Woodworking can be a dangerous business. Always use a push stick or similar device. Fingers are not replaceable. Never try to rip narrow strips next to the fence. Instead, cut them off of the left side of the work piece. In this case, you would stand to the right of the blade. In short, think ahead about the possible complications of what you are about to do, keep your eyes wide open (wearing goggles, of course) and keep your wits about you at all times.
A table saw is one of the most popular pieces of machinery used for woodworking. It consists of a circular saw powered by an electric motor that is mounted onto a table. In order to cut, material is pushed through the saw on the top of the table. It is used mostly for large wood projects such as fences, tables, book shelves, etc. When selecting a table saw it is important to know the different types and the pros and cons of each. The following are the four basic types of table saws and what they have to offer.
Also known as the open-stand saw, the contractor saw is heavier and more durable than the bench top saw. Its circular saw is mounted on a heavy table with an open set of legs. This type of saw is usually preferred for those who have a tool shed at home since it is moderately-priced and does not require any extra voltage than is provided in a regular outlet. While this model is heavier and less portable than the bench top model, the contractor table saw is still usually moved from job to job (most contractor saws come with wheel attachments to make this easier).
The saw blade is mounted on an arbor with an arbor nut and the arbor is turned by the motor usually via pulleys and 1 to 3 V-belts. The arbor is mounted into the trunnion inside two or more arbor bearings. These should be sealed from dust for obvious reasons. The size of the arbor determines the size of the hole in the middle of the saw blade. This is usually 5/8" for a 10" blade and 1" or larger for blades larger than that. The strength and alignment of the arbor and the bearings which support it determine the accuracy and smoothness of the table saw. Vibration and noise should be kept to a minimum and the saw blade should be straight in the table from front to back at all elevations and bevel angles.
Beginning at the bottom, the table saw base houses the working parts of the saw, including the trunnions, the arbor assembly, the sector gears, and sometimes the motor. On some saws, the base is a "cabinet" type, meaning that a fully enclosed base extends all the way to the floor. Other saws have an open base, meaning that the base consists of a metal box that surrounds the internal working parts of the saw on four sides, but not the bottom. Open base saws have legs that extend downward from the bottom of the base to the floor.
