The document summarizes the process of preparing and cutting the last third of a photoframe. It describes putting on protective gear, taking the blade out of a coping saw to cut the inner shape of the photoframe, and then using a pedestal drill with a drum sander to trim and smooth the edges. Figures are included to illustrate the cutting process. Safety rules for using power tools like ensuring blades have stopped before turning tools off are discussed.

1. DT Process Journal Feb 11th 2011<br />- Preparing and cutting the last third photoframe <br />Today I worked on creating the last third photoframe as I completed cutting the backboard. I first wore an apron to protect my body from dust and put hard shoes to keep my feet safe from falling sharp tools. I should have preparation for cutting the photoframe. It was necessary to take the blade of coping saw out and put the blade in a hole of photoframe. This way allowed me to cut the inside part of the photoframe to shape the perfect water drop. Therefore, I first pushed the edge of coping saw with my shoulder’s power (See Fig 1). One side of the blade them came out (See Fig 2) and I put the blade in the hole of the photoframe (See Fig 3). I pushed the edge of coping saw with my shoulder’s power again and put the blade into the coping saw again so coping saw could work. After accomplishing preparation, I started to cut the inner waterdrop shape of the photoframe (See Fig 4).<br />Figure 1: I was pushing the edge of coping saw with shoulder’s power. <br />Figure 2: As I pushed down, the blade was taken out from the coping saw.<br />Figure 3: I was putting the blade into the hole of photoframe to cut the inside part of it.<br /> <br />Figure 4: I was sticking the photoframe to the bench hook and cutting it.<br />- Trimming the photoframe<br />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 5). 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.<br />Figure 3: 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.<br />- AOI / Learner Profile<br />Today’s process 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 <br />- Emotion / Changes to Plan<br />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.<br />
