practice, and more practice....try felling a tree high and practicing on the rest of the stump, you should get 5 or so practice fells out of a high stump

what have you been told your doing wrong?then we can mabee give you some tips,but as lee says practice is the way ahead.

my back cut is usually too high or too low i cant seem to find and even middle. and usually the hing im left with is to thin at one side and too big at the other

 

 

just a wee note my spellign sucks

Practice Practice Practice

 

......One of my lads puts a little nick with the saw both sides of the sink cut so that he can see the height of his sink from the back of the tree.

 

He does this as the tip of the guide bar tends to be lower when he is doing the back cut without this.

 

 

....but not sure if that would be allowed on course??

Only noticed your location....I used to live in Saltcoats.........

We were taught to put your sink cut in then nick both sides of the tree about 1/4" deep sit two small twigs in each nic. Then when you come around the back you can line the bar up with the twigs.

 

Its hard to explain by typing but hope you get the jist.

Mate of mine just did his 31 and had a similar problem, take note on the cut high and practice on the stump, he was asked to do it on his assessment. He also used a yellow crayon to put a line on at the right height till practice got it spot on.Hinge thickness - cut a little less then see if it will go, you can always take some more off, better than cutting through the hinge!

Over do your buttress cuts, then make sure the bottom of your sink cut is at the same level (you should not be penalised for taking your time getting everything level).

 

Its harder at first but try doing your felling cut with a pushing bar. It is actually easier when you get used to it and on 31 your felling cut should be the thickness of your side caseing above the bottom of your sink cut, you also end up putting in your sink cut and felling cut without having to walk round the tree. Getting comfortable with a pushing bar now will help once you start 39 etc.

 

When you start your felling cut dont be afraid to stop, leave saw in the cut running with chain brake on, and check your level/parallel. When you start cutting again just push the chainbrake into the tree to knock it of etc.

 

Try not to rock the saw, get it parallel for your hinge and keep it that way.

 

Like everyone has said practice, but dont rush cos every one you fell still has to be snedded! Get it right slowly and speed will come with experiance and confidence (on everything - not just 31)

 

Hope this makes sense & helps. Good luck.
