John,<br><br>Can you build a steel frame with outriggers that are perpendicular to the plane of the door? See the attached PDF. You could add another set of outriggers on the other side of the door for more strength.<br>
<br>If you use a pair of steel frames 6" apart with welded spacers every 2' or so, you will get a lot more stiffness. You can attach the door jambs to the pair of frames. <br><br>The size of the outriggers depends on the steel you have. I would guess that 1" or 1.5" would be enough. Add plates to fasten them to the floor (at the ends and at the door) with stage screws or drill holes and use bolts. Put screw plugs in the stage floor so they can be struck and reset without damaging the floor..<br>

<p class="MsoNormal">Greetings all!<u></u><u></u></p>
<p class="MsoNormal">So, one of the scenes in one of my colleague’s directing class requires 2-3 door slams per page of script. Naturally as a class project there is no set for them to work on so everything has to be portable. I would anticipate between rehearsals
and the presentation there will be 100-150 slams of the door. Does anyone have a design for a door that can take that sort of abuse and remain free standing? I can fasten to the floor for the scene or add a bunch of weight if needed. I have the capacity
to do light steel work and carpentry in house; the doors I have in stock are mostly hollow-core doors.<u></u><u></u></p>
