If the waste piece does not snap off evenly, the remainder can be cut off with a wide nosed lineman's pliers or slip joint pliers. Grip the glass with the pliers and, with a downward motion, trim off the waste. Raw edges can be smoothed with oilstone dipped in water. It is easily cut with a saber saw and other saws, but leaves a somewhat ragged edge that must be sanded. Use flat head nails to fasten one of these boards to a wood frame, since finishing nails or brads will not hold.
Contact cement is the best adhesive to mount laminate to raw plywood.
Foamcore One of the lightest sheet materials available. Cut with a mat knife or fine saw blade. Before starting work, clean these with turpentine, then shellac seal them. Loose knots should be white glued, put back in place and shellacked. Check the wood for warping, without too many knots or loose ends.
