First one is perfect! What happened with the third one? It looks like it broke early end fell towards your foot in the pic? Some pulled fibres in the top of the hinge and compression in the bottom of the pic? Was it a sideleaner? If it was, did you bore and put a wedge just behind the hinge on the compression side? The ratio is usually 1:3 in strength between compressed and pulled fibrestrength. Eg fir has a pulling strength of about 600kg but only 200 in compression. Just a thought and wanting to share if you didnt know this. (Yes newly aquired knowledge.... Always done it but never knew the theory behind...)

Sorry if I confused things... If you are felling trees for logs (no waist high arbstumps) you tend to go really low on the trunk where the fibres often (at least on fir trees) arent straight. Cutting low backcut in these circumstanses ensures that there is enough holdingwood left in your hinge as the grains grows at an angle to your gob and cutting high sometimes means that you only have half of your hinge with intact fibres. This is probably not the case in the photo...so in conclusion; get youre backcut level with your felling cut and you are always correct! I have been in this trade for a long time but due to a change in company policies I did my swedish eqvivalent to my 30 and 31 units last week. Great to get a freshening up on things!

Looks good! Better would be if felling cut is level or slightly lower than bottom of gob or else you might end up with a step cut...

A word of warning to the two of you.... Don't start! Its hard to stop....

Looking forward! We love pics!!!

OOOPSSS! DON'T OPEN YOUR MAIL!!!! It might contain a virus or fungalsphores....

I was only slagging mate! That made me giggle!!!! -
Sorry Max! Stick some photos up and we will tell you if it is Phellinus, Ill try to get around to take better pics of the tree, but its usually dark when I pass it. Scleroderris canker - Wikipedia, the free encyclopedia Gremeniella is a nasty little bugger causing lots of damage over here esp after mild winters (or winters with snow in the trees)

Nice and clean "gob" but you need to practise on youre bore cut and make sure the hinge has an even width the whole length. Ideally the gob should be at least 70 degrees and 80% of the width of the DBH and the hinge thickness should be 10% of that. Example; Tree has a DBH of 40 cm, the width should be at least (80%) 32 cm and the width of the hinge (10%) 3,2 cm. Its important to have the hinge even to properly work as a hinge, otherwise it might break of and make the tree fall slightly sideways insted of were you were aiming.

Youre spelling isnt really up to scratch, is it? -
Yup! Sounds like your boss has passed on the stuff I taught him.... As a groundy I had to teach new climbers to work efficently...and that ment the whole operation not just their part!
-
He has left the country or hasn't he?

Snowing at the moment... last week was really mild (-5C) seems to last a few days more:001_smile: Greminiella might do its thing and there is another one growing on old Pine that I cant remember the name of. Other than that there nothing in my area as far as Im aware.

I only had crappy IPhone pics... Couldnt even get proper focus on the higher ones.... But if you insist Sir!

Ive just found a willow with FB all over it. Main trunk branches and old pruning cuts! Haven come across such a videspread infection and tree still standing before.
-
Or battery powered ones...
-
I´ve had the idea in the back of my head...but never got around to do it. Looks really good! My consideration has been wheter i could give it a whack or not...do you just use it as a stop or do you actually wedge stuff?

So was it as hard as you feared? Or did you just got your act together and buckeled up? -

Good luck tomorrow! Dont rush anything, remember its just a test to see if you have understood the techniques and know how to perform the various tasks in a safe manner. ITS NOT ABOUT COMERCIAL SPEED. Im retaking all my units over the next couple of weeks due to a change in company policy.... They are paying for me to take the NPTC-units i already got, because they want me to be able to show a swedish proficiency certificate! Looking forward... always good to go back to basics.... Remember....HAVE FUN and ENJOY! It just makes things easier and releases pressure. Dont forget to TALK to the assessor as it gives you an opportunity to show him that you know your stuff in theory.... Back in the days when I did my climbing unit my assessor fell asleep in the grass, I think he knew I would pass.... -
This was done at super squirell speed! Started for 8, preparing (cutting) for the stein, installed the climbingrope and dropped one big branch then had breakfast as we didnt want to work in the dark (God bless streetlights...). Everything went smooth and by 3.30 there were only logs and trunks from yesterday and today left.... they will be shifted on monday and placed in "my" conservation depot, where we place all oversized logs and trunks, esp the ones with interesting or rare lichens, fungi and/or signs of beetles and such!

HC and a short VT. I prefer when its cold rather then around 0 when the ropes frezes up. When its cold its important to store the kit (not the harness though, ouch) outside during the day so it doesent go from cold to warm or vice versa. I normally have at least 3-4 pairs and change during day as they get wet.
-
At that angle it sure looks allright, but it would have taken all of the above mentioned targets... besides, ever tried raking up a chrashed out poplar in two feet of snow? It just have to wait to spring....
-
Its -23C now...(Just had a look) mind you we had -6 yesterday morning thats why I did the 2 poplars now. I needed the tree to be able to "bend" as I needed a few branches to twist and go sideways to make them fit and/or swing... The cold weather came in during the day and we could really feel the cold coming... we had to hurry and finish the bits where we needed the wood to be still soft. Poplar just snaps when its really cold, eventhough it takes a couple of hours before the wood changes temperature. The snow is actually frost building up as the temperature dropped, my rope got all frosty... nice looking, but hands turn wet and cold when your sliding your knot on the rope and melts the frost.
