Something that I have been doing lately, and I don't claim to have invented it, is to use hemostats to hold the ends of the rubber together. Follow Bill's technique but clamp the hemostat to just cover the ends of the rubber strands. Then pull the knot up to the hemostat tightly by spreading the two strands. Put in a second knot and pull it up to the first. When the hemostats are released, just the right amount of loose ends are left and no tweaking to get the right weight is needed.

Tie one overhand knot as close as possible to end of motor, then spread the strands to move the knot as close as possible to the end of the motor. Tie a second overhand (or underhand) knot inside of the first one and spread the strands to move the second knot tight against the first one.
