BW January 2014

On January 2, I helped straighten a bundle after cleaning a bundle that had already been straightened. Then I revised an old version of the straightening procedure and typed two other procedures.

On January 6, Liana and I emptied and dried the fish tank, washed it with warm water, and dried it again. We polished light guides. It took me much longer than it took her. I might have been pressing too hard. I measured the length and width of 30 scintillating fibers. I counted scintillating fibers and put them in relabeled bags.

On January 7, I learned how to screw the collars onto the Unistrut bar. I scraped rust off the bar with a damp cloth. Kenny and I made two bundles of fibers for Brendan to mill. The collars have to be 65 10/16" apart on the outside. I polished a bundle of light guides and then polished some individual fibers that had not been polished enough in the bundle.

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 sci

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.
