; Aperture assembly instructions from Danny
*a note to phil and marcy, on the real assembly work, the bottom and right side of the cube are no problem to assemble.
*the left side (ion pump) will need studs.
*the top (with the actuator) requires a proper sequence. it might be easier to assemble it upside down.
*basically:
#pre-load bolts into cube tube CF flange.
#put on magnet (with no 4.5 dummy flange) and push it against cube face.
#bolt on actuator.
#move magnet against acutator.
#bolt in dummy 4.5 flange spacer.
#bolt magnet to dummy flange.
