Bamboo bow for a wind muscle

This is a 27" bamboo bow made by splitting a 1/2" diameter cane to 3/16" width. With a wind rotor made from 8 fluid ounce foam cups, it easily twists a single strand of 1-lb test Dyneema fishing line to solenoidal, even in a zephyr-like 1.5 m/sec. breeze. Stroke is about 3".

Not much of the fiber length is becoming solenoidal. No extra twist was built in.
