Assembling the Shutter Barrel
Tools Required:
• #2 Phillips head screwdriver
1:
Stand the top and bottom shutter barrel castings (1 and 2) upright with the shutter end of the
castings toward the bottom.
2:
Slide the bottom divider plate (4) into its place in the bottom casting (2). The dimples on the
divider plate must point down.
3:
With the bottom barrel casting (2) to your left, place two shutter blades (3) on top of the dimple
plate (4) and opposite each other so that together they form a barrier. The handles should extend
past the barrel casting, rivets pointed down. These will be the side shutters (See
Figure 13
).
4:
Place a divider plate (5) on top of the two shutter blades.
5:
Place another shutter blade on top of the middle divider plates and perpendicular to the
previously installed shutter blades. This will be the top shutter, so align the handle away from the
bottom casting (2) and then place the other divider plate on top.
6:
Place the fourth shutter blade on top of the divider and through the bottom casting in the final
shutter position. Pull the blade and plate assembly slightly forward to allow the handle to slip
through the slot in the bottom casting, and then fully seat the blade assembly into the casting
again.
7:
Place the top divider plate (6) on top of the fourth shutter blade.
8:
With both shutter barrel castings still standing upright, join the two halves, sliding the handle of
the top shutter blade through the slot in the top shutter barrel casting (1).
9:
Starting at the bottom of the castings (closest to the shutters), use four PHMS screws (9) to fasten
the shutter barrel casting halves together, as shown. Hand-tighten only (2.8 Newton meters).
WARNING:
During assembly, the shutter springs can pop out of place. Always wear
protective eyewear during this procedure.
Note:
The top shutter barrel casting contains the iris slot.
Note:
The bottom divider plate (4) has four dimples punched into the surface; the top
plate (6) has none. The middle divider plates (5) are noticeably thinner-gauge metal
than the other two.
The notches on the divider plates must fit against the flanges in the casting so that
the plates do not move.
WARNING:
Divider plate edges are sharp. Handle with caution.
Note:
Make sure that no shutter assembly components are under the gobo holder guides.
Note:
The ends of the two shutter barrel castings must be even. Adjust them as necessary
before completely tightening the nuts and screws. Failure to do this could interfere
with the barrel rotation.
