BW March 2018

3/2: I ran one test in the morning on bundle 401, but the graphs did not look right. I talked with Jim about that, and he said we should ask Dr. Jones. We did not have a chance to address the issue.

I polished the bundle of sci-fis with 1000 grit until I decided I had gone on long enough, really too long, and it was time to change to 5 micron grit. I was consistently measuring a length around 0.798", which is acceptable since the goal is a length of 0.787" +/- 0.039". For the next bundle of sci-fis I will polish away more with the 400 grit. Maybe I should start using the 1000 grit when I am 0.012" from the goal of 0.787".

I polished one end of the bundle with 5 micron grit and started on the other end.

3/5: I ran one test this morning but after that the tests wouldn't complete. Jim said I should ask Dr. Jones whether the problem from Friday was solved before doing more tests.

I practiced fusing again. Last month after Jim worked on the splicing unit I couldn't adjust the left pressure regulator. Today I found that if I pulled the knob up, I could twist it easily.

I polished the sci-fi bundle some more. I picked the end that looked better after the 5 micron grit as the fuse end. I will continue polishing the other end with finer grits, but when I get to the copier paper I want to see if that will improve the fuse end as well as the free end.
