The trunnion is the mechanism inside the cabinet which is responsible for both raising and lowering the blade and tilting the blade for bevel cuts. It is controlled from the outside of the saw by two separate wheels or cranks: one for raising and lowering the blade (usually found on the front of the cabinet) and the other for tilting the blade (either left or right, depending on the saw) which is usually, but not always, located on the side of the cabinet.
The fence must be aligned so that the front of the blade and the rear of the blade are exactly the same distance from the fence at all settings. Once you have ascertained that the blade and fence are parallel to each other, you must cut some test boards to accurately set the fence to the scale. Set the fence to exactly 2" on the measuring scale. Rip a test board and measure it. Adjust the fence to the scale by moving the viewer's hairline left or right. Rip more boards until you have exact accuracy. The viewer through which you see the tape should be strong in magnification.
The quality of the table saw surface (or "bed") is extremely important to the overall performance of the machine. The table surface needs to be reliably flat and rigid to properly support the workpiece during a cut. As one of the most massive parts of the saw, the table surface also plays a major role in absorbing vibration. Because of the need for mass, rigidity and flatness, cast iron is the material of choice for the top of a table saw. On a quality saw, the table is made using a hefty quantity of cast iron and state-of-the-art foundry methods. The end result of the casting process is then precision ground to flatness in the .0005'' tolerance range.
The cabinet saw, contractor saw, hybrid saw, and bench top saw are all types of table saws that will help you in your woodworking projects. Each saw is slightly different to accommodate the certain needs of the woodworker. One must find what they need out of there table saw before determining what type of model they need. However, for the average woodworking projects, you cannot go wrong with a quality contractor saw.
A hybrid table saw is a lot like the contractor saw with a few key differences. For one thing, it is much more compact than the contractor saw and does not require as much room in your tool shed. The hybrid table saw also offers some of the features of the cabinet saw. With its solid and heavy base, it has the lower vibration of a cabinet saw along with dust control. A contractor saw or a hybrid saw of good quality suits the needs of most woodworkers.
