How To: Use a Miter Box
A miter box is a wonderfully simple, affordable tool that allows any DIYer to make accurate crosscuts in wood. Since these tools are hand-powered, they are quiet, and they’re light enough to be easily moved to any project location. An added benefit, the miter box minimizes and neatly contains sawdust, making it a viable sawing solution for those living in small apartments.
What Is a Miter Box?
A miter box consists of two components: a hand saw whose teeth are set for crosscutting (cutting against the grain of the wood) and a “box” that is pre-fashioned with slots on both sides to help the woodworker make accurate angled cuts (typically 90° and 45°). A miter joint, the tool’s namesake, is made by fitting together two 45° cuts to form a right-angled corner.
A miter box is a go-to for anyone less inclined to work with power tools, whether on account of space restrictions, safety concerns, or cost. You can buy a miter box for a fraction of what it costs to purchase its powered big brother, the benchtop compound miter saw. And comparatively, the miter box is much easier and safer to operate.
Types of Miter Boxes
Historically, a carpenter or woodworker would create his own wood miter box to use in combination with his favorite saw. Today, miter boxes can be purchased in three basic designs.
The molded plastic variety is readily available in hardware stores and home centers. Basic models can be had for as little as $12 or $15, with more advanced options maxing out around $25. These affordable tools can make quick work of simple, light-duty tasks, such as creating basic picture frames.
The next level up, precision miter saws feature a higher-quality saw, a fuller spectrum of degree-cutting (with stops for common angles), and hold-down clamps to keep the work in place. Rather than plastic, precision miter saws are made from machined metal for added strength and stability. This is the best option if you’re planning to install molding or trim, or if you cut the occasional length of dimensional lumber.
A great hobby shop addition, the fine woodworking miter saw is used for wood stock that would be damaged by the rotating blade of a power tool, or any saw with coarser teeth. Due to its limited size, this type of miter box works best with light and small trim or decorative pieces.
Using a Miter Box
Begin by clamping your miter box to a stable surface with a bar or quick-release clamp. Alternatively, secure the box via nut and bolt. Next:
1. Measure your cut length accurately and use a carpenter’s square or triangle to mark the cut on your wood stock, being sure to measure to the long end of any 45° miters.
2. Place your wood or trim in the miter box, using any clamps or hold-downs to secure the piece to the box. Make sure to correctly orient the wood toward the angle of cut, noting whether you want the cut across the face of the wood (a bevel) or across the height of the wood (a miter).
3. Using light passes, score your cut line just to the outside of your pencil mark, then increase your effort to cut through the work piece.
