If you consider that a sheet of plywood measures 48" in width, I would think that you might want to opt for a 50-inch rip as opposed to the slightly less expensive 30" rip capacity. You might want to rip off only one inch from that sheet of plywood and, while doing that, you will want the plywood to be fully supported. You might want to crosscut a sheet of plywood into two 48" pieces. You also should consider the rip space to the left of the blade: The wider, the better. Sometimes, you might want to accomplish tasks that require the fence to be put over to the left side of the blade.
Saws specifically designed for hobbyists and home use are usually outfitted with motors under 3 HP and can be operated on standard 110 volt residential circuitry. In general, motors in this class are powerful enough for routine cutting of sheet goods and hardwoods up to 1'' thick. Professional-class saws, on the other hand, have motors in the 3- 5 HP range and require a 220 volt power supply. Motors in this category are designed to stand up to hours of continuous duty, and have enough power to cut thick, heavy hardwood stock without bogging down.
There are four main classes of table saws: contractor saws, benchtop table saws, cabinet saws and hybrid saws. When deciding between portable and floor standing table saws, the main thing you're trying to do is balance durability with portability. Since most portable types of equipment do not have the same durability features, they typically do not last as long as their less portable counterparts.
In older table saw, altering the angle of the blade was used to increase or decrease the depth of the cut. Nowadays, there is still an adjustable angle control, but this is used merely to adjust the angle at which the material is cut, and is not used to decrease or increase the depth of cut being made.
One drawback of lighter-weight table extensions is that they have less mass, and the overall mass of the saw is what soaks up the vibration crated by the motor and other moving parts. The added mass of heavy cast iron extension wings decreases vibration, which in turn helps the saw stay in calibration, and also helps it stay planted firmly on the shop floor. On less expensive saws, extensions made of stamped metal, or ones that aren't precision ground, can also compromise the overall flatness of the table surface.
