Joe and Elisabeth,
I thought I might get some bites on that statememt...
Humboldt in my experience is used by fallers, either that have been trained in loggging operations or trained by a logger. So they use the homboldt because they have been trained that way. What other reason is there?
Make your argument.. I have made mine... Oh and BTW it's not really mine... It's Tim Ard's and other pro teachers...
Why cut the humboldt... it's harder to make... easier to make a mistake on.. harder to get the gun perfect etc...
I think this is a good teaching piece for everyone here. Just becasue a technique is right in the woods, doesn't make it right in the backyard... This is a very important concept for the suburban arborist to understand... Blindly following the lead of loggers is a MISTAKE!
I have gone back and forth between tree service and logging my whole life. I know of very few people who have been able to easily move back and forth between the two.
The main reasons are pride and prejudice. Fallers and climbers are by nature some of the hardest headed and self confident people in the world. This easily turns into arrogance and the inability to learn from any other source. Also we tend to get bombarded with alternatives that are not efficient, effective, or safe for the circumstances that apply to us, so we start to get narrow minded and hit a plateau that we will never move above.
When I first started cutting conventional face cuts, I had a hard time lining them up and making them pretty. But with practice and perseverance, they soon came to be fairly easy. The same with humbolt face cuts. It was unnatural at first but now they are just like second nature.
The proper gunning cut of either is identical, so I can not see how the conventional is easier to gun.
Tim Ard is no faller, he is awkward, inefficient and often unsafe in his methods. For me, he will remain a fine example of how not to cut.
On bigger trees the humbolt is much more energy efficient and easier to tell when your under cut gets to your gun cut.
In all reality there is very little difference in the two styles in the way they influence control over the falling tree. So little that it is almost a none issue in residential tree work.
What I see as a real issue with face cuts in residential tree work and line clearance tree workers, is the great increase of unintentional dutchmen, stray kerfs, and general lack of understanding of the basic felling cuts.
A lot of these guys are getting some really poor training, but are completely set in their ways.
