Mike, you were pushing the 'knowing what you can get away with' card to the max in that vid matey. All things considered though, well done to you and treequip for getting what sounds like a hellish tree down in a tight spot.

if you ever needed proof that kiwi treeworkers are better than the rest for christ sake dont watch treequip's 'bombing out' vid it's quite possibly the greatest spectacle of rank amateurism ever committed to digital video it doesn't matter who it was that was climbing either, mike hill (kiwi) was the gaffer on that job. The whole approach was as pathetic a display of half baked treework you'll ever see, in fact it should go to the top of the guiness book of records 'worst treework ever seen' category, replacing all of old murph's vids.

peter, the pic with the high sides on? do you have a sideview pic? also, done a d22 kingcab yet by any chance?

Rich The business model wont work, franchisees or affiliates would need to invest financially to prove they were serious because it'd be a huge risk on your behalf to buy people chippers and tip trucks, tools etc, they (the franchisees/affiliates) would have nothing to lose if the business failed, but you'd be left seriously out of pocket. Ultimately, once the potential franchisees had used their own money to buy a chipper, tip truck and tools etc they'd forget about supporting your venture and instead go out on their own. Isn't there another way for you to help support ex military people that doesn't involve financial risk?

nice work Ian, good job, pine looks like a Monterey, P. radiata

Wonder how it feels to be a snitch like that chainsaw assessor? a curtain twitching snitch at that. All sneaky like, crouching around the house on his hands an knees, taking photos and phoning the Health and Safety Executive. Freak. What's wrong with these people? You could understand it if the guy next door was about the fell an 80ft Beech onto a primary school full of kids, but the guy up the tree was just some subnut doing what subnuts do. These clowns exist for our benefit, the sole reason for their existence is to show them to our kids and say, 'see that person son, that's a complete idiot, dont be like that'.....'ok dad'. You dont go grassing them up to the police or HSE for christ's sake. The HSE dont have the monopoly on health and safety, it's a state of mind, you either got or you dont, the guy up the tree didn't have it, but that doesn't mean he should be fined £4000 for what is a relatively minor infringment.

the way I see it you dont have a choice. If it's decent work and your guaranteed good money within a month or so then it's all good. But......if this company starts messing you about with payment then forget it. Let's say the payment starts to creep into 2 months or even 3 months, it's simply not viable, small companies like we run (you and me that is) simply cannot afford this kind of wait for payment.

cheers mate, tried to make it clearer in the diagram below. If you look at the photo of the snapped stem you can see parts of the tree where the timber has sheared downwards towards the rootplate. By removing the centre of the stem when making a bore cut there's a risk of the timber having a shear failure due to the excessive tension being created at the holding wood (strap) as the it's displaced from the centre of the tree. Hope this helps.

Frankie, here's what I mean by 'peeling' or the stem splitting down as you make the bore-cut (see pic). You need to try to imagine a climber tied round the stem just below the cut, if the stem splits like in the pic your going down with the top of the tree. Giorgio and Highscale, I'm not saying it will happen, I'm saying it could happen. In Giorgio's vid he is not on the stem he is cutting so it's all good, but if you are on the stem it's maybe not such a good idea.

Frankie I dont mean the bark peels, I mean the timber splits down the stem, sometimes 'peeling' is used to describe this scenario, it's the opposite of a barber's chair. Will try to do a diagram on Paint and post it sometime soon to explain exactly what I mean.

Sounds good, confidence is half the battle. For a bore/release cut in the tree? make notch (not too big), bore in using the pulling chain side of the nose and then use the pushing chain to leave a good size parallel hinge (or take saw out the bore-cut and flip it round to use the pulling chain to finish the hinge), cut back leaving holding strap then make final cut like you did in the vid. .

Hope you can translate this into Italian ok Giorgio..... Just a few thoughts. I've used the bore/release cut about 3 times in 15 years of climbing. The last time (about 10 years ago) was on a heavily leaning Eucalyptus top and it was only after I'd felled the top out and got out the tree I began to think properly about the cut and understand how dangerous this technique could be when climbing particularly when used in trees that are known for splitting ie Ash, Poplar and Euc. The first couple of times I used it was on tall thin trees (Oaks I think) with leaning or heavily weighted tops which were being rigged, like you I was trying to avoid barber-chairing and also avoid been thrown about on top of the stem with a saw running as the stem kick-backed and the rigging caught the tops, I made a notch and then a bore-cut then put the chainsaw away and use the Silky handsaw to cut the holding wood at the back. I assume you did a bore/release cut because you thought there was a risk of the top barber-chairing if you felled it out in the normal way with a conventional notch and back-cut? My main thought on using the bore/release method in a climbing situation is that the stem could split and peel down as you make the borecut (as you displace the tension to the holding strap at the back). Lets say you were tied into the Poplar at 1.25 in your vid below the cut with a flipline and climbing line, now if the stem split and peeled down as you made your borecut it would lift/lever your flipline, your climbing line and you right off the top of the stem sending you down with the top of the tree. A defect below the cut could also trigger a split/peel failure as you made your bore cut. There are ways of avoiding the bore/release cut in climbing (in my opinion it should never be used but other people will no doubt feel differently and feel perfectly happy using it) You could've just climbed up higher and cut smaller bits off thereby negating the need to fell such a huge top out. Another option if you really wanted to use the bore/release cut would be to strap the stem below the cut like some people do to avoid barber chairing, but the strapping would have to be very strong (two big ratchet straps?)to make a difference even then it might not work at preventing a split and peel down. The strapping could also apply to taking the top out using a conventional notch cut and normal back-cut but this time put the strapping above the cut to avoid barber chairing but let's face it this type of strapping is almost never needed in treeclimbing and it'd have to a be a very specific job that would require it ie Graham McMahon's Tahune Day 3 vid. .

giorgio, great work, sorry about Euro2012! ha ha why the bore/release cut at 1.25? there must have been other options. From my point of view it's a dangerous method to apply when climbing, having said that the fact you were tied into the other stem made it a lot safer. .

Can sometimes get bored of Spain's religious passing/90% possession style especially if they dont score much but they were very watchable tonight, glad they beat the Italians as well, Balotelli and Pirlo were totally shut out of the game. All kids should be taught to play like Spain, if your gonna play football, play football and learn to pass and receive the ball properly, excellent team, deserved the win.

Good luck to your friend and his venture, the market for lowering devices is saturated. Unless he can improve on the Buckingham Portawrap 3 he's wasting his time. It's is an arb design classic, that rare combination of something in treework that not only looks right but does the job right with the minumum of fuss.

Terrible for all those involved. You can see how the metal failed in these pics. This type of failure just should not happen on these machines.
