HAM5 optics ready for FC

After the SEI guys let me know HAM5 ISI was locked back up I went in and locked the face stops of the intermediate and bottom mass of the SRM and SR3 suspensions. I then used dog clamps upside down to mark the position of the baffle in front of SR3 and removed it so that the SR3 optic can be first contacted.

I then had a look around both suspensions and noticed that a lot of EQ stops were a long way back. I have gone around both suspensions using an inspection mirror/light and moved EQ stops closer and locked (as best I could) the EQ stop nuts so that the EQ stops should not move. This includes moving three of the 4 EQ stops underneath the intermediate mass of SR3 closer (I couldnt get an an angle to adjust the fourth one closer, but I could do up the nut). When it comes to unlocking and locking the suspensions from now until closeup should only require moving the face stops of the intermediate and lower mass.

 

The suspensions should now be ready for first contact to be applied

 

I also whilst in the chamber wiped out the inside of the bellows, etc. If you asked me if it was necessary, see the pic for an example of the sort of stuff was getting on wipes when wiping out the bellows
