These are also good cuts for dealing with leaners.
PA, most these guys are pros but what bitzer said is best for you imo. make an open face and do not cut any farther than the face. next bore straight into the face to gut out most of the hart leaving a couple inches of the hinge on both sides. finish with your backcut and don't play with it, cut it quikly to the hinge leaving not more than two inches. less is better imo. do not try to stump jump white oak, it is tricky even for pros. they will split if you leave any hart, that why I,m telling you to bore the hart first. it is tricky to try n swing them, throw them in the direction of the lean if you can. I hope I have explained this in a way you can under stand. I don't seem to have any pics to show you. keep talkin to us till ya think ya got it. white oak here chairs easy and I don't want ya to get hurt.
depth of notch depends on lean. biggest thing, line up your cuts and don't cut deeper in than your face. I know ya gonna think ya never gonna get thru the back in time, that is the purpose of boreing the hart out.
I wouldn't make the notch no more than 1/3 tree diameter, less if heavy lean. make that top cut 45 degrees or more, you want to let the tree fall a good ways before the notch closes, that's when all the stress occurs. you can try taking out a piece top and bottom so it won't close till the tree is about down. if you cut deeper than the notch then the crack closes up and that is when you will have tremendous stress and the tree splits. sorry for the multi posts, i'm just trying to help you understand whats happening when a tree chairs.
TS....Bitz and Gologit given ya the best advice ........watch the height of ya back cut and ifn ya gonna plunge and leave a strap then watch when ya release it as it'll go quick and imo release it from under not over ...........The sketch posted by Md was a humbolt face with a snipe but the methods described will work with the conventional or open face too.
Prolly best to ignore my video. I put it up as an example of how to bore behind the face from the side. I extended the gunning cut past the face on the near side intentionally to turn the tree and bored out the back leaving a triangle of holding wood before cutting the strip. I am not confident enough to stand in front of a leaner I've faced and bore the heart out thru the face. I will leave that to the real pros (Gologit, Bitzer, Jolly, Treeslayer, Cfaller, Busted). I like to try to talk like a pro, but am in actuality a pimply faced kid in my mom's basement
definetly under, how ever I don't recommend the plunge and strap to any inexperienced faller. it never been my preference anyway.
Keep in mind guys, he's just cutting 16-20" dbh oaks with a 394xp running a 24, by the time ya get a decent notch and hinge, not a lot of room fore a bore, and way easy to overcut.... the bore... wth's he doing with a 394, I want a 394. Somethin's not right. I'm gonna go eat worms.

Not sure you're experienced enough to run a 394. Well, maybe with safety chain:jester:
