felling cuts

[Dean Lofthouse]

I did not mention leverage.

 

I did not say you did !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Please explain how a larger gob can "compromise balance"?????

 

sorry for late reply as been away! :blushing:my bad mate. poorly worded. just leverage will do nicely. nothing will change the overall crown weight distribution of the tree [balance]. it is down to your personal judgement to take correct measures if theres a chance itll sit [ropes, wedges....] as you well know.

If you put a big gob in and the tree sits back(i.e. wedge falls or being knocked out from felling cut), there is a bigger risk of this happening oposed to a small one, alloving the trunk to hold the tree. It will be easy enough to borecut from the back and insert a wedge and knock it back up again...

agreed mate. more control over the situation and no loss of leverage.

Old thread I know, but can anyone tell me what a 'bore and sweep' cut is and when you use it? I've not heard of this analogy before but know it's in the new version of CS32?

Basically its used during the felling of larger trees when your bar is to short to go straight across conventional style. You form your gob in the normal way and then plunge the saw into the stem just behind where you want the hinge to be formed. you then sweep around the tree to the other side removing holding wood as you go until you reach the other side of the tree and complete the formation of your hinge.

You also use a bore and sweep method when doing a plunge cut through the centre of the hinge forming a "letterbox".

I hope that makes sense.

Here is an animation of the first "bore sweep" method I mentioned...
