Everything began about 10 years ago when I bought a used Elmo ST1200 M/O. The seller declared problems with the projector so I kind of knew what to expect.
Once I received the projector I immediately understood the nature of its problems: apart from the melted belts, the rubber that surrounded the shutter was
also melted (Editor's note: missing or damaged rubber on the shutter can be remedied with a Shutter Belt
Replacement from The Reel Image!).
Clearly it was necessary to clean the projector and the shutter from all the melted rubber, but this is where the big problem arises: the profile of the shutter
when the rubber is missing becomes tapered and it can no longer guarantee perfect adherence to the rubber wheels. This results in
poor adherence that does not maintain correct speed of the projector. Moreover, this condition stresses the bearings to cause anomalous
noise and wear!
At this point I tried to find a Type 2 shutter, but that's not an easy task. This led me to consider having the Type 2 shutter produced at a mechanical workshop
to simply replace the old Type 1 shutter.
Since the processing would have been complex regarding the shutter's three windows, I thought to consider the option of two windows to reduce
the difficulties of processing (since the projector would always be used at 24 frames/second.) That's how the 2-Bladed Shutter design for the
Elmo ST1200 was born!
Normally the shutter of a projector is a coaxial plate disk to the cam of the claw which is powered by a belt. In the ST1200 series of projectors the shutter
also has the fundamental task of transferring the motion of the rubber wheels to the whole mechanics of the projector!. Here then it must be much more robust
and well done to avoid malfunctions of the projector!
Once I studied the case I created a 2-blade shutter using a CAD drawing program and then brought the design to a mechanical workshop whom I
contracted to fabricate my 2-bladed shutters.
The result is an expert mechanical craftsman has made the finished component! You can see it on the right side of the picture below:
The benefits of this 2-Bladed Shutter design are these:
