 I started working mainly on production this month. This involved learning the procedures for measuring, straightening, fusing, and painting the fiber bundles. Below are things I've learned are important to look for during production:
-'''Measuring:'" The lab completed all rough-cut measuring of all the bundles this month! Kenny is the fastest at measuring. We found that one of the micrometers sticks at a point and is no longer in use.

 '''Straightening:''' Make sure the anchor screws for each collar are evenly tightened and tight enough to not become angled due to the tension. Also double check the 5x6 matrix before inserting the fibers into the PVC.

 This month was spent almost exclusively on bundle production.
-Fusing:  I have been fusing a lot with Keegan or Jon. Usually one of us is actually operating the fusing machine, and the other is measuring light guides, sanding the lips of the fuses, and measuring the final fuse joint. This is more efficient than just one person fusing. Just myself fusing it would take about 4 hours but with two people, it can take anywhere between 2.5-3 hours.

 I updated Jim's fusing procedure from a few years ago and put it on the wiki. I believe Keegan added photos to the procedure and updated formatting.  There were a few things that had to be specified from Jim's procedure. I mentioned the need to observe the pressures after starting the fusing unit.
-Straightening: I've been straightening a bundle about once a day/every other day. It's been going well. I've helped Ann Marie plot the temperature data for the a few bundles to put into her Google Doc.

 There hasn't been any painting to do since the bending process has been stopped.

-Fusing: Always watch the pressure gauges. For an instant after the light turns on, the pressures drop. Make sure that they return to the appropriate pressures while the fibers begin to fuse. Also, putting a little bit of downward pressure on the light guide will help the fibers stay flat within the ferrules.
+'''Painting: '''Be extremely wary not to put the paint gun too close to the fibers to cause run-off or bubbles. Also be careful and thorough while cleaning the paint guns. Painting was only done in the first week or two of December. I know bending was halted before intermission, so there weren't any bundles for me to paint this month after the 16th.

-''Sept 29- Oct 5 (7 hours)''- This week I finished the rest of the drawings Alan required for the back plane to be machined. I discussed with him the parts that we'll need for machining: 2 boxes of tap pieces, 1 end mill, and the aluminum. After that was finished, I worked on the AutoCAD drawings of the various parts for both the Gluing and Bending stations. I had previously worked on them so I just finished and printed. And finally on Thursday, Oct 3rd, I cut and sanded some scintillating fibers for Ann Marie to fuse, and I also broke some fibers which she had previously fused. All the information I recorded went into a Google Doc and was shared with her.

	'''Sept 22-28 (Total: 7 hours)-''' Because the part is 61" long, I decided to do 4 "windows" so that Alan can properly cut the part. The middle two windows are identical in length of 15" so that Alan only has to program 3 times instead of 4. I finished the drawings for window one this week. It required three separate drawings to properly and cleanly represent all of the holes. I will have to wait for Alan to come back from vacation until we can discuss the locations of the construction holes etc. Jim got me the dimensions and taps of all the holes.

	'''Sept 15-21 (Total: 7 hours)-''' This week I spent a lot of time working on drawings. Last week there was a miscommunication, and I have to create a styrofoam cut-out for the microscope all constructed. This will be done after I finish the drawings for the backplane and chimney. Thursday I talked to Alan and discussed the TurboCad drawing for the backplane. It will require multiple drawings and construction holes 0.375" dia and 6" apart. Hopefully we can find a place to split the drawing well to take advantage of the many arrays of holes.		'''Sept 15-21 (Total: 7 hours)-''' This week I spent a lot of time working on drawings.
