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.
The saw blade is mounted on an arbor with an arbor nut and the arbor is turned by the motor usually via pulleys and 1 to 3 V-belts. The arbor is mounted into the trunnion inside two or more arbor bearings. These should be sealed from dust for obvious reasons. The size of the arbor determines the size of the hole in the middle of the saw blade. This is usually 5/8" for a 10" blade and 1" or larger for blades larger than that. The strength and alignment of the arbor and the bearings which support it determine the accuracy and smoothness of the table saw. Vibration and noise should be kept to a minimum and the saw blade should be straight in the table from front to back at all elevations and bevel angles.
I'd like to take a minute to talk about the features that you should be looking for and what these features will mean to you after you unpack and set up your new table saw. These features include: motor horsepower, blade size, trunnion construction, tabletop flatness, tabletop size, arbor size and arbor bearings, sawdust extraction, ease of operation including raising, lowering and tilting the blade, tilt of the blade (left or right), the necessity of a magnetic switch and the importance of its location, ease of access to the interior of the cabinet, accuracy and ease of operation of the fence, the amount of rip space to the right and the left of the blade, safety features and table saw mobility around the shop. In addition to the table saw itself, you may want to construct an outfeed table around the back of the saw, if space permits. We'll talk about that, as well.
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.
A table saw is one of the most popular pieces of machinery used for woodworking. It consists of a circular saw powered by an electric motor that is mounted onto a table. In order to cut, material is pushed through the saw on the top of the table. It is used mostly for large wood projects such as fences, tables, book shelves, etc. When selecting a table saw it is important to know the different types and the pros and cons of each. The following are the four basic types of table saws and what they have to offer.
