DT Process Journal Feb 11th 2011 -‐ Trimming the photoframe After cutting the inner part of the photoframe, I began trimming the photoframe with pedestal drill. I first wore goggles because a large amount of dust came out from the machine. However, I didn’t use the sharp drill,which we required to drill the holes. I used a round drum sander to make the surface smooth. I adjusted the height of support to trim wider space. As the drum sander was spinning so fast, I pushed through the wood so the rough surface could be peeled (See Fig 1). When too much dust was sticking to the drum sander I should rub it with rubber stick to remove the dust and worked with it more effectively. In addition, I used a disk sander to trim the outer surface of the photoframe. When working with the disk sander, I had to flat down the wood and I should not go over the space where x was marked. I also should wear goggles to protect my eye from dust (See Fig 2).
Figure 1: I was using pedestal drill to trim the photoframe. The red round thing is called ‘Drum Sander’ which peeled the rough surface of the wood.
Figure 1: I was using a disk sander to trim the outer surface of the photoframe. I was working on the safe place where X was not marked. -‐ AOI / Learner Profile As same as the other day, what I had done today was related to Approaches to Learning. I learned some safety rules dealt with jigsaw: First, I needed to push it down while it was working. Second, I should wait until the blade finally stopped moving when I turn off the machine. With the regards of Learner Profile, I was a communicator during the workshop. Although I used a jigsaw before in grade 9, I forgot how to work with it. Even I was scared to use it because I could felt the vibration jigsaw made while it working. I was able to manage this difficulty by asking for teacher’s help. Teacher showed me a demonstration of using a jigsaw and also he informed me some safety rules that I should obey when working with a jigsaw -‐ Emotion / Changes to Plan
Today’s process was satisfying for me. As I predicted in the flow chart, this trimming process took long time. However, it took much shorter to make the edge of photoframe smooth. I could move to next process quicker. In addition, I was a bit scared to use gig saw because of its great vibration. Therefore, today’s work was successful.
