Interesting on the wood wasting point. I’ve been putting the top of my face cut where the root flare is almost gone because I thought the flares got trimmed off anyway...wrong?
Lining up bore cuts is tricky business. I dropped a 28” DBH ash (big tree for me) the other day that had a hard lean. Face cut was nice and straight, missed lining up the bore cuts by 1.5 inches and made an ultra ugly stump. Bored from hinge out to set trigger, she laid right where I wanted it but it was ugly. Lost about 3 feet of the but log because of thick hinge and my face was too narrow. The humbolt kicked it off the stump before the hinge fibers had a chance to break rather than pull and caused the butt to crack

...fail. If I had my 28” bar on it would’ve peaked out on the other side of the tree as I set my trigger hold wood and given me a little help in lining up the cuts. Sucked, first bore cut was perfect, flat with the hinge, second went under the first.
