The size of the cast iron table saw top is also important: the larger the better. When you are sawing large objects, you want as much flat table surface as you need to support the work piece flat to the blade for accuracy. Larger table size is usually accomplished by attaching cast-iron table wings to the edge of the main table. These wings must be as flat as the table and the seam they create must be aligned so that the top of the wing is flush to the table saw table along its entire length.
In the modern table saw, regardless of type, the depth of a cut is changed by adjusting the distance that the blade sticks out above the table surface. The more the blade protrudes from the table, the deeper the cut that is made in the material will be. Conversely, the less a blade protrudes from the table, the more shallow the cut that is made in the material being cut, will be.
The quality and accuracy of fence systems, however, varies greatly across the spectrum. The quality of a table saw's fence system is an extremely important consideration: A poorly designed or inaccurate fence greatly diminishes the quality and accuracy of the cut, and can be a source of significant frustration. For saws in the price range of most hobbyists, the famous Biesemeyer T-square fence design sets the standard. Fortunately, many smaller, more affordable saws come standard with a reasonably accurate system patterned after the tried and true Biesemeyer design.
One drawback of lighter-weight table extensions is that they have less mass, and the overall mass of the saw is what soaks up the vibration crated by the motor and other moving parts. The added mass of heavy cast iron extension wings decreases vibration, which in turn helps the saw stay in calibration, and also helps it stay planted firmly on the shop floor. On less expensive saws, extensions made of stamped metal, or ones that aren't precision ground, can also compromise the overall flatness of the table surface.
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.
