Measure a smooth straight brooomstick into 6 parts. Cut the broomstick into 5 pieces, making one piece twice the length of the others. (use as the center with a hand-hold) Use notebookpaper and scotch tape to make the bands. Line up the rollers on end and run a strip thru them to get a measure of the strip length needed, then cut the other strips to match. Taping it together is a bit difficult. A table knife can be used to help lay the tape flat. It may also help to run a piece of tape perpendicular to the paper strip to help make sure the tape holds.

C-Shaped belts are arranged in an alternating pattern. This offset pattern creates balanced "tug-points", separating and stabilizingalong the rollers and locking them into parallel rotation:

Tug-points (symmetrical)

Note: "Remember to use FLEXIBLE yet NON-ELASTIC bands"

Longer rollers may require a greater number of belts and/or wider belts to stabilize the rollers along their length
