Tell your wife to stop projecting her own rude interpretation of the post title onto you....that should sort it

Well said joe, Steve and beezy.

I enjoyed the video and I agree that it can be very useful to see what not to do, if you like!

This thread is a joke,the video is awsome and I found the experiment to be hilarious. Cannot believe the arm chair arborists are trying to find criticism in something they would never do. No one would do this in a real scenario and I love it was done in a controlled environment by professionals and not another you tube clip gone wrong.

 

Thanks for the vid guys,keep up the work and I for one want too see 'what if' videos.

I have also had a good laugh at the pissing in the wind from the desktop experts who probably have spent most of thier career pollarding plane trees.

 

With regards to your comments above, if someone has developed the ability to think critically they're free to express their opinions, regardless of their relative experience in treework. Put it this way Cody, Stevie Wonder could've seen that rope was gonna snap.

 

I'm not a desktop arborist, and neither is anyone who has posted critical comments in this thread (apart from Stevie Blair but he's a very wealthy man and can afford to be one, kidding Stevie )

 

Australians/Kiwis and Australian/Kiwi based climbers, you dont have a monopoly on big tree work. This is a Redwood we worked on recently about 30 mins drive from Glasgow. A lot of people on this forum dont post pics and vids of their work because they've nothing to prove, especially not to thin skinned Aussies/Aussie based climbers who can't take a few words of criticism.

I did not realise that there was such a thing as irresponsible rigging and that people may be offended because we did not use shiny pulleys and double braid rope.

I have enjoyed reading through peoples differernt takes on the set up and reasons for it, I have also had a good laugh at the pissing in the wind from the desktop experts who probably have spent most of thier career pollarding plane trees.

 

 

Codz, where is it written that people took offence?

 

As for the desktop plane-pollarders comment....why would you say that?

 

We cant all like the same thing, that's just normal.

You need to post a pic of the Redwood from a different angle, I can only see the little one next to the house, the big one is behind it I guess.

Hey guys

 

There's no need for anyone to get worked up about this. No one likes being told they don't know what they're doing, so it's not surprising that comments like...

 

that rope was never gonna hold that timber, there would've been near 25 ton of weight as it hit the rigging, it fell a good 12 feet before it locked up then the rope snapped. Factor in weakening effect of the bend radius of the loaded rope as well and the 25 ton breaking strength is severely diminished.

 

As a workshop it was totally pointless as an advert for an arb equipment supplier it would make me doubt their judgement when it came to asking for advice re rigging.

 

It was a waste of a good opportunity to display some proper negative blocking using proper arb rigging gear.

 

or Mr Blair's input:

 

It just showed they didn't know what they were doing.

 

The minute I saw that big shackle I thought, there goes half their rope strength, and then tying it round all those trees ha ha!!

 

...will end up in argument. I try to be careful on here to avoid criticising other people's work, until I really understand why stuff has been done. In the comment above, you suggest that there was around 25ton weight as it took up. Leaving aside the fact we should be using force not weight, we were using doubled 25t rope so if you assume that we lost half strength for the bend radius we were still almost on the money... I still believe it was close. Guess you had to be there, see the aftermath and examine the gear. And it didn't 'fall about 12 feet' - the rope was installed fairly taut. What you see is the PLANNED extension in the rope (see my previous comments in response to Stephen Blair's misunderstanding). Obviously it didn't work - but a large group of experienced tree workers thought we had a fair shot at it.

 

Re. your later comments, however, it's hard not to be slightly offended. There are many reasons we set things up like that, not 'proper negative blocking using proper arb rigging gear' and I can explain all of them in excruciating detail.

 

It's interesting that most of the people who specialise in this sort of large tree work tend to end up ditching the 'proper arb rigging gear' and working with heavy 3-strand and natural crotching where possible. When I moved up to the hills I made the mistake of sneering at them - now I understand why they work like that. Just check out Graeme McMahon's videos on YouTube - there is a time and a place for shiny rigging pulleys and a time and a place for 40mm 3-strand! What we were demonstrating in this workshop - and one of the things I will be covering in my presentation to the Arb-Australia conference in April - is being able to recognise the difference between them.

 

RC0, I mentioned before that I kind of agreed with your criticism that it had little scientific or practical worth. A significant proportion of my work is removing trees like this as a contract climber - even if it hadn't taken us half a day to set up that snatch, you'd never do it on a job site. Surely, however, there is a place for having a crack at something like this when the (rare) opportunity presents itself?

 

Anyway, I'm not on here to make enemies, and to be honest I find these online disagreements kind of exhausting, except where they are backed up by reasoned argument, and result in some sort of worthwhile conclusion. So, again, apologies to anyone who didn't like the video, and we'll try to get it right next time.

Joe as much as I enjoy your videos and work I really think your video just comes across at the wrong angle for some, don't get me wrong it's pretty cool! But! It was an experiment that really only was ever going to end one way regardless of what gear you were using. You've only got to calculate how much force is generated by a 1ton section falling on to a rope from say 2m, its crazy to think you still think it was close??? You could do that setup a 100 times over and it would still have only one outcome.

 

But I'm not going to get involved in an argument, everyone is entitled to there opinion but ill stick to my guns and say I do still agree with Tim (scotspine1) on this.

 

 

Stay safe guys
