibrate magnetic declination using the shadow of sticks recording the path of the sun---rotation of the earth has not yet changed. First stick will show East. Mark it with a sharp stick pushed in. After a few minutes you can mark sun shadow travel where the shadow has moved - Push another stick in to mark West. Lay a straight stick from the E mark to the W mark. Geographic north or True North is 90 degrees from the E-W line. With your compass pointing toward True North, note how far off your compass is now. That is your true up-to-date declination. More on micronova in my 2nd book, Surviving the Micronova: This Train Is on the Tracks is available now.
