=== Abrasive Dimensions ===
The video linked below describes the procedure very well but the dimensions for the new abrasive don't seem to be available anywhere obvious. Tracing the old paper may be viable but if it's stretched, ripped, or you otherwise need to start from scratch, see the following diagram and procedure.

(not to scale!)
# From one square cut edge, measure 12' and cut another square edge. You now have a strip of abrasive 144" long and 4" wide.
# Measure 13.5" from one end and make a mark on the back of the paper. Trace this line to the nearby end's opposite corner, making a diagonal. This 13 1/2" x 4" right triangle defines the first "tail." Cut along this diagonal to make the first end pointy.
# Measure 3.5" from the point. Draw a line perpendicular to the diagonal edge. Cut this off to make the pointy end stubby.
# Repeat this procedure on the other end **but on the opposite edge.** That is, make a (blunted) rhombus, not a trapezoid. You now have two tails on your long strip, one "facing up" and one "facing down."
# Refer to the video on how to install this into the machine.
