When I build woodworking projects with curves, I often turn to my trusty homemade curve tracer. It's made from a long, 1/4-in.-thick strip of straight-grained, knot-free wood with a 1/4-in. hole drilled in one end and a narrow V-notch cut into the other end. I tie mason's string to the drilled end and bend the strip to whatever size curve I need, tying a knot in the string that I slide into the V-notch. Then I just hold the bowed wood on top of my workpiece and trace the curve. Leave it unstrung between projects or it'll become permanently bowed. — reader Bruce Philbrook
