A variety of measuring devices are provided for determining a radius of a work piece having a substantially circular cross-section without contacting opposing sides of the work piece. A guide portion includes a first side (105) and a second side (105) which contact two points of the work piece (120). A probe (110) measures a distance to the work piece. In some embodiments, the first and second sides (105) of the guide portion form a Vee and the probe (110) is disposed in the vertex of the Vee. In some embodiments, the first side (105) of the guide portion may be moved relative to the second side (105) in order to accommodate a wide range of work piece sizes. |
