Abstract
A guide plate assembly, mountable on the table of a saw which guides a sheet rotatably fixed to the guide plate to enable the saw blade to cut the sheet into a circular disk of a desired diameter. The assembly includes a first slide bar that may be latched in position in a miter slot of the saw table, with a plate attachable to the first slide bar that is slidably latched to the first slide bar, and a second slide bar fitted with one or more cylindrical pivot holes which is also slidably latched in an open slot of the plate. A pivot screw, in the form of a wood screw fitted with a cylindrical head is fastened to the center of a sheet, to be cut, and the cylindrical head rotatably mounted in a pivot hole of the second slide bar, so that the sheet may be circularly rotated about the cutting edge of the saw blade.
Claims2
A guide plate for mounting on the work table of a power saw, said plate fitted with means to center and rotate the work piece with regard to the cutting point of the saw, in which the guide plate is fitted with a first bar of a size to fit in the miter slot of the work table, and fitted with a slidable second bar that is formed with a cylindrical hole, said hole of a diameter to rotatably fasten the cylindrical head section of a screw which is attachable to the work piece,
- said screw formed with a cylindrical shaped head section joined to a tapered pointed section which pointed section is externally formed as a tapered male screw thread, with said pointed section separated from said head section by a projecting radial flange section of a size to extend beyond the circumference of the cylindrical hole of the slidable second bar, when the head section is engaged in said hole, so that the screw may freely rotate in the cylindrical hole of the slidable bar, with the flange supporting said screw in the axial direction of the screw, and so that a work piece threadably engaged in the pointed section may rest on the said radial flange section.
