Changes

On January 8, I went to the machine shop with Jon to pick up a milled bundle. I put a bundle on the Unistrut bar to be straightened, and I cleaned some fibers that Jon had polished.

On January 13, I polished bundles of scintillating fibers. Sometimes when I put fibers into the collar, I noticed some static cling between the fibers and my gloves and also between the fibers and the collar. The attraction to the gloves was not helpful because the fibers would fall out of the collar when I drew my hand away. The attraction between the metal and the fibers, however, was useful. It can be a tight squeeze to fit the last few fibers into the collar,

On January 13, I polished bundles of scintillating fibers. Sometimes when I put fibers into the collar, I noticed some static cling between the fibers and my gloves and also between the fibers and the collar. The attraction to the gloves was not helpful because the fibers would fall out of the collar when I drew my hand away. The attraction between the metal and the fibers, however, was useful. It can be a tight squeeze to fit the last few fibers into the collar, but not so tight if the uppermost fibers are stuck to the top of the collar.

On January 16, I began to bundle light guides for milling by myself. I put a collar around the fibers at one end, then put another collar on at the same end. Once the second collar was tight, I slid the first collar toward the other end of the fibers. Then I noticed that at certain points there was a gap between the fibers in the bundle and the collar even though the collar was tight. Consequently, a few fibers could slip even though most could not. I brought the problem to Ann Marie and Liana, and Liana came over to fix the problem. Eventually the fibers were tight to our satisfaction.
