and so you should Do you really read Modern Arboriculture? if so your probably the only person who does, most people in treework own it, but never read it. They just have it on the shelf to make themselves look educated. The Demons of D is my favourite part.

this thread is pathetic

sempervirens

brake hinged in two places, like the ms200, good sign. Looking forward to reading a review by a working climber who has used this saw daily on large trees for at least 6 months, any other type of review will be worthless.

These supergiant turbines emit a low level hum that affects children's development. HEALTH - West Lincoln Wind Action Group Tell the windpower company to position the turbines 500 miles offshore.

I can 100% guarantee it.

very fake, very stupid

The Isuzu Rodeo and the Nissan NP300 (slightly modded D22) have a 3000kg towing capacity. On the NP300 - this pickup is available in the UK but Nissan seem reluctant to market them, no doubt due to the public relations disaster of the D22 conrod issue. The 2.0 litre engine size of the Amorok? have they pulled the engine out of the Passat and tweaked it for towing?.......suppose if they've got the gearing right it should be half decent work vehicle. But at what cost? £20,000+??? no doubt. .

more information about the site where the tree is growing please

By doing what you are suggesting aren't you are making the tree more hazardous for the climber?...by encouraging decay?...which surely would reduce the structural strength of a tree which is already hazardous? Actively reducing the structural strength of a tree you may have to rig off one day may not be such a good idea?

Tried it once, its pathetic. Probably the worst hitch I've ever seen, Bachman should be ashamed.

Your post is riddled with contradictions. You believe heavily in nature's capacity to thin the human species but you would prefer to interfere with it using eugenics. Eugenics - Wikipedia, the free encyclopedia

The Greens believe in better planetary management. Have you considered becoming involved with them? maybe become a green activist? Its not too late to make a difference.

remember by using a pulley nearly all the friction is displaced into the friction hitch. This isn't always a good thing.

seen Bingham's arbbike rig? he's managed to find room for a chipper - [ame=http://www.youtube.com/watch?v=SrAV4H0FiEk&feature=mfu_in_order&list=UL]YouTube - BIKE CHIPPER[/ame]

And so you should, it'll happen one day, it'll start with a quiet tapping then..........I can't say anymore beyond this point other than its horrible what happens next....truly horrible, be prepared. Still, mine went at 96K miles so you could be good for another 16,000 miles

The problem is with the con rod big end bolts, there is a thread on Nissan Navara.net that runs over 100 pages specifically dealing with the d22 engine failure issue. the bolts are permanently damaged during the angle torquing phase of their installation, also the lack of quality of these bolts means that they pass through their elastic limits (meaning that when undone they should return to their exact original size, specification and condition) into their plastic limits (meaning that permanent changes to their dimensions has occurred (due to being overstretched), and to their molecular makeup (causing graining to take place, a form of work-hardening, leading to a critical catastrophic failure or snapping after further use). Mine went at 96K miles, it'd been a great workhorse up until that day. Nissan UK put a new engine in free of charge despite it being 6 months outside the extended 5 year warranty. Since the new engine I've done 10,000 problem free miles.

very good Rich, great labour saving system, you should try it SRT if you get the chance, this guy is using a frogwalker set up on SRT - [ame=http://www.youtube.com/watch?v=97KC7OhVZrY]YouTube - Frog Walker[/ame]

Because with SRT your increasing the risk of catastrophic failure of the your lifeline due to the fact it runs from the top of the tree to the ground with your weight on it and your spending a long time pruning and cutting branches thereby increasing the chances of cutting through the line. All it would take is for you to forget about this section of rope for a split second and slice through it with your chainsaw when finishing off a pruning cut close to the main stem. With DdRT the working part of the rope is always above you. You can see where it is, with SRT or DdRT off SRT the working end of the rope is 80ft below you tied round the stem waiting for one of your groundies to cut through it with a pair of loppers as he goes to remove some epicormic growth. or..... your dropping branches out of the tree, some of them are falling in near where the SRT line is tied off, some of them get into a tangle and your groundie takes a Silky into the mess and slices through your running bow or belay system by accident. have you ever heard of the saying, 'is there is no end to human folly?' its very apt for anyone considering using SRT for work positoning. Isn't there an alternative to the trunk belay/tie off?

For me DbRT is more advanced than SRT (trunk tie off) for work positioning due to the fact with DbRT you are constantly working a loop which you have complete control over. Unlike SRT (trunk tie off) work positioning - once your line is over the top anchor point you are at the mercy of the huge length of rope which descends to the base of the tree, you have no way of knowing that this section of the rope is completely safe during your climb which on a large prune could be well over 6 hours work. For me, its this unknown element which has so far ruled out SRT for work positioning. Plus the fact that nearly all my jobs are removals. Having said all that I regularly use SRT to ascend into the tree using the trunk tie off method which is an excellent way of getting into the tree, its just not a good way of working in a tree in my opinion. Very few American climbers use SRT for work positioning apart from some vocal internet users determined to make people 'see the light' (not Cary) .

keep practicing, take it slow, there is no point in moving out onto a branch fast especially in wet weather, or the branch is broken or has dying bark. The other reason why you should branch walk slowly is because you may dislodge a hanger or a dead branch which could fall onto a street or targets below. There will be times when the best option is to use a polesaw Sometimes you may be able to swing out to a branch but thats for another time. If you want to get really good at branch walking you'll have to practice outwith work. Just a few pics from work -

The so called 'hanger' didn't fall onto that other branch and graft itself on to it, they were already fused a long time before the 'hanger' was cut.

never knew you were a black belt in origami Mick....nice one

right, thats good, lets get back to real world where groundies are well known for their unpredictable and erratic behaviour seriously though, I get your point Ben, but you'll need to do a lot more convincing for SRT work positioning to become accepted as the norm for treeclimbers.
