Most homeowners need to be guided on how to cut down a tree.
Cut a notch using the ˝open face ˛ or ˝undercut ˛ method as described in the OSHA Logging Standard 29 cfr (g) (2) (iii), making the se- lection based on tree species, size, lean, location, and safety. In order to cut a notch in a tree with a crosscut saw and an axe, the first cut is sawn perpendicular to the grain of the tree with the crosscut saw. Next, an axe chips the wood out using downward angled strikes; it is interesting to observe that an axe chips out wood best at a degree angle to the wood grain.
It is reasonable to deduce that the degree common notch is a result of the limitations of the tools available at the time. Many cut the same notch. Nov 27, The concept of directional felling is based on creating a “hinge” of wood that guides the tree during the fall. The hinge is formed by the directional notch and the final felling cut.
The Makita UCA is a inch corded electric saw that offers heavy-duty performance with a chain speed of 2, FPM for fast cutting operation.
The placement, angle and depth of the directional notch are critical to ensuring the desired direction of the fall. If you are new to directional felling or simply want to refresh your skills, we recommend that you take a look at Understanding directional shrubcleanup.barted Reading Time: 6 mins.
Mar 25, Felling the Tree The back cut that you make, which will fell the tree, needs to be done towards the direction of your notch. A good guideline to ensure an accurate cut is to circle the tree starting from above your notch using a slow-running chainsaw to create a mark. A simple way to avoid hinge failure and loss of control when falling trees is to cut a notch opening that allows the hinge to stay working and in control until the tree is on the ground.
This requires a notch opening of 70 to 90 degrees. This can be easily cut with the modern day STIHL chain saw.
I do not ask you to take my word for it.
