If you're in the market for a table saw, you'll have a number of options and features to consider. To make the best decision, a basic understanding of the "inner workings" of this woodshop standard is essential. Below, I'll describe the primary table saw components, what makes them important, and what to look for when it comes time to buy.
A table saw is the most common piece of large woodworking equipment found in shops around the world. Table saw are very versatile, and if you can only have one piece of woodworking equipment, a rigid table saw is probably the best one to choose. These more portable types of table saws offer versatility and ease of use with the convenience of portability.
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.
Motor horsepower and blade size are closely related. The larger the blade, the more horsepower you will need to cut, at full blade height, through a piece of wood. Too much power is never a problem. Too little power can cause the saw to bind, slow down and even stop in the middle of a cut. This is not good, nor is it safe.
Saws specifically designed for hobbyists and home use are usually outfitted with motors under 3 HP and can be operated on standard 110 volt residential circuitry. In general, motors in this class are powerful enough for routine cutting of sheet goods and hardwoods up to 1'' thick. Professional-class saws, on the other hand, have motors in the 3- 5 HP range and require a 220 volt power supply. Motors in this category are designed to stand up to hours of continuous duty, and have enough power to cut thick, heavy hardwood stock without bogging down.
