Like many, I have hundreds of sheets of sandpaper that must be cut to fit my 1/4 sheet sander. Using scissors is a slow option and a paper cutter is only marginally better. About thirty years ago, some magazine posted this simple, but efficient cutter and i have been using it ever since.
All it requires is a scrap piece of sheet stock a few inches wider than (a little more than the width of a hack saw blade) and about the same length as a sanding sheet, a hack saw blade, two screws and a couple washers.
To make it:
1) Lay a full sheet of paper on the sheet stock and trace around it with a felt tip. When positioning the paper, leave enough room on each side to mount the hack saw blade, in step 3).
2) Measure half way down the long dimension and draw a line, which cuts the outline of the long dimension of the sheet in half.
3) Mount the hack saw blade with a flat washer on each side, between it and the sheet stock. The blade teeth should be on the line which dissected the outline.
4) Slide a full sheet under the blade so it lines up with your initial outline. Pull down from a corner so the paper is torn by the blade, producing a sheet exactly half the original length.
5) Turn one of the torn sheets over, measure for half the longest dimension and mark a line across.
6) Slide the marked sheet under the blade, with the line showing and the grit against the sheet material until the line lines with the hack saw teeth. Now draw another outline on the sheet goods around the bottom of this piece.
When done, for all future cuts:
1) Slide a sheet of paper, grit out, under hack saw blade, lining it with the full sheet outline and pull down, at an angle across the blade teeth.
2) Spin the cut sheet ninety degrees and align it with the half sheet outline and pull down again.
