Snap a sharp line in glass
Having four daughters and three grandchildren, I am forever making picture frames. Usually these frames are not a common size, so I started to cut my own glass with mixed results. Finally, I made the glass-breaking jig shown right to provide uniform pressure for a clean break. On one of the plywood layers, I glued a 1⁄16 ×1" scrap of plastic countertop laminate.
To use the jig, clamp it over the glass sheet, leaving just enough room for the glass cutter. After scoring, reclamp it next to the score line, and snap off the extra glass.
