In HAM 4, today I:
-
Replaced the 4 errant blade tip EQ stops (required use of tweezers) discovered yesterday.
-
Used the canning cone to spray FirstContact onto the SR2-HR surface in order to reinforce the thin sheet already on it. This is in prep for pulling the sheet later - it occurred to me to do this now since I am installing other HWS/Baffle items close to the SR2-HR and spraying FC later will require moving it all again.
-
Suspended the masses and rechecked with quick TF that chain is free of mechanical interference.
-
Reattached and realigned all 14 OSEMs in 6 DOFs, each.
-
Finished attaching and tightening balance of dog clamps to SR2.
-
Discovered that there is a missing cable table bracket.
-
Attached witness plate and 1" witness optic holder into places.
-
Set 1 of the HWS baffles in place on the table - cookie cutter didn't look quite right.
-
Set the SR2 AR baffle into place - again the cookie cutter didn't look at all right.
-
Set the SR2 Scraper baffle into place - same story, cookie cutter isn't quite right. Also, discovered I don't have the correct AOS washers which are used on the unique scraper baffle hold-down clamps.
-
Stopped to go figure out what the heck is up with the cookie cutters, and find specific washers.
