- Marking out the last third photoframe During today’s workshop, I had accomplished many works for creating my product. I began working after I put apron and hard shoes. I finished making two photoframes and today I marked the last third photoframe that would be a mirror. I marked this one much bigger than others, size of 220 x 240 mm because user should be able to see their face in the mirror. I draw the side line with tri-square and metal ruler than draw the middle line in that rectangle to make more stable waterdrop shape. Pinewood was used for the last third photoframe as usual because it is strong enough that increases durabilities of the product.

Figure 1: I was marking out the last third photoframe on pinewood. I used pencil, metal ruler and tri-square ruler to mark it.

- Preparing to cut the backboard I should set up 125mm size of G-clamps to cut the backboard using a jig saw. Because the backboard was big, bench vice couldn’t hold it while cutting the backboard. Even the jig saw was powerful machine tool, I needed G-clamps to fasten the backboard tightly to the desk so it wouldn’t move. If it moved while cutting with a jig saw, I would get over the pencil line and cut the wrong parts. Therefore, I used two G-clamps to protect the backboard from moving while I cutting it with a jig saw.

Figure 3: I was sticking two G-clamps to cut the backboard. The clamps were firmly fixed on the backboard so protected the backboard from moving while I cut it using a jig saw.

- AOI / Learner Profile 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

- 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.
