One table saw manufacturer I know believes in "aging" its cast iron machine table tops before milling them flat. The tops are cast and then left outside in a "bone yard" to bend, bow, warp and twist in the sun and rain for a year or so. Then, they are brought inside where all the rust is removed and the table top is ground absolutely flat and polished to sheen. The theory is that the metal needs to settle into a place where all post-casting movement has ceased and that the table should not be ground flat before this is done. Otherwise, the table may move out of absolute flatness after it is part of your new table saw and that it not at all desirable. Why? Because the flatness of your table saw top will determine the accuracy of your cuts. Be sure to check your new table saw for table flatness with a straightedge on or before delivery and afterwards from time to time. Lay the rule across the table top at all angles and check for daylight under the rule or rocking of the straightedge on the table top.
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.
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.
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.
Most table saw trunnions are made to tilt either left or right (but not both) to a maximum of 45 degrees from vertical. If you have a choice, and you usually do, never buy a right-tilt saw for the following reason. A right-tilt saw tilts the blade towards the fence and can pinch a work piece into the fence, causing a jam or, worse, a kickback just as the cut is finishing. Further, on a right-tilt saw, the blade is tilting towards the fence and could cut into and ruin it if the fence were to be inadvertently moved too close to the spinning blade. A left-tilt saw tilts away from the fence and instead of pinching the work piece, allows it to rise vertically slightly, if need be.
