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 assembly.
  • 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:
  1. pre-load bolts into cube tube CF flange.
  2. put on magnet (with no 4.5 dummy flange) and push it against cube face.
  3. bolt on actuator.
  4. move magnet against acutator.
  5. bolt in dummy 4.5 flange spacer.
  6. bolt magnet to dummy flange.
