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.
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.
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 rip fence guides the wood as it is being ripped (cut along its length) and can be positioned to any width of cut within the saw's range. The fence rides on fence rails attached to the front and rear edge of the table. Ideally, the system keeps the fence perfectly parallel to the plane of the blade, regardless of where the fence is positioned.
Motor horsepower and blade size are closely related. The larger the blade, the more horsepower you will need to cut, at full blade height, through a piece of wood. Too much power is never a problem. Too little power can cause the saw to bind, slow down and even stop in the middle of a cut. This is not good, nor is it safe.
