ABSTRACT:
A compass for sweeping an arc of a circle on a sheet of material comprises an annular base having a lower surface engageable with the material. A support member is rotatably supported on the base and a toolholder is mounted on the support member. The toolholder is moveable with the support and upon rotation of the support relative to the base, sweeps an arc of a circle. The toolholder has a toolpost to support a tool and permit movement of the tool relative to the support member in a direction generally normal to the sheet of material to facilitate movement of a tool mounted in the holder into and out of engagement with the sheet of material.
