On certain projects, you may be required to work with brass screws. While the brass results in an attractive finished project, it is a soft metal that can easily be scratched or damaged. The solution is to use your drill to create a pilot hole, then drive a regular steel screw of identical size into the hole. After the hold is created, remove the steel screw and replace it with the brass one.
Make sure you wear proper safety gear and make three simple cuts. Make your first cut at a slight angle, no more than two-thirds into the tree. Make a second cut to form a wedge. Then make a final cut on the opposite side, cutting into the wedge from above. Cut carefully, watch for the wind, and the tree will fall safely away from you.
