Hes trying to leave the waste on the stump so he doesn't have to clean the butt and maybe got a little lazy with it. Besides, some mills don't mind a little snipe. The wide open face and boring from both sides is indicitive of GOL cutting stlye. I've seen where guys scratch a nearly 90 degree piece out and call it a 'notch'. The problem with this cutting style is that it assumes too much and doesn't teach the mechanics of control. This is pretty typical in hardwood logging. I don't cut that way, but a good portion does.So since he cut to keep the flare on the stump( maybe) then would he not have to clean up the butt? If so then it was pointless and he could have left a step for saftey and not flat with holding wood.
Why such an exaggerated undercut? the opening is huge, way over a one to one ratio, 1-1 would be something you would do on a Swanson or Pie/birds mouth.
1/2 to 1 would give you a 3" opening at 45% with a 6" depth. This guys just under 70% I'd bet. But yet he's about cutting in the duff. Not making a lot of sense to me?
