Big rubber bands (as from a hobby shop: used for rubber band powered model
airplanes), or a bicycle inner tube (from a smallish tire/wheel) also make
nice improvised low speed belts.  Another trick is to put something like a
skateboard wheel (no bearing!) on the motor shaft, and then push it up
against the form.  The speed ratio will be the ratio of diameters.  Rubber
hose over the motor shaft also works.
