The radius ruler: to measure the radius of a curve
Nothing comparable to this brand new invention has ever existed before. The Radius Ruler is made from sturdy 15 pt. paper, and it can be used to measure a curve as small as 60 degrees with a radius up to 3.5". It's a new fundamental innovation, not an improvement of anything that already existed, so it's many known applications are new solutions to old problems, and new applications are turning up everyday. Replace the hit & miss guess work the wood worker often faces with a quick measurement to determine what size router he needs to match another curve, or to quickly tell if a piece has been turned enough. Quickly measure a pipe size without needing access to it's opposing sides. It won't be long before measuring the radius will be as common as measuring a length or angle, as we come to recognize that applications abound in the world around us.
