We Break Fence End Assemblies! What Fails?

- In this video, we fool around and find out by purposely creating fence end assemblies to fail and testing how they break. Learn from our mistakes and avoid these common fence assembly errors for a stronger and more stable fence. Save time and money by avoiding these mistakes and get ready to build a fence that lasts!

We use H assemblies. 100mm NB Gal pipe posts driven in 1 mt. 3 mts apart. 63 mm horizon gal pipe . 1/2 inch gal brace. All welded.
Fences strained with the tractor. The end assembly does not budge. It is over kill but there for life.
As 52 years contract fencer and stockyards builder there is no 1 end assembly.
Ground type, enviromentals and seasonal challenges dictate what we use both in design, materials method.
The biggest mistake anyone makes fencing is over tightening, under tightening wires.
Pro tip-Any end assembly or corner should be set with a bias to the opposite direction of the tension, how much is a variable that depends on factors such as Soil type, seasonal moisture.
Ps, earth rammed
Posts no matter how deep move far more than posts set with a rammer…….
Totally mate. The objective of this one was to make ends that were guaranteed to fail and demonstrate how. Cheers.
Very interesting I’m a fencing contractor haven’t had any experience with that last strainer assembly with that floating foot and found your video very informative 👍
Good video Tim.
I'd love to see another one where you compare different types of end assemblies that are recommended by contractors and manufacturers and measure the load applied to them until they fail.
I know there are many variables but I find it curious that manufacturers give a strain rating for wire but not a complete fence.

There are so many variables. The soil the fence is in can make a HUGE difference to it's performance. Testing these to fail is very difficult. I have an old video I never released on just that, but due to the tractor not being powerful enough, the video was inconclusive. Very dangerous too. But I could have a look at doing it with some more matchstick posts.....
May be would be interesting to see same test on mega anchor assembly
Impressed with the last set up
Yes but its getting more complicated and heavy in construction to make them super strong. The whole point of these assemblies i thought was that they are simple to construct with bare minimum materials.
Very interesting. Where I am at we have always used the H type brace which is a post between two posts and a brace wire from top of one post to the bottom of the other post. Will have to try this.
We call that kind of assembly a "box end ".
The physics at work in a H brace/box are the same as the last end assembly tested.
@@johnmorgan-fw3kc Same in all three. Short H, Box, Rail assemblies jack too. We left these out to avoid confusion. I'm feeling like I need to do one on Box ends now.....
Where can you buy the cable and end block?
Do a box assembly with a strainer at 600mm and 1200mm deep to compare. Might need a bigger winch! Also be interesting to compare a box assembly with a short top rail.
Geez I used to put 250mm posts 1800 in the ground with a stay to bottom of next post
You pobably didn't want them to fail. We explained pretty carefully that we designed these to fail eh?
Do those floating assemblies work for taller fences? (I have 2m tall windbreaks)
In a vineyard here. Full setup ruclips.net/video/ZdGlB1_99YY/видео.html
@@FarmLearningTimCheers, will get my hands on a couple for the next one I'll build.
That's a lot of effort just to show that the brace under compression can be a strong assembly, when you make all the components extra heavy duty. The video clearly shows that this setup will pull the corner post vertically out of the ground (if the foot of the brace doesnt give way first) . So why didn't you include a H box setup, with a wire brace under tension, for comparison? The H box assembly wants to pull the main corner post horizontally through the soil, it is a superior setup and doesnt need to be constructed anywhere near as heavy duty, to be just as strong. The main thing with the H box assembly is its strength comes from the tension in the diagonal brace wire, so it will actually get stronger when the assembly and brace starts to tension up under load.
I’ve done videos on box assemblies before. This one was about stay assemblies.
Id like to see how you build the last assembly from start to finish including a gate on the other side and the tools that are used preferably with hand tools.
Cheers a great video that was
