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.
The smallest motor I would even consider for a 10-inch saw would be 3 horsepower. For a 12" to 14" saw it would be 5HP and for a 14" to 16" saw, I'd like 7.5 HP. You will also need to consider if the saw motor is single or three phase. Three phase motors use electricity a bit more efficiently. If you don't have three phase power at your location, however, you will either have to buy single phase or purchase and install a phase converter large enough for your saw motor. Most saw motors use 230 or 460 VAC power, so make sure you have available in your shop the voltage your saw will require. Three phase motors can run on 208 to 220 volts or higher, depending on the motor.
At least one, but preferably two or more access doors should be provided leading into the cabinet of the table saw. The one you will use most often will be for cleaning out the interior of sawdust. Another should give easy access to the motor, trunnion and belts for adjustment and repair. Many saws provide a removable access panel instead of a second door. That's fine for occasional motor, arbor, belt and trunnion access but you will want the sawdust door to open and close easily.
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.
Most table saws use the miter gauge and miter slot system to allow for crosscutting. A miter gauge consists of a cast metal protractor head attached to a length of metal bar. The bar rides in corresponding "miter slot" in the table saw's surface. Protractor on the "no frills" miter gauges that come with most table saws can be set to crosscut stock at any angle between 90 and 30 degrees and, if well made, do a serviceable job with most "routine" crosscutting.
