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.
The ideal solution is to have enough shop space so that you will never have to move your saw around at all. In this situation, you can construct an outfeed table to support large work pieces and long lumber as they leave the back edge of the table saw table. Ideally, depending on space available, you should build this outfeed table so that it extends eight feet or more in back of the blade. You can use the space underneath the table for lumber storage and/or drawer space. The table can also serve as a work bench for the construction of large cabinets and tables. You can use it for pipe clamp glue-ups and spray painting layout, as well.
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.
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.
Some shops are small enough to require that all machines be able to roll around on the floor. The theory is that you pull out only the machine you are using at the time. In planning your shop, you should decide if your space requirements will mean that everything has to roll, some machines but not others have to roll or all machines can remain in their own positions permanently. Many cabinet saws offer the optional extra of some sort of mobility device. In the case of a table saw, you don't want it rolling around while you are pushing lumber through it and so the wheels must retract enabling the saw to rest on its cabinet base on the floor.
