EQ stop preparation
- Talk to Zach - help him get started on this
- Plan for viton cutting (something to help measure / keep the razor straight while cutting)
- Cut the Viton
- Assemble EQ stops (stick the viton in the screws)
- Tues 23 Feb
EQ stop preparation

ITMX/ITMY baking - done
- Remove both ITMs from their suspensions (Morning) 2 person job
- Vacuum bake to clean the optics - 48 hours
- Leave the 2 ITMs alone in the bake oven
- Get RGA scan to confirm they're sparkly clean
Mon 5 Apr (actual date)
Final Prep for Installation
