Arc Rider

Turn a tape measure into a big compass

Slide the clip onto a tape measure blade and push a pencil through the side ring: hook the tape over a nail at the centre point, lock it at the radius you want and swing it, and the pencil draws circles and arcs as large as the tape is long, for arches, round tables and garden beds.
