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.
Here's the best way to remove finish nails from old woodwork. After carefully removing the woodwork from the wall, pull out the nails using a vise grip. Grasp the nail with the vice grip on the unfinished side of the wood and pull the nail through. Repeat this procedure until all the nails are removed. This method keeps the finished face of your woodwork intact.
Carpenters who do rough construction get very proficient at "close-enough" measuring. For example, to quickly draw a line parallel to the edge of a board, you can place a pencil at the end of a combination square and move both the square and pencil along the board. Some combination squares have a hole in the blade for this purpose.
