Line 112: − − 6/4: I practiced fusing today. For a while I was getting adequate strength but also wings. I would like to start fusing, though, and test a bundle to see if wings really matter. If we remove them and the fibers work, I think there is no reason to complain. If we run into problems with the first bundle, it won't be a major delay. We can cut off bad fuses and redo things. − − I need a list of things to do next. − − 1. Ask Dr. Jones about the lips and why they would interfere with fusing. − − 2. Explain what happens during fusing in more detail. − − 3. Find out how to drain the Campbell Hausfeld compressor tank. − − 4. Start cleaning sci-fi bundles with the new lint-free cloths.
→Jim on Color Codes and Fusing
A lint-free cloth does clean the fibers, but it can move some dirt down to the end where it should not be. It would be good if we could use compressed air to clean the fiber cladding and ends before fusing as well as using a lint-free cloth. Even compressed air might mess with the cladding, though, so we should be careful with it.

Jim and I talked while he was working on getting the ferrules back in the splicing unit.

I said I thought if I fused rough cut fibers strong enough, I would definitely fuse polished fibers strong enough since the polished fibers have much better contact than rough cut ones. But Jim said the rough cut ones with their rough surface might absorb more light and heat up more than polished fibers. The light might be more likely to shine through polished fibers and not heat them as much. We don't know for sure, so it is best to polish the scrap fibers before fusing and weight testing them. We only need to polish as far as 5 micron grit, though.

Andrew and I started testing spare bundle 408 today.
