When the hinged piece is moved back so the table is flat, I can
place the paper against the hinge pin and it will cut the paper in
half across the short side, as shown below.
Shown below is a sheet cut in half, or rather, torn in half, if
you prefer to put it that way.
Now I can fold the hinged piece back up so I can cut the halves
the other way.
The small hinged piece is sized so that it will produce the
correct size. Now I have a sheet of sandpaper torn neatly into 4
equal pieces. See below.
This is the easiest way I have found to accomplish this little
