Bore Cutting the Hinge

Was just discussing this with someone so I thought I might put it up for discussion on here.

I find that bore cutting the hinge, mostly on connies, makes the beast go over more easily.

This is done through the gob side before doing the felling cut.

Your views will be appreciated:001_smile:

never tried it but i can see how it would make it go over easier. less fibres holding it up. any particular % of the hinge you cut away?

I do it to oaks for milling, but that's to stop the fibres tearing out so you get a cleaner full length butt.

On the odd occasion out here I have had the use of professional timber cutters for a day and they use that method; because,as previously stated, it maximises the millable wood.

Have bored hinge on willow stops that barber chair, also helps with leaners when bore cutting the back / dog tooth cutting.

I use it a lot felling poles, that way you get a better hold for felling without losing directional control by cutting the hinge thin to get the stem over

Ditto, I also use it if my bar is a bit too short to meet in the middle on large butts.

Yeah this is when I use it the most too!

I generally only bother on anything going for milling, but especially bigger or leaning ash, and usually couple it up to a dogs tooth. More often than not I'll make a small cut down either side of the hinge too, severing the buttresses to reduce the risk of tearing up the sides.

Handy tip though, don't take the same 660 out to do lots of bore cuts when the last job it was on was cutting big windblown spruce off the stumps without changing the chain first Long bar and low rakers make it a bit lively

I learned it from a guy who has been in the job a lot longer than I and think it is great for pulling over heavy stems that have no forward lean to make it come over .
