How would it get hot on the inside but not the outside when the outside is where all the friction happens?
-
Nice machine, that blue grapple looks seriously heavy duty too.
-
Agreed, which is why I dont shout about it on a public forum. What I choose to do in order to get the job done is down to me, some of those techniques and practises I would never recommend to a less experienced climber/cutter.

I would say its a Mimosa tree, and they arent hardy. Taking into account the cold winter, it might just get better on its own. Until next winter that is.

I used to use them, didnt get on too well. My local post office isnt particularly reliable either.

Thinking about switching my business banking to HSBC's Business Direct Account. Anyone use this or any other HSBC account? Any good or bad points? Not especially unhappy with my current bank, but since I moved to Cambs its now a hour and a half round trip to my nearest branch in Cambridge city centre and I have to pay for parking. HSBC have a branch 4 miles away and I can park the 18 tonner on double yellows outside. Sure it will be ok if I leave the flashing lights on, after all, I'd like to see them get a standard wheelclamp on her!

I have done large fells off spikes, for two reasons only. 1 To fit a tall fell into a short space. 2 On a job doing 4 metre pollards on large trees were I had to do 6-8 a day to make it pay. Not too sure why Murphy did those that way.

Nice.
-
Oh right, cancel that then. Not my dept. Hope the weather picks up, its bloomin awful here.
-
And some prizes?
-
Yup. See you there?

That whipping is a thing of beauty Tommy, you can be my whipping boy any day!

I quite like it, after all if the cap fits wear it! Might just get some new business cards printed up, Peter Haine Barbarian, Butcher, Rapist, Ravager and General Despoiler. Also Tree Surgery and Hedge Work. Roofing at Weekends.

The way I see it you would only be liable if the accident was caused by poor workmanship, ie the bracing was improperly installed and failed. If the installation is based on your advice then as per tree inspections it only covers what you can see on the day, and requires periodic re-inspection. Dont have any definative answers though sorry.

I dont agree. With the rope tied off you have one load/force, with the rope running through the pulley you have two. As you point out, this is mitigated by the redirecting of the load.
-
A good understanding of the engineering principles helps the arborist to understand the forces exerted on the tree by the rigging operations. A good understanding of tree bio-mechanics helps the arborist to understand what forces the tree will withstand. Both are essential, you shouldnt dismiss the physics too quickly.

Ok, heres where I was coming from. Rope tied to top of tree, load hanging directly underneath anchor = 1 unit of load Rope tied to bottom of tree, run through pulley and load hanging directly below pulley = 2 units of load. Rope tied to top of tree, tensioned for speedline at fall of 30 degrees to horizontal exerts a certain amount of side loading on stem. Rope as above but through pulley at top of tree and tensioned at base of tree exerts less side loading? but more overall force, although some of the forces are redirected. Rope run from ground level up to top pulley, then down again at the same angle, and tensioned from ground level so the tree is in the centre of an equilatral triangle = more force on the line, but most of the force is redirected straight down through the stem, so the loading on the tree is closer to my first example. I could be wrong about this, it is a genuine question.
-
Ah, glad to see you edited that.
-
Nice work Reg, looked very smooth. I take it most of the limbs were on the downhill side of the tree? I like tensioning the traverse line from the base of the tree, that seems to work very well for those tricky low limbs, but doesnt that increase the loading on the tree in comparison to tying the line off to the top anchor and tensioning from the lower end of the traverse line? How are you liking the new Yale climbing line?

Stack all the logs somewhere they can be stolen, I guarantee there will be nothing left in 24 hours. No access for a crane truck?
-
I'm still northerner at heart, but I'm only about an hour or so from London, what do you need?
-
Pfannner, although they are made by an Italian company called Krispy, who also make doughnuts, and you can buy them without the pFanner label from Nod.
-
I think they look Poo and you should buy some camp Red boots like mine.

Split ash from yesterday. Forgot to take any more piccies, left it as a mono for the creepy crawlies and for the client to grow a honeysuckle up.

I promised Richard some months ago, but my supply has just dwindled recently.
