35mm and 70mm Readers, Switchable, Using the Same Bracket
If both 35mm and 70mm reader heads are to be used on the same bracket, add spacer breakaway plates to
the readers. They are added to allow quick changes between the two. Keep the plates attached to the
readers and maintain them as a set once the projector alignments are finished. See below.
1. Start by mounting the 70mm reader (with its breakaway plate attached) to the bracket.
2. Use 70mm film to align the reader. Once aligned, tighten bracket screws.
3. Loosen the thumbscrew on the breakaway plate so that the 70mm reader detaches
from the bracket.
4. Next, attach the 35mm reader (with its breakaway plate attached) to the bracket.
5. Use 35mm film to verify the alignment path is correct -- no corrections should be
necessary.
The goal is to have one alignment for both readers so that no projector adjustments are needed
when the readers are exchanged.
