Abstract
A circle cutting machine includes a template that is removeably installed in the bottom of a base. On the base bottom surface are a number of segments that define respective grooves for receiving the template. The base has a cross-beam that defines an axis of rotation and that receives a handle. On one end of the handle is a crank. The handle second end holds a cutting arm. A handle spring biases the cutting arm to contact the cross-beam. The handle is slideable in the cross-beam to locate the cutting arm below the plane of the base bottom surface for easy removing of the cutting arm from the handle. An adjuster rigidly locks and resiliently unlocks the cutting arm to the handle. The template has a circular periphery that enters the base grooves, and a tab that is between two segments, when the template is installed.
