A Midsummer Night's Dream

 The spiral staircase platform was a project to create a temporary spiral staircase tower that could be removed from the stage for an event overlapping with the show's run.  The specific needs of the tower required a steel base to support the height of the tower and prevent movement caused by actors using the staircase.  We achieved this by building a platform to house a pneumatic pivot point.  This circular platform was formed with a steel frame and allowed for the pivot point to be removed and installed in a different platform if needed. This allowed for the platform to enter stock as the pivot point did not need to be stored with it. After using a metal bender to form the circles that made up the frame, we welded trust supports to connect to the pivot point housing.  We then attached pneumatic brakes and zero-thrust caster boards. On top of this platform, we installed the spiral staircase and sheeted the tower with revolution ply.  The pneumatic switches were run to a hiding space next to the stairs' railing, allowing actors to easily engage and disengage the pivot point and breaks.
