Careful layout is crucial to a woodworking project. Measure or mark a part inaccurately and it almost certainly will cause problems. With that in mind, Chris Gochnour gives the lowdown on his 11 favorite measuring and marking tools. These are the tools he keeps within easy reach and uses almost every day: 12-in. combination square, framing square, 4-in. engineer's square, 12-foot tape measure, 6-in. straight rule, marking knife, pencils, dial caliper, marking gauge, bevel gauge, and scratch awl. As important as any hand or powered cutting tool, these tools are essential for a well-equipped workshop.
