Try Cleveland Site Safe - they do some great buildings/storage

It would be a waste of time trying to get sunlight over the top of those - you would need to halve them to have any meaningful affect. If they will not listen to sense then do what makes you the most money

Sharpening, Oregon 410 - Getting to Proper Guide Depth?
Pete Mctree replied to FlyFishn's topic in Chainsaws
@FlyFishn how well are the bars dressed ? A very neglected part of the cutting system sometimes -
Simple surveys like this will always present poor data. There is no moderation for duration of usage of a saw ( months or years does make a difference), purpose ( arborist or cutter) level of training etc.

Chris is a more than capable individual and a hard worker too. Always an asset onsite, with a depth of knowledge and strong skill base. Hope you find something soon 👍

You are correct John, friction is not relative to area. However a larger rope will have a different (greater) coefficient of friction (different mass, grip etc), so less force would be required on the cam to hold you up there (let’s just pretend they are identical in every manner but size). This is all really noticeable when you are using them. So, I still disagree with you - a larger diameter is not an issue as long as it is within the parameters of the device. I think this thread has run its course for me.

I just feel sorry for the original poster, who wanted some simple and important advice on a crucial piece of kit. He did not need to hear misinformation or hearsay. Really drags the forum down to the same level as Facebook

So, when using the 13mm wirecore did it ever slip or creep after it had grabbed whilst still weighted ? Do you understand that the cam grabs on the sheath and does not rely on any major deformation of the core? And that a significant amount of the friction is from the cam pressing the line against the body of the device? This means that a thicker line will have more grab/friction as opposed to a skinny 11mm one….. You follow?
-
What diameter range did the manufacturer specify for your grab - never seen one that maxed out at 11mm before ….
-
And that makes them unsafe - a single person’s opinion? I have met Reg several times and he is the real deal for sure. I may be wrong, however I thought his issue was with the wire core itself? if you had an issue with a rope grab, then why not the prussic too? Perhaps you need to go back olde Skool and use the becket hitch ? Yer full of shit dude
-
Whatever John - do you not think that the geometry of the cam is not optimised to the diameter of cordage that it is constructed to work with? Perhaps you have not been using it as designed? As for breaking spring - it only functions to prevent the rope falling through the grab when not under load and would not cause the device to let go under load. I think your post is poor to be honest, as it is neither informative or accurate- I’m done with this
-
They are a safe and reliable device when used correctly. They grab better with a thicker rope, as the cam has a bigger surface area to contact as does the body. As for the spring, well the item is defective without it, so why would you use it?
-
In the video, you did not “load” the grab, you simply moved it up and down with the body. If you pulled down on the maillon, which moves the cam against the rope, it will lock. Try it.

I melt loads of polyprop every year. Lots of natural crotch rigging, pulling stems over and generally abusing. At approx £85 for 220m of 14mm it is relatively disposable & saves my decent ropes for when I need them.

Really don’t like jam shed, but after this thread had to detour and drive past Lidl 🤪
-
Lidl do some stunning wines for the money. They do a good couple of bottles of Shiraz as standard & a good Rioja & Cabernet too. You need to look out for the occasional appearance of the second fleet label - the merlot & Shiraz are stunning
-
Bloc is fine as long as it can take 7t plus. just be careful what you anchor it with. Wire strop probably the way to go, but they are not kind to retention trees. Tennex is an option
-
@MattyFlooks like your going to busy for a bit !
-
You have to factor in the rebuilding of older saws. Rubber components degraded by petrol do not like the change ☹️
-
If you put some kind of microswitch on the front handle, it would inhibit use, especially shedding where the front hand moves constantly. It may work for a 2nd rate arb who just cross cuts or works by a chipper, however the saws are designed to be used ergonomically & stupid “make it safe” fads are only going to detract. Safety is increased through good training and application of common sense to that base knowledge. Be careful what you all wish for, - remember the fiasco with 2 rope working !

Fraxinus excelsior ‘Pendula’ and Ash Die back.

They are suffering like every other ash with ADB around us.

Is all one handed use unsafe ?- it is still taught I believe at extremes of reach in appropriate situations.

Training is always an issue. The employer (as the customer of the training companies) has shaped the product. They want an employee to learn as much as they can, in the shorted possible time at minimal cost, so what you get is this current farce of low skilled workers. Alarmingly, the current certification is no longer a certificate of competence & the employer is supposed to assess whether they are fit to carry out a task. Sadly I know of many employers who are not fit to use a saw themselves professionally, never mind dictate to others. I guess what I am saying it that for me the system is broken, however whist the industry needs staff, trained cheaply and insurable, then that is all the system will ever produce
