Some saws shield the blade in a casing underneath the saw table and suck the dust out directly from there. Others slant the floor of the saw cabinet towards a dust collection port. Many just allow the sawdust to accumulate on the floor under the saw until you clean it out. You will always have some cleaning of the interior to do. Perhaps you won't wait until the sawdust has totally encased the trunnion gears packing itself up to the bottom of the table top. You will need to connect the saw to a dust collector through its dust port. The suction of the dust collector should be about 350 CFM for a 10" saw and more for a larger saw.
Your new saw must have a rip capacity equal or wider than the widest thing you will ever want to rip. Usually, a cabinet saw will have a rip capacity of around 30 inches or 50 inches. A large rip capacity to the right of the blade will require an extension table to support work wider than the cast iron table. Many times, this extension table is included with the saw or, alternatively, you can easily build you own. The fence must have a tube or rail long enough to achieve the maximum with you want to rip.
The table saw is the heart of your shop. You will use it more than any other machine and its accuracy and capacity will determine the quality and size of what you will be able to produce. This is akin to picking someone to marry: Ideally, it's for life and you will have to live with your decision for a long time to come. Therefore, rushing into purchasing the first table saw you see, without doing your homework, is like a quickie Las Vegas marriage, always a gamble.
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.
Also known as the open-stand saw, the contractor saw is heavier and more durable than the bench top saw. Its circular saw is mounted on a heavy table with an open set of legs. This type of saw is usually preferred for those who have a tool shed at home since it is moderately-priced and does not require any extra voltage than is provided in a regular outlet. While this model is heavier and less portable than the bench top model, the contractor table saw is still usually moved from job to job (most contractor saws come with wheel attachments to make this easier).
