The blade in a table saw is exposed so if you are not careful, you can easily hurt yourself. You can adjust the depth of the cut by exposing more or less of the blade. The more the blade protrudes, the deeper you can cut. Modern table saws come with a number of safety features to reduce the danger, like dust extractors and magnetic feather boards. Reducing the blade height is also a good way to reduce the chances of grievous injury.
Although the term “woodworker” may evoke the image of a craftsman who uses handtools to build ornate furniture, the modern woodworking trade is highly technical and relies on advanced equipment and highly skilled operators. Workers use automated machinery, such as computerized numerical control (CNC) machines, to do much of the work with great accuracy.
Sometimes called “Panel Saws”, these hand saws have a handle and thin flexible metal saw plate with no rigid back or frame. Hand saws have larger teeth and are generally used for quickly rough-cutting boards to length or width. These hand saws were manufactured in very large quantities and are easy to find and usually inexpensive. The specific name of this saw type also happens to be the general name of all non-power saws: “hand saw”.
There are two types of electric circular saws, the worm drive and the sidewinder. The worm drive saw has enough torque to cut through wet lumber and concrete. The behind-the-blade handle placement reduces kickback, and the blade’s left-side position makes it easy to see your cut line if you’re right-handed. The sidewinder’s motor, attached directly to the blade, weighs less but also has less torque.
