Ok, in the most simple terms - a conifer puts on extra reaction wood on the underside of the branch which supports and pushes up the branch creating larger growth rings on the lower side when viewed through the cross-section. This is called compression wood. A decidous tree pulls the branch up this is called tension wood, when viewed through the cross section there will be larger growth rings on the topside of the branch. Is this a general rule? or are there some decidous trees that act like conifers and put on compression wood on the underside to force the branch upright? Cheers TC

Alisdair, do you have any days free this week? you got a motor with fuel in it? Can you get to Glasgow easy enough for say 8AM? Helmet? Chainsaw trousers and Boots?

Many times in this line of work we're felling trees where we have no escape route due to walls, buildings etc, which is why a tree barberchairing like that wouldn't be fairly tame. If that split stem had landed on your skull chances are you'd be well and truly dead from having your spine snapped at the back of your neck, at the very least you'd have a broken collar bone and dislocated shoulder. The guy should've used a bore cut with a holding strap or a sharper and faster saw, he didnt have clue what he was doing and was obviously a total amateur just playing at it. Good video though, thanks for showing.

Nerds?! The thing about SRT is its so easy its laughable, not only that but if your good with a throwline it gets you up big trees to your main abchor point 100 times faster than body thrusting/prussiking/ladders. You also feel less knackered when using SRT cause its all legwork. More tree surgeons should learn it. Especially people who are getting old and decrepit. I'd like to see Paulo Baveresco's frogging SRT system and set-up, looks more efficient than my basic version. This guy is using a pretty basic SRT set-up but it does the job just fine - [ame=http://uk.youtube.com/watch?v=6cGBUBVPJxY]http://uk.youtube.com/watch?v=6cGBUBVPJxY[/ame]

Know what your saying, the main issue is that SRT is hardly used in the UK because the trees are so small. When I worked in Washington DC of the 6 climbers in our office 6 used SRT without even thinking about it, the most basic system, pantin and Petzl right hand ascender with micro grap backup above the ascender. rope was always tied off with bowline at base of tree, no isolating on branch and running the bow up the tree. We were all using SRT cause the work demanded it, climbing much bigger trees on a daily basis. We dont have work like that in the UK, which is why SRT is only used by a few enthusiasts. .

Excellent Reg, The Lime removal was top quality, good controlled rigging and saw work. They'd make good demonstration vids to show trainees. What were you using for lowering? The Beech looks like a nightmare for rigging down if the decay is as bad as it looks. FWIW I'd be rigging very small and letting it run to ground and freefalling as much as possible. Make sure and video it - very interested to see how you approach a tree like that. Cheers for posting the vids. .

looks like a branch came down from the other tree at 48 secs and just missed him.

looking for work in scotland although ayrshire would be preferred
scotspine1 replied to Alasdair's topic in Employment
Alisdair, how come you still got that serial killer avatar? QTS have a big contract up in Helensburgh just now, they may need extra bodies. -
Are there any targets under the stems? What about funding for cable bracing? could be cheaper than the pollard option.
-
What was the original height and how many were pollarded to 4 meters?
-
Charlie, you talking about a Hybrid Black Poplar of some kind? .
-
Refresher? I know more now than I did then. Dont see the point in refresher courses other than its a good way for training companies to make more money. Good luck tho in finding other people.

Did the SAC course 5 years ago with Graham Watson, think he's left SAC now, which is a real pity as he was well respected in Scotland for the thoroughness and completeness of his knowledge on everything from propagation to felling. Anyway, the course then was pretty interesting, think it was 2/3 days lectures followed by written exam and thorough examination of arb equipment. You need to know your stuff, I think Petzl have info on their site about climbing equipment inspection. .

Jason, what are all those little drawers for?
-
Good pay. You ever find out anymore about the whereabouts of Jez Crowson?
-
Yeah but he'd be wearing a Treemotion right? the SWL is 100kgs, two climbers descending on a single line are gonna be well over that.
-
It should be the norm, its a very easy thing to do - setting up a simple rescue system for SRT, but anyone whose used a gri gri or Stop for that kind of belaying will know they are anything but smooth on the descent. Someone was asking what's SRT? - http://www.spadout.com/w/ascension-systems/
-
Agree with that Rupe, I've never once used a gri gri, grillion, figure 8, Petzl Stop or mini portawrap(probably the best option) for that technique, I just wouldnt trust the ground crew to get me to the ground safely. Not that my ground crew is bad, its just that there's no need for the belay device at the base of the tree as I wont ever need rescued while SRTing, what situation would you need rescued whilst SRTing anyway? Whats the half hitch for? always just use a plain running Bow.

Why does the council want a tree report? what legislation does it relate to?
-
Nev, this shot, the climber riding the ball/hook - were you using someone to set the slings and a separate cutter in tree? Thats how I learned crane work, havent seen anyone else use it recently. One guy would get hoisted up, set the slings, descend from the ball using his regular climbing line, pull his line out, then the other climber in the tree would do the cutting, branch gets lowered then repeat the whole thing again.
-
Was that when you worked for Eric Frei?
-
Any pics?

Not the best advice I've heard heard about crane work. Shilo, ideally, large tree crane work should not be attempted without an experienced person to guide you through your first attempt. I used to work for a company and me and 2 other experienced climbers were sent to do a 110 foot Oak dismantle using a crane, all the timber had to be lifted over a £500,000 home - none of us had ever done crane work before and the crane operator had only done one tree removal 10 years previous. After one overstretched pick the back outriggers on the 50 ton crane were 3 ft off the deck, its not a good way to learn. After that near disaster we forced the boss(who had 15 years crane experience) to come and show us how to do it properly.

Nice hat-rack

Huck, at 1.45 his left thumb is not wrapped around the handle when he's cutting, always catch myself doing this with the 200T - very bad habit. Ever used a 338xp? they have a little thumb rest for your right thumb, so much for 'always wrap your thumbs round the handle'. Anyway.....its a good vid.
