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.
Many table saws can be purchased with optional extension wings. Table extension wings bolt on to the right and left sides of the table and increase the surface area of the saw to help support wide stock and sheet materials. On a heavy duty stationary saw, the extensions are usually cast iron, while on smaller saws, they may be made of lighter stamped steel or the lighter "webbed" style of cast iron.
There are many things you should consider before you should consider before investing your hard-earned dollars in any particular machine. As I have said again and again, any woodworking machine you buy should be just slightly more capable than what you will demand of it now or what you imagine you would likely to demand of it in the future. While price is important, affordability should not be the sole determining factor in your purchasing decision. If you can't afford the saw you need, wait until you can. Don't saddle yourself with a table saw that may drive you crazy every day of your life. Take a few moments to consider what you really need and which machine will best fill the bill for you.
The rip fence guides the wood as it is being ripped (cut along its length) and can be positioned to any width of cut within the saw's range. The fence rides on fence rails attached to the front and rear edge of the table. Ideally, the system keeps the fence perfectly parallel to the plane of the blade, regardless of where the fence is positioned.
Most table saws - other than small bench top models - are equipped with induction type motors in the 1 - 5 HP range. On larger saws, you'll most often find a "totally enclosed, fan cooled" (TEFC) induction motor. A TEFC motor is designed for continuous duty and is sealed against dust and other contaminants - a significant advantage in a woodshop.
