This is easily one of the most ambitious projects ever tackled by Bryant Hornet Engineering - a powered 18' turntable for the stage in Love Auditorium for use in the Theater Department's 2015 production of Les Miserables.
The turntable can support a live load of over 3000 pounds. It can then be disassembled (removing 8 bolts under access panels) into five pieces that can handle up to 600 pounds each, while floating freely about the stage (for use in future productions). Each piece can easily fit though a standard size door for storage and transport.
The turntable is powered by a pair of electric motors pulled from Bryant Hornet Engineering's EV (electric vehicle) Racer. Each motor is rated at 1.5 hp when supplied with 36V. We applied 48V for a little extra grunt (as they are supplied when mounted in the racer).
The controls were simplified down to nothing more than an on/off switch and a simple dial control that would start the table and control its rotational speed.
The turntable was constructed and powered for just over $900.
Early runs did experience complications when the table was heavily loaded and the chain lost traction on the circumference of the table. This was remedied for the final two performances, resulting in a great effect for a remarkable performance.
Congratulations to the cast and crew on an incredible show of unprecedented awesome. BHE was glad to be part of this amazing event.
This is a great example of how our PLTW classes and projects interacts with other programs and departments on our campuses.
A special thanks goes out to Matt Hilton for his help in making this happen.
