making butt cuts

When making a butt cut — or any joinery cut for that matter — the first step is to check the alignment of the tool. The saw blade must be perpendicular to the saw table. (See Figures 3-1 and 3-2.) In addition, when making a cross cut (on a table saw), the miter gauge must be perpendicular to the saw blade. For a rip cut, the fence or guide must be parallel to the blade. Use squares, drafting triangles, or rules to check these alignments.

After checking the alignments, position a board on the saw. With the saw turned off, advance the board until it touches the blade. Check that the layout lines on the board are properly aligned with the blade teeth. In some cases, you may have to transfer the layout lines from one surface to another. It also helps to clearly mark the waste side of a layout line — the side on which you want to cut the kerf.

3-1 To accurately align the parts of a saw, you must compensate for "run-out" — the slight wobble that afflicts all saw blades. Using a rule, carefully measure the distance from the teeth on a saw blade to the miter gauge slot. As you rotate the saw blade, you'll find this distance isn't constant. Identify the "near" and the "far" teeth on the blade. Using a marker, draw a dotted line between these teeth, then a solid line perpendicular to the first. Both lines should pass through the center of the blade.

3-2 When checking the saw alignments, lay the square or triangle against the solid line on the blade. Or, measure from the teeth at either end of this line. These points will provide more accurate references than any others on the blade.

When crosscutting on a table saw, it's sometimes difficult to position the board. Often, the surface with the layout line faces away from you, and to align this mark with the saw teeth, you must lean over the blade. A better method is to make and use a "third eye." Purchase an inspection mirror at an automotive store, cut off the handle, and mount the mirror on a small wooden base as shown. When you need to see something that faces away from you, place your third eye where tt will reflect what you need to see.

To make a cut, feed the wood into the blade slowly, using a steady, even pressure. Monitor the blade constantly, and slow down if it begins to bog down or vibrate. If the blade binds or burns in the cut, you could have a piece of reaction wood. Discard that board and get another. Vibration, bogging down, binding, and burning can also be caused by improper alignment. Check the tool setup carefully.

If you have to make duplicate cuts, feed each board at the same rate and with the same pressure. Remember that a saw, like any mechanical system, must have some "play." Although a miter gauge may seem snug
