hey there therrin. what kinda knotch do ya call that.
on thing to keep in mind is that when you pace the face notch... keep it clean. im not able to draw on your pics so bear with me. when you back cut and the tree begins to hinge the notch obviously begins to close/ when the top of your face notch{the diagonal/hypotenous} meets the bottom of the notch{flat cut} thats where the resistance starts.when those two places meet the tree then begins to rip apart at the hinge wood. too much and you get the stuff stickin up in the middle. that stuff is an indication that there was an enormous amount of force acting on the butt{gravity/inertia} , the notch closed and the hinge wood tried to hold but the force was too great so it pulled the fibers from the core of the tree.no matter what other type of cuts or notches you may place on the butt its all over after those two points meet. you no longer have control of the tree. to eliminate the fiber tear youd use a bore cut or an open face notch. the open face is just what it sounds like. big and wide. 90degrees or even bigger. bring your back cut up a couple inches and start slicing that bugger level across trying to leave an even amount of hingewood all the way across. the open face will allow the tree to fall almost if not all the way to the ground before control is lost{hingewood breaks}
once youve become familiar with the way individual tree species react when their felled youll be able to use conventional notches and avoid or keep the tearing to a minimum by adjusting the speed at which you place your back cut. heavy leaners require faster backcutting because if you dont get the hingewood down to the appropriate thickness before the tree has fallen too far you end up with the fiber tear. hence.. a razor sharp chain, a well filed bar, and a tuned in and fueled up saw are necessary.
when youve placed your face notch in ..clean out the notch. make sure the angled and horizontal cuts meet EXACTLY. if one is further back than the other...the notch is only as wide as your chain witdh and will break prematurely{hope you understand that. hard to describe} then place you saw back in the notch. huskys have sights on the rewind covers{ perpendicular raised lines} make sure bar is snugged up against back of notch. that will let you see, providing the tree isnt lost due to hinge break, the direction of the fall.
keep it uniform and keep it CLEAN and youll be slammin down on target every time>
good luck.
