Summary:
This video talks about 6 common mistakes people make when using a table saw.
Not knowing the difference between the workpiece and the cutoff piece: It's important to know which piece needs support. Usually, you want to provide support for the workpiece. When using a miter gauge, an exception is when using a stop block on your RIP fence to make repeated cuts on small pieces.
Not supporting the workpiece correctly when using a RIP fence to cut a wide board: The workpiece should be on the side between the blade and the fence. Don't guide the sheet from the cut off side.
Using only one push stick: You need two push sticks, one to push the lumber forward and the other to keep the wood pressed downward and against the fence.
Not using a push block: A push block is a great way to ensure an accurate cut. You can make one yourself with a scrap of plywood.
Cranking down the nut on the arbor too tight: When you're installing a blade, just crank down the nut until it stops. You don't need to overtighten it.
Not supporting the long side of the board: The basic rule is to support the long side of the board, not the short side. If the board seems to want to wobble, use your miter gauge instead.
