i think in terms of the front /back leveraged extremes of the narrow part of hinge ushering the tree shape to target;
BUT, then Left/Right leveraged extremes on long part of hinge steering the CoG to same target.
>>CoG forcepoint can over-rule narrow part of hinge steering shape
>>Whole secret is to remove what isn't needed, while preserving /not cutting the most needed leveraged positions
.
Center Punch takes out fibers that can't steer; allowing re-apportioning of same fibers (so has the same fold forward resistance)
>>to the left/right steering extremes for increased steering control.
>>Similar to Tapered Hinge re-apportion fibers to have same fold forward resistance; but more sideLean resistance.
.
i remember having to paint cuts with that messy tar crap; that got all over like pine sap does.
It was what the new guys did to prove climbing and positioning before being allowed to carry more than hand saw;
>>by following climber on some stuff and painting their cuts as a break from dragging logs.
The positioning can be more extreme to paint rather than cut it seemed;
Far cuts were made with paint brush in the metal loop forged on end of polesaw under blade, held by spring clip
>>sometimes had to remove blade,slide in handsaw holster so wouldn't interfere with painting.
