Installing and Removing SHARP Box 4

by Giles Novak, November 18, 2013


NOTE: While maneuvering Box 4, do not set it down on its bottom or back sides, to avoid damaging the protruding 
glass gold-coated mirror.  You may set it down with its top or front sides facing downward as these faces are flat 
metal surfaces with nothing protruding.  (By "front" I mean the side with the arched cut-out that faces the 
incoming photons.)


Installing Box 4:

STEP 1: Set Box 4 down on Box 3, trying to match the cutout on top of Box 3 with the cutout on the bottom of Box 
4.  Box 4 will locate via alignment pin.

STEP 2: Use two cater-corner flathead bolts (inside Box 4) to attach Box 4 to Box 3.  Finger-tighten with Allen 
key.

STEP 3: Install the two brackets that secure Box 4 to the parallelogram-shaped extension to the "SHARC-II tower".  
The "extra spacer" goes on the far side.  Do not over-torque the smaller bolts that connect the brackets to Box 4 
as the threads are aluminum.  Use washers here as needed.

STEP 4: Install the two Box 4 near-side "side panels".  One panel has a cutout for the above-mentioned brackets.  
Each requires just two small bolts.


Removing Box 4:

Execute the above four steps in reverse, and be sure to save all hardware carefully in a plastic bag that is to be 
stored with Box 4.  Box 4 should be laid in its crate, on its back.

Put the "Box 3 cover" on top of Box 4.  The box 3 cover is "L-shaped" and has a hole to match the pin sticking up 
out of box 3.  It is held in place by gravity.
