The table saw is the most versatile option for the DIYster, equally successful at making rip cuts (with the grain) and crosscuts (across the grain). When making crosscuts, it's much better to rely on support which holds the workpiece at a 90-degree angle to the blade, rather than the rip fence, which is parrallel to the blade.
Enter the crosscut sled, an extremely easy homemade option for safe and accurate crosscuts on any table saw. This option uses materials that you probably have on hand, but can easily be purchased for under $5.00.
