BW April 2018

4/2: I sanded several thick fibers in bundle 405 to get them through the chimneys more easily. Andrew put the fibers back in the collar and aligned them before I left, but we still wanted to improve the alignment. I recorded the new configuration and tried to improve the alignment, but a Kapton strip broke and after I replaced it I did not get a very good alignment.

I also practiced fusing today.

4/4: This week I started polishing a fourth bundle of sci-fis. I am still twisting right in front and left in back.

Yesterday during fusing practice the hook on one of the 500 g weights broke, and today Jim suggested wire as a replacement.

I worked on preparing light guide bundle 403 for testing today.
