Tech Reflection

Today during tech since I'd finished my creation the last week I was just finishing off my workbook, as well as changing it to be better detailed so that I could get better marks for my report. At first I needed to change the aspects of the workbook, next I changed the tools/techniques and after that I finished off the part where I wrote what I would do differently if I could. This was the second to last week of tech, so next week if I want to make a box to hold my creation then I'll need to hurry up because it takes 30 minutes to dry the glue.

This week in tech for pewter casting the only task was to finish off sanding the castings, I started off the class using the 400 grit but when it ended I'd made it to 1200 grit. To sand the designs properly we needed to rub the sanding paper onto the edges and the sides a lot to make them feel soft, for every stage of sanding before you could advance into the next one you needed to show your work to Mr Grundy so that he could check it. If he thought that you'd done a good enough job he'd give you a better piece of sanding paper, and then the sequence would repeat. The final stage of sanding is the 1200 grit piece with water, after that a liquid is wiped onto the design which makes it look shiny.

Today at tech we were tracing our designs on a wooden square, cutting the traced design out and filling it with pewter. I wasn't able to cut mine out but I have finished tracing, the reason that it took so log is because so many people wanted theirs checked and my name was pretty far down in the list. When Mr Grundy gave us all a demonstration on how to use the the cutter everyone had to stay a metre away just in case someone tripped or something, we also had to stay behind some yellow and black tape on the floor when he was pouring the pewter into the moulds.

This term at tech the year 7 group are doing pewter casting, to start we had to create a plan. In the plan we had to fill out a list of 3-4 family members or people that we could give the finished pewter to, we also had to write own four things that are related to them to help us decide on what we should make for them. Our teacher, Mr Grundy also showed us a machine that we would use to cut the shape of our silhouettes, there are special keys to start the machine so that nobody cuts themselves on the blade (The blade goes up and down 50 times a second). He also showed us melted pewter and finished pewter pendants, as well as a tutorial video.
