Benefiting from greater experience
Bill Tindall, E.Tn.
the person I cut for hated butt splinters on saw logs. He advocated powering the saw into the tree until it hit the ground (well almost). Then I took a class and learned that leaving a robust hinge was judged safer by a body of experience many orders of magnitude greater than mine/ours. And then I recalled two dangerous tree falls that would have been rendered uneventful by leaving a wedge. I "got religion" on tree felling.
Reminds me of electrical codes. Some seem unnecessary but then one has to consider that the code came from a body of experience that showed otherwise.
the events- cut tall above canopy poplar on extreme steep bank. Butt sawed loose and it floated above ground as it fell supported by its umbrella-like top. Butt eventually hit ground and fortunately it carried forward.
huge tall exposed beech sawed through and a puff of wind stood it back up on its stump. There it teetered for more than a minute before another puff blew it over in an unpredictable direction(I had long since abandoned the saw and left the scene). Pressure from tree embossed logo on bar into the butt surface.
