WR&N IV Animation: Firehouse Doors

The firehouse with opening doors was something I'd wanted to do for a long time. The mechanism is relatively simple: A low-RPM motor with a threaded rod moves a lever that lifts the doors (a pair of microswitches limit the travel). To add visual interest, the two doors do not open simultaneously; instead, one lags behind the other. This was accomplished by mounting a pin on one door that engages a pin on the other; the pins are separated a little to stagger the action.

The firehouse now resides on Rick Spano's Sceniced and Undecided.
