Up late after work - watched some of "It Should Happen to You" on TCM - there was a Pete Smith short on afterward, "Curious Contests." Among them was a segment entitled "Train Wheel Twirling," which took place in, the announcer said, a railroad yard in Virginia. Men on a stage, doing various tricks with wheels from rail cars. The fellows get them spinning on an edge, dash from one to the other, or move them through a slalom course of lit candles.
EDIT: I just watched it again. It's at a Norfolk & Western site - there's an N&W RY sign on a building, surrounded by "Be Careful," "Safety First" and another word or phrase ending in "ly" (Work safely?) that is obscured by people watching the event.
One fellow uses his left hand to keep the wheel rotating, while his right inserts legs into a disc to make a stool; then he hammers them in, while keeping the wheel spinning. Turns the stool upright and sits on it, while keeping the wheel in motion.
Wish I could post it, or link it - can't find it online. If you recorded the Judy Holliday-Jack Lemmon-Peter Lawford movie, watch the short. It also may have been included as an extra in a DVD of "Pagan Love Song."
