After a serious round of fit checking on Monday (going through the motions on the wrong optic), Danny yesterday in my absence glued the first primary prism onto MC2.  It cured at room temperature overnight.  The fixture was removed this morning and the prism is now under a heat lamp cure until ~3pm this afternoon.

The setup for the fixture which requires the ability to use a horizonally mounted height guage is still flat out dumb.  After ~7 mods to parts, I've recreated Danny's setup at LLO (kudos for getting the poor design to work at there!), but we still find that the multlitude of bolted together stages do not hold the long lever arm of the height guage steady enough.  As well, we are still hand pushing the jig fixture around to acheive the 0.1mm tolerance on the placement of the prism (no micrometers!!).  I do not see how we can continue to use the exsisting fixtures for 13 more optics (H1 and I1), without sacrificing serious efficiency (and my mental health).  So, I'm going to try the iLIGO gluing fixture on a spare optic, in parallel with fussing through the cobbled together setup we have now for the 2nd MC2 prism.
