STRAIGHT EDGE CIRCLE TOOL |
摘要 |
The tool is formed of an elongate rigid bar having a pair of straight side edges extending between opposite ends. Indicia are provided adjacent graduations correlating with distances away from center holes located at each end of the bar. A series of marking holes are provided at various distances away from the center holes. Thus, when a pin is provided through one center hole, a marking tool can be placed within a marking hole having a distance corresponding with a radius of a curve to be formed, and the bar can be rotated about the pin in the center hole while the marker is allowed to form a mark in an underlying workpiece. The straight edges of the tool can also be utilized for forming straight edges. |
