2017-09-04
Main Assembly Sequence
Crane out SF.
Raise BF cap and retrieve lost hex cable clamp PEEK piece.
Crane in SF.
Install SF-BF rod with hex cable clamp.
Route cables via hex cable clamp up to below SF.
Adjust BF ballast mass for total weight and pitch/roll.
Look for missing screw from SF damper Cu segment in washed screws bag and reinstall.
Adjust yoke on SF to put top of secondary at 6 mm above top of baseplate (or to give ≈0 counts at nominal height).
- Calibrate SF LVDT.
- Install SF main ballast mass.
Cable and test SF fishing rod stepper.
- Add SF cap.
- Lift and weigh SF/... section.
In parallel, time permitting
Rearrange arc weights on PI to allow installation of magic wand.
- Install magic wand on PI.
- Check that we still have all LBB parts (there was an issue with borrowed lock nuts).
- Rearrange magnets on SF damper magnet ring for full three Cu segments.
Find Ni-plated rods for SF damper magnet ring and do fit check.
Find PI-SF rod with 8 mm heads and matching receptacles and do fit check.
- Lay more new in-air cabling.
- Wipe LLB damper parts with ethanol.
- Get Cu O-rings for feedthroughs.
- Figure out how to tighten PI yaw return spring.
Recalibrate remachined LBB springs and choose best three.
Tasks Not To Forget
Major Tasks
