Heavy reduction

[spuddog0507]

did a heavy reduction today ? logs cut 6 x 2.5 O/S, 4 x 3.7mtr sawlog and 5 x 3mtr chip + top, tree was 1.24 mtr across at the bottom so pretty big for UK,

Hi, 

Question from an FNG here, I’ve seen this on a few stumps whilst walking around my local forest, and I was about to take some pictures and start a new thread to ask about it, but your photo illustrates it perfectly. I see you’ve cut out the center of the hinge (with a bore cut from inside the gob?), can I ask what that cut is called and what kind of situation you’d use it in? 

 

Many thanks for any knowledge you can share.

A technique used where the chainsaw guide bar is smaller in length than the diameter of the tree. Hence you 'bore in' to the centre of the tree from the middle of the sink-cut / hinge and then, hopefully, match up when you bore in from the sides.

 

Hopefully someone else can explain far better than I having not used the saw for...a few years  

 

Cheers,

Paul

Not only for a shorter bar length, it is used to weaken the hinge enough to reduce the pull needed to get it over, and reduce fibre pull for milling wood.

Makes perfect sense, cheers dudes.

Ok, thanks Paul.

 

As Peds observed, it’s standard operating procedure over here.

 

The back cut does not necessarily have to match up completely (height wise) with the keyhole cut.
