[Frameworks] telecine projector question

[Scott Dorsey]

Most JAN projectors are 3-blade.  The 5-bladed ones are noticeable dimmer on
a screen.

I _think_ that shutter is for a 500-series or 1500-series B&H.  Replacing
the shutter is a major pain in the neck.  I have replaced the worm gear
on a 500-series and it was about an eight-hour job... getting to the shutter
is nearly that difficult (and frankly if you're going to put a 5-bladed
shutter on a 500-series you might as well change the worm gear while you
have the whole mechanism apart).  Optech charges about $400 for worm gear
replacement... they would probably charge about the same amount if you wanted
a new shutter in the process.  In fact, they might even have a spare 5-bladed
shutter in the junk box somewhere.
