The Fence. One crucial component of every table saw along with the engine and blade is the fence. In fact, making a precise rip cut would be impossible without it. There is basically one type of fence most table saw manufacturers tend to use, but before we get into that let's go over the main characteristics a good fence should have. First of all the fence should allow for easy and hassle-free adjustment both horizontally and vertically. The fence should also sit on the rails firmly, and there should be NO “wiggle” room apart from the sliding.
When you are making angled cuts simply align the sheet with the straight part of the miter gouge, and push it together with the miter gouge toward the blade. The saw will make the cut at an angle using the pivoting part of the miter gouge. Whereas fences allow you to make rip cuts, miter gouges provide you with a lot more options. You can make both square and angled cross-cuts as well as specialty cuts. In order to make a cross-cut, you need to slide the miter gouge back toward you. You then need to put the board against the straight part of the gouge.
Essential Information on Table Saw Blades. On this website, I repeatedly maintain how useful table saws are and how much work you can get done if you learn to use them properly. At this point, we're going to assume you've done your homework and decided on a particular type of table saw, or maybe even a particular model, but your work is not quite done yet. Depending on your projects, sooner or later you are going to have to change the blade from the original one that comes with the table saw when you buy it. The choice of the right blade is crucial, and you will need to consider the type of material you will be cutting as well as its thickness.
After you have penciled in a line where you want the cross-cut to be made, align it with the blade. With the saw turned on guide the miter gouge forward until the cut is made while making sure the board is firmly in place against the straight edge of the miter gouge. One of the simplest cuts a miter gouge allows you to make is a square cross-cut. Simply set the miter gouge at 90 degrees or zero (depending on the markings), and push the board toward the blade. The result will be a board that is cut square. You can also make angled cuts by setting the miter gouge at an angle of up to 45 degrees.
I would also recommend you to look for switches that have a “sunk” or plastic cover which prevent you from turning the saw on accidentally. If you have kids running around the shop, consider a saw that comes with the ability to add a padlock. Actually, this comes in useful even if you don't have kids who are likely to gain access to your workshop.
Obviously, the easiest way to know which blade fits your table saw would be to consult the instruction manual. Also, use some common sense. There is a finite amount of space inside the arbor, so you can't use just any blade. The space is also limited with the presence of a blade guard. Speaking of the arbor, the central arbor hole on most table saw blades is 5/8 inches in diameter, but then again, there are exceptions to that rule. If the diameter and the arbor are supported by the saw, you are on the right track.
Splitter and Anti Kickback PawlsOne of the leading causes of table saw related accidents is kickback, which occurs when a piece of wood gets ejected at high speed, back toward the operator. This can cause some serious injuries. This happens when the wood binds between the fence and the blade, and then gets caught by the teeth on the back on the blade. In order to prevent that from happening, many table saws are fitted with a splitter. A splitter is basically a small vertical blade made of metal or plastic, which holds the Cerf open behind the table saw blade. It's a simple solution that works, up to a certain point.
