There are many things you will want to consider before purchasing a new table saw for your shop. There are three main types of table saws: (1) the lightweight, inexpensive and portable contractor's saw, (2) the cabinet saw, so-named because it has an enclosed cabinet as opposed to open base and (3) the new breed of so-called "Hybrid" table saws which fill the price gap between contractor's saws and cabinet saws. This discussion will be only concern cabinet saws because, in my experience, nothing less will do for a shop that produces fine woodworking. Smaller saws lack both the accuracy and capacity of cabinet saws.
According to different table saw reviews,this first type of table saw is the handiest type among the four types of saw because it can be carried out by a person from one job to another job. This is true for the reason that it is made up of aluminum and steel as well as plastic making it compressed and light in weight. This factor allows it to be positioned on the upper part of a table or other provision for maneuver. This type is also the least expensive among the types making it appealing for customers who are looking for a portable table saw that suits their budget. This is indeed a thrift choice but you have to keep in mind that you will just get what you have paid. Since this type is limited in size and dimension, its capability and durability is also limited. It is also subject to upsurge vibration when cutting. This means that this type of table saw is restricted only for light workloads.
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 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.
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.
