ABSTRACT:
A jig in the form of two fairly rigid plates, with clips, of magnetically attractable material positioned next to each other with two of their side front edges adjacent and the rear portions of said sides cut away. The forward part of said adjacent edges are optionally bent slightly upwards. The bottom of each plate, towards the front, is attached to an extension piece by a hinge and the bottom of said extension piece contains a strip extending longitudinally behind the plates with a magnet at each end spaced so that they magneticallly attract, without contacting, the plates when the clips hold a sheet of glass and the plates are about horizontally extended. The extension piece is provided with a front section on which an elongated bar is adjustably attached, said bar having a slot to guide a glass cutting tool and extending forward over said adjacent edges of the plates. The extension piece contains resilient material under the adjacent edges, bearing up against said edges when the plates hold the sheet of glass and are horizontallly extended.
