He also pointed out that there seems to be a bit of debris caught under the 1000 grit sandpaper that is scratching the fibers.

I fused four fibers with lips, one with each possible orientation of the lip. Front top and bottom are the positions closest to me as I was fusing and back top and bottom are farthest from me.
After having a Google Hangouts meeting with Dr. Jones and Jim, I started trying to push just until the clamps started to move. They are supposed to stop moving when I let go. I have not seen that happen, though. The clamps do keep moving as I suspected. But I might be pressing too hard or too long. I might not notice exactly when the clamps start to move.
6/8: I forgot to test the splicer before using it. Fortunately the ferrules did not slam. I will have to be more careful in the future.
6/11: I want to make a plan for fusing. Today I had some problems at the beginning but as I went on my fibers were strong enough and looked reasonably transparent. If I am getting good results like this, I want to move on from practice.
However, sometimes when I thought I was ready problems arose and I changed my mind. Last week, I had a string of successes and I thought I was ready, but then a series of failures stopped me from moving forward.
This week, though, if I let the machine do most of the work I may be able to avoid a long string of problems.
I do need to address some questions, though.
* Should I measure the sci-fis before fusing? Is that something we have done in the past but don't need to continue or is it something that is still essential?
* Is my plan for spares all right?
* Do the fibers need the same testing configuration as in the pre-fuse tests?
* If I make a bad fuse, I need to do some good practice fuses before continuing. How many should I do?
* Where will I put light guide bundles after I take them out of the storage box for fusing?
* Where will I cut off wings?
* How will I have clean surfaces ready for the fibers?
I should plan what I need to do before and during fusing:
* Clean the scrap fibers for use as we are fusing the replacement fibers. Set aside scrap fibers that have unacceptable adhesive residue.
* Clean the splicing unit, especially the clamps and ferrules. Keep them and the surfaces that would be in contact with replacement fibers clean.
* Clean the replacement fibers before fusing them.
6/12: Yesterday I finished polishing the scrap bundle end Andrew was working on.
6/13: Today it seems that any lip, no matter how small, is ruining fuses. The first fuse is incomplete and dimpled, and the dimple does not go away. The corners are not perfect either.
I think I need to start putting the fibers in the right orientation when there is a lip. That will be more difficult than my normal practice using the tape, but it is possible to do. Maybe I will need to record which way the tape is facing on the first fuse so that I can turn the fiber over correctly for the second fuse.
To remove wings, I can hold the wing pointing up vertically and scrape going both ways.
6/18: I am starting to fuse bundle 404, and I will be starting with Sci-Fi bundle 3.
