Well I'm back.
After another long day of setting facecuts in big beech trees
Jed as to your question about how we maintain levelness of the face when we put the top cut in first.
Practise makes perfect.
That is really all there is to it. Do it enough times and it'll become second nature.
Which is why if I changed my modus operandi and did the horizontal cut first, I know I'd be back to square one and have to relearn it all again.
I took down a large doug fir last summer and decided that the only way to avoid breaking it over a swale in the ground was to use a humboldt with a snipe. So I made my first Humboldt. Worked fine, but that humboldt looked like something made by a beaver OD'ing on crack.
I posted a picture here to general amusement.
But with any method, if you do it enough times and are conscious of what you are doing , you'll eventually master it.
The main thing is to be aware of what you are doing and NEVER getting sloppy.
Back in my pulp cutting days there were two kind of fallers. Those who would just get the trees down any old way in a clearcut ( they are bucked to short lengths anyway, so it doesn't matter if you cross them and break some) and those , like myself, who'd make a game out of picking an exact target for each tree to hit, even though it didn't really matter.
I don't have to tell you which group made the good money in thinnings, where there is hardly any room to fall into, and each hung up tree looses you money, do I
