Chainsaw Terminology

[jimmysisson]

different dutchman

WOT=wide open throttle Dutchman=undercut in which the two cuts do not meet and the flat cut goes past the other one into the holding wood, can cause the tree to barberchair. Domino=pushing over a cut-up tree or trees with another tree.

In carpentry, a dutchman is a piece of wood fitted into a divot or somewhere there's damage to surrounding wood. Kind of like the storied Dutch kid's finger in the dike, fits tight. Wonder where dutchman in felling comes from.

Here we use wedges to prevent setback, and use the borecut for headleaners. It allows you to get you back cut up to the holding wood, and then nip the holding wood at the back of the tree to prevent the barberchair, or a split piece of merchantable timber.

The problem with a barber chair is that the spar, or whatever you want to call the tree above the stump, can peel off the cambium and kick straight back. Which is why you stay off to either side of the stump as best you can.

Of course, the tree can break off the stump/spar when the top hits the ground and come down on either side of the stump ... hopefully not the side you picked.

A couple of months ago, I heard about an old guy got killed by a 20" tree that barberchaired up 16' and then came down him. He couldn't get out of the way, fell down or something........Thats a lot of tree to land on top of ya.....

Well true. Anything can happen. That's why you get out of the way. But you're safer on either side of the tree than directly behind it.
