→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.

I also bundled the spare bundle and I am about to polish it. However, I have some misgivings now about whether I correctly identified the spare bundle (bundle 408). It is supposed to have a cyan strap, but it does not. I put a white strap around it for now. I do see one or two cyan straps in the storage box. I wonder if one of those is marking the spare bundle. I should check the color codes.

When I checked the color codes, they matched the records of spare bundle 408.
5/9: I looked for canned air on amazon.com.

We can use the small compressor for painting to provide air to blow off the fibers.

5/22: I had the horizontal pressure in the splicing unit around 20 to 25 PSI early this morning. I had to push to get the fibers to fuse. Then I raised the pressure over 30 PSI and I started getting wings when I pushed just a little.
I found a [https://manuals.harborfreight.com/manuals/95000-95999/95810.pdf manual for the Central Pneumatic Deluxe Air Brush Kit]. I am not sure if we could use that tool as a nozzle for blowing on the fibers. It is meant for spraying paint, so probably it would not be the right choice.
Dr. Jones said the small compressor would probably not do the job either, though I could try it. It is a [https://manuals.harborfreight.com/manuals/95000-95999/95630.pdf Central Pneumatic Mini Air Compressor]
5/29: We cannot use the Optik Wipes as lint-free cloths for the fibers because they are wet like baby wipes and they contain 1-propanol.
I moved and added color codes to all the fibers in spare bundle 408.
5/30: Jim brought me a camera memory card reader and said I should have a main folder for my pictures and subfolders such as for each date I took pictures. In each folder and subfolder there should be something like a ReadMe Word Document to explain what is in the folder and what is particularly important. If there are any other files such as for programs in Python or LabVIEW, I should also explain those.
Andrew finished polishing the short fibers today. There is one bundle still in the collar, but I should take it out soon.
5/31: I need to get canned air tomorrow. I put some long fibers with lips on the table with the drill press and the saw. I want to discuss them with someone because I don't see how they are interfering with fusing.
Andrew and I started testing spare bundle 408 today.
