The saw should come with a Biesemeyer or similar type fence included in the purchase price. This type of fence locks and aligns itself to a rectangular tube attached to the front of the saw table when you press down on a handle. Fence accuracy and ease of operation will be important every time you touch your table saw and so a cheap fence is no bargain. The fence will probably read measurements along a stick-on measuring tape on the top of the front fence rail tube. You will need to carefully adjust the fence for accuracy. Instructions of how to do this should come with the set-up instructions for the saw.
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 trunnion determines the accuracy of your cuts so you want to be sure that it is well built and accurately machined. The saw blade must always be exactly where you need it to be. Furthermore, the trunnion must be easy to operate. It should not require Superman to raise or tilt the blade. As time goes on, you may find that it is harder to turn the wheels or cranks that operate the trunnion. This is usually because of sawdust contamination of the gears and/or lack of lubrication. Some better saws have ways of eliminating sawdust from the cabinet into an external dust port before it can get into the gears. Other saws come with self-cleaning gear teeth.
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.
I'd like to take a minute to talk about the features that you should be looking for and what these features will mean to you after you unpack and set up your new table saw. These features include: motor horsepower, blade size, trunnion construction, tabletop flatness, tabletop size, arbor size and arbor bearings, sawdust extraction, ease of operation including raising, lowering and tilting the blade, tilt of the blade (left or right), the necessity of a magnetic switch and the importance of its location, ease of access to the interior of the cabinet, accuracy and ease of operation of the fence, the amount of rip space to the right and the left of the blade, safety features and table saw mobility around the shop. In addition to the table saw itself, you may want to construct an outfeed table around the back of the saw, if space permits. We'll talk about that, as well.
