How to cut more accurate miters and bevels

Before bevel-cutting or mitering project parts, check the accuracy of your blade or miter-gauge setup by cutting a test box or frame to ensure that all four corners come together with no gaps. A miter-gauge extension that reaches past the blade, backs up the cut to prevent chip-out. For identical-length pieces, fasten a stopblock to the extension using double-faced tape. —from the WOOD shop
