Since it appears Coronavirus has made me a regular uploader I guess I should provide a description.
My ropework started recreationally, having been climbing, caving and canyoning since 2001. After becoming involved with the volunteer emergency services this made me gravitate towards vertical rescue, where I became an accredited operator in 2004 and a trainer & assessor in 2005.
Over the years I've been involved with several intra- and inter-agency working groups to improve how we work; developed training material to establish new ways of working; and delivered workshops, courses and assessments across the state.
These videos are intended to provide training/currency opportunities during the Coronavirus epidemic, both for myself and for anyone who finds this useful.
Having a professional rescue focus means these videos will differ a little from might be seen recreationally, but I strongly believe the principles and foundations are common whether in industrial or recreational contexts.

2 Minutes on Rope - Blitz Anchor
The Blitz anchor is a technique for using a rope to create an anchor around an anchor point.
Its main advantage over other techniques is that it allows things to be attached at any point around the circumference of the anchor point.
Its main disadvantage is that it makes use of a knot that is no longer in common use - the double sheet bend, otherwise known as double becket bend. So you might need to learn a new knot to create a blitz anchor.

2 Minutes on Rope - Clove Hitch Anchor
มุมมอง 3304 ปีที่แล้ว
This video describes a process to create a two-point (load sharing) anchor from the rope that will be placed under tension. This is very common in recreational scenarios, particularly multi-pitch rock climbing, but the technique can also be valuable in some rescue scenarios so there is some value in understanding the principals behind it for vertical rescue operators and technicians
2 Minutes on Rope - Bowline
มุมมอง 1094 ปีที่แล้ว
The bowline, with its tail secured appropriately, can be an excellent attachment knot. For example, it is often used to attach a stretcher and stretcher attendant to a hauling and lowering system; or in place of a figure 8 as a primary anchor attachment. The main advantage a bowline has over a figure 8, particularly as an anchor attachment, is that after being heavily and repeatedly loaded a fi...

Looking for knots... Only seeing but hole
Nice! ThankYou!!
Unfortunately I couldn’t actually see what you were doing in this demonstration. I found it to be too far away from the camera and your hands were in front of the figure of 8. Picture in Picture should just have been the main picture because if you want a close up it should show as much detail as possible. Maybe a few good slow close ups of what your doing with more contrast “or a darker coloured rope” rather than doing it in 1 take.
Thanks for your feedback - I haven't watched this for a few years, watching it with fresh eyes I can see what you mean. Although I can't see a way to get full picture and no hands without 3 cams to capture. A sketch of the knot, however, progressing along with the vid, would be able to show the little details I've tried to communicate with words - which side of the standing end, etc. I'll see if I can put together something worthy of a re-upload - thanks again
@@chrisbennetts-cash599 If your going to use terms like standing end, bite, loop, working end etc you’ll only be explaining to people who already know how to do the knot. You only need one camera. Several close ups with comments edited over the final. OBS studio is a good tool if you want to interact with your production. There are some OBS videos on TH-cam so you can get an idea. Good luck.
@jag4762 love the thoughtful and constructive feedback - thanks again. I'm not a massive fan of re-shooting old stuff, unless it's something that'll cause some outrage and get people thinking - do you have any suggestions/requests for new topics?? 😀 This stuff started life as an attempt to continue providing training material to vertical rescue operators in our state in the early stages of covid lockdowns - although as they progressed began including newbie topics like this, without adjusting the language to match. Good call and good to be mindful of 🙏
@@chrisbennetts-cash599 Quick videos, task videos. No introduction to your life history, no mention of anything else than the task. No relating to other similar items. This isn’t aimed at you this is aimed at all the other long winded explanations of what the weather is like on the day, where they bought the rope, what type of rope it is, how much it cost, where they have been climbing etc. If you want to learn how to tie a knot or anything else you want it to be in easy to follow steps with simple instructions that you can remember and repeat. I’ve seen lots of rope access and top climbing videos and the thing that is really annoying is having to listen to waffle. If it can be explained and demonstrated in 30 seconds that would be a winner as your able to replay that video over and over in order to understand it better. Doing this your video gets seen multiple times by the same person and liked and if that is the case TH-cam will suggest your video to other interested peoples. But the principal is to have a short video not a fast one. To the point. The demonstration should begin within 10 seconds. By all means introduce yourself and the demo but keep it short.
@jag4762 hey man, you seem to have gone to quite a significant amount of trouble to give me the feedback that you have given. I want to acknowledge and thank you for that. In their birth these videos were intended mostly for existing vertical rescue technicians and partially for "just" general land rescue techs, and your feedback provides an excellent context for their application in the recreational arena. I can't promise change in the near future - these videos were the first year of covid, the next two were me breaking down - but I'm VERY inspired by the sentiment of your comments. Thank you!
Thank you for the very clear and precise instruction. The T method is a fantastic tool. Understanding load in the system can't be easier.

Amazing channel! 💯 I think you deserve way more views! Have you checked SMZeus”dot”com!!? It will help your videos rank higher in the search results!
Load cells are typically not very accurate at low loads. Most accurate at design load. One way to deal with the unlevel branch would be to use a single rope connecting the bottom of the load cells and then clip the weight onto this rope with a carabiner. That will equalise the load in the rope and therefore equalise the load cells.
Both excellent points, thanks Matt. Using two independent attachments was deliberate, to demonstrate how poorly load is shared at angles approaching zero degrees - IMO 30 is ideal for load sharing; more rigorous tests show a 70/30 split is more typical below that.
Well done.
Perhaps the wrong pants to be wearing during this demonstration.
I can't see what you're doing and the audio is garbled...sorry
Sorry you couldn't live with the poor audio - I'm learning as I go but have now upgraded to a professional-quality microphone, which you can hear in yesterday's wrap 3 pull 2 video. I've had several similar comments about not being able to see the rigging, and have just filmed my first two-camera shot so I can switch seamlessly to and from a close-up view. Who knew video training would be so much more complicated than face to face!?
