3:1 isn't 3:1, and so on. 

Some common questions: 1. The X-Lock shortening is covered here in my Clips & Cuts channel (please sub, trying to get it monetised) ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-pt93-89fZ9A.html 2. This is NOT a full review o the Offset Rings, it's efficiency only. To come; Thermal Analysis and then Offset Ring vs Symmetrical vs Block 3. Thank you again to the person who sent the rings, I don't have budget to buy everything and I don't like asking to be sent free stuff direct from companies. I know, right? How weird of me. 4. A Bearing Ring does exist, for example the RR30 which I've reviewed and tested here ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-bCMJvk9L1rE.html 5. For the original Efficiency video see this ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-rdlRRAbzCzA.html 6. Is it my practice to discuss with anyone who has an interest a draft video before publication. I've found any disagreements are better figured out before it goes live, it serves nobody's interest to be wrong; not mine, not yours, not the company's. Now when it comes to opinion...that's different. We didn't all agree, but at least we agreed to disagree. I don't deal in gotchas or sensation, plenty of others doing that. There are pros and cons of every product, and if you see anything that is all pro, or all con...then it's probably not unbiased.

Thank you to whoever sent the Yankum winch rings for this and future test

👍 for the Yankum donation. I want to know the real facts concerning these offset rings. Thank you all.

Very well tested and presented Robert, thank you Sir!

21:26 "If you need more than 3.4, you may need a professional recovery" Absolutely. At some point you begin working with forces that can do real harm to your vehicle if everything goes right and to everything if things start going wrong. Your summary in this video is spot on. I think using a 4-1 can be great for spreading out the forces on anchor points and reducing load on the winch, if you're using a 4-1 for "more power" you need to start being very careful.

I love that load tester! When I worked construction, we used a tester with a giant analog dial indicator. That Bluetooth function is a safety factor that is unmeasurably good.

You're on fire dude. Go go go ! Love the content!

Been looking forward to these. Thanks to whoever bought the offset rings. Excellent data.

Those rings aren’t cheap, but I’m glad they’re in the right hands!

Thanks so much!! I’m a little surprised to see the Yankum 5 to 1 is so low!

Great video! We recently picked up two Bluelink load cells for our classes.

Very well done. Interesting that Yankum and Factor 55, two of the most expensive rings out there, we’re the most inefficient. I actually guessed that those two rings would be the worst.

Thanks for this very informative test. It is really great to have some real data to show what is actually happening. What I especially appreciate is that you aren't just trying to declare something the "best." Any of these can be a useful tool and can help make the recovery safer and more effective. The key to your results is that it has helped us better manage expectations.

Awesome job, as always. Seeing a visual graph is a bit of a game changer.

quite interesting on the losses experienced, I guess the only major advantage ater the SB rigging is physical speed reduction, if at all that can be listed as an advantage.

Thank you Robert, another excellent video.

This was another amazingly informative video. And very timely. Thanks, Robert, and to view that, I sent them to you. #Respect I'm keen to see the Yakam specific review as I have been so close to purchasing, but not quite convinced.

Thanks for making this video! As always, your very pragmatic, objective testing clears up a lot of confusion. Looking forward to the next one!

Impressive. I've been waiting for this test. Thank you.

I'm sure you will put it straight. Will be good to see how the Yankum performs. I was wondering before and now when it comes to blocks , often they are left in the tool box untill needed, So what is the difference say Dry vs Greased pin/bearing ?

It’s been my experience that the only anchor point available is not directly in front of me, and requires a redirect pulley. That completes things.

Thank you Robert, fantastic and non biased information as always. I will be looking forward to your review of the Yankum Ropes offset rings. I have seen them in use in person and I have been impressed so far. Keep it up man!!

Data based information. Love it!!

This illustrates the beauty of winches... With the exception of the anchor point it's very hard to exceed the breaking strength of the gear. You take a cat S shackle at 4.5t and achieve 4:1 (so more complex that what you've already done which is already a lot of effort and gear) and you're still 5t inside the capacity of the shackle. The only thing in question is the strap around the tree. It takes very little effort to achieve the goal safely. Compare that to everyone's favourite kinetic recovery...

Nothing but data, the way I like it! Can't wait to see the Yankum video.

Another great test - thorough and consistent, long on facts and data. I'd been curious about the offset rings, so thanks to the donor who made the test possible. I think I'm sticking with my new Saber ring and my old snatch block - between the two it's hard to imagine not being able to rig appropriately (well, maybe an extra one for redirection?) If you ever get the chance, it'd be fun to see some capstan winching. A whole 'nother world of risks and tricks.

Thank you for doing this test. I think this is very good quality and rather unbiased data that is starting to paint a much better picture. I would love to see a part 2 that filled in some of the holes I see though. 1. Rig the Yankum ring and a large diameter ring as a Spanish Burton. This will show more of a comparison of losses in the 4:1 range being more about the Spanish Burton being more efficient because it just has less rope on pulleys. ( The parts for a Spanish Burton 'should' also be up sized which gets closed over a bit ). 2. I'd like to see a traditional 4:1 done with separate rings and pulleys to show that friction losses are going to happen with those systems IF you don't have or can't use the SB technique because of space or length limitations. I'd extrapolate you would be closer to the double ring rigging like Yankum vs the SB rigging numbers.

Always very interesting and informative 🤔🤩👍🏻

Nice work. Thanks for the effort

The last tests have me scratching my head. Between 3:1 and 4:1 there is a theoretical increase of 33% with an actual increase of 19% 4:1 to 5:1 there is a theoretical increase of 25% with an actual of 20% How does that work? Am I missing something? For a bonus point, it would be nice to know the load the 5th leg put on the anchor. Any guesses?

In a situation where a vehicle is very stuck, bogged to the rails in thick wet mud for example, would winch loads will exceed 100% of the vehicles weight?

Excellent info, thanks for doing this test.

Danke!

Love seeing your videos but I would have liked to have seen, the red winch FM - 24 or FM - 12 setup

Great video as usual. Can we get a video about winch gearing?

Thanks for another great and informative video, really find the practical results in comparison to the theory interesting. Have you considered switching things at all so that the anchor point becomes the stuck vehicle to be recovered ( no/non operational winch) being recovered by a winch equipped vehicle using a second vehicle or fixed anchor point beside the winch equipped vehicle to reduce the loads on the recovering vehicle while increasing the force available for extracting the stuck vehicle? Hope this makes sense. Interested as I use my winch as often to recover/move loads as I do for self recovery and could see advantages such as reducing the chances of dragging the recovering vehicle towards the stuck one.

Love your work!!! I’m a little surprised in how close the F55 and Yankum were in the 2:1 configuration given the earlier recovery ring testing. Was there there enough load so the F55 and Saber rings were rotating or just sliding through? (I may have missed that in the video)

great video. just found the channel and just subbed. PS. I hate Casey LaDelle HAHAHA

Robert, I dont' know if you have covered this but do you have an instructional video of the "X" device, the one with the two horns on either side over which one places ropes - I would like a simple working example (I have not been able to find an explanation).

What I think you missed is the difference in weight and the difference in size, compared to the mechanical advantage. So 2 rings vs 2 pulley blocks. How much lighter are the rings? Also can two rings get you more advantage then two pullies? If weight is a real worry, how many more scenario's can you accomplish with 2 rings verses 1 heavier pulley?

10:25 yes, just poke your eyes down into an active rope on tension. Kids at home, don't do this. Former Army Recovery Mechanic, ECN 226.

I see a lot of people use the rings. I wish morr uTubers like @caseyladel would watch this guy!
