Pewter Casting

3 weeks ago we continued with our pewter casting workbook, and this particular workbook leaded to creating a pendant. (A pendant is a piece of jewellery that hangs from a chain) In our workbook we write down the recipients, then write down the reason why we created it for them or myself. After we finish that our tech teacher will inform us on how to make the pendent. Then 12 of May we went to Tamaki College for Technology. At Tamaki College we learned different types of subjects, such as science, robotics, food technology and hard work material. I'm currently in hard work material. In this particular class we had to continue on with our task which was our workbooks, in this workbook it preserved information about creating our pendant. (Pewter is a type of metal that is soft and gentle, it can be easily shaped by hand or machine)  After we finished we would move on to the next step which is choosing a design, than creating that design in pewter. Today we went to Tamaki College to experience what work is like at college. I am currently in Mr Grundy's class. In this class we do  hard work material, which is creating things with wood. Today I proceeded to the next level which was cutting out my design, when we finished we would show it to the teacher for his approval  to move on to the next stage.  According to google research pewter is "A alloy of tin with copper and antimony," (Firmly, tin and lead) 

While the pewter is melting he would go help other students that are struggling. To get his attention we would yell MR! to notify him the pewter is melted. When that role is completed he would turn off the gas burner than pour it into our design holds up by another piece of wood. We would wait for at least 5 to 10 minutes for our pewter to set.  After that we would take the pendant out than smooth the edges which is where I am currently at. But hopefully I would complete my work by next week. When we finished our tech class Mr Grundy told us that we have to make sure our workbook is up to date. When it was just about time to go he said his favourite part is to see our back left the class and then he said he was joking. I am up to polishing mine pewter I really enjoy my tech class.

Pewter Casting

Today years 7 & 8 went to Tamaki College, I was in the hard materials group. when I got their Mr Grundy sanitised our hands. Then we went inside the class. First we had to talk about finishing our hard materials before we leave. After talking about hard materials we all got started into your work. When we finished talking about our hard materials we went to the table our work was on and got our box. The box had our final drawing of our pewter then we had to write our names on the board then we had to wait untill Mr Gundy called out our name. When you put your namea in the board that means you aere stuck and you need help. When we get called out we have to give Mr Gundy our pewter and he'll tell us that we have to make the sides smooth so what we did was to Make a good pewter casting neckels. So we have to write my name on the MDF, Secondly you trun your drawing over and roughly mark where it is. There after you put the pencil on the back of your final drawing. Then you place your MDF under your drawing. Carefuly trace your final desgin,pressing on it quite hard. your desgin will have transferred to you MDF. Using the scroll saw to cut out the shape from the MDF.Mark up the outside pieces. Ready for shaping on the sander.shaped an ready for pouring.Putting the three piceses togther and holding frimly. Melting the pewter.Then Mr Gundy was scraping off the oxide layer of the pewter. After Mr Gundy started pouring the pewter in the moulds.Then we have to take the cool pewter casting out of the mould. Then we have to cut off the sprue with a junior hacksaw.Then we have to drill the hole into the cast with the beach top pillar drill. After that we have to clean up the edges of the drilled hole. Using the needle files to get a great finish on the edges.Hold the work in a beach vice for areas that need more filing. Getting a good finish...Grits-180,400,1200,.. got to get that great finsh. Using a 1200 Grit with water. Then we have to wipe off the grit. Then Mr Gundy uses the buffer for a good finish. There after Mr Gundy starts to do the polishing with  Brasso for the final shine then we add a clip to make it as a neckels. I realy enjoy making the pewter casting with Mr Gundy because it shows we lots of differnt things. I have made a cross but it aint really done yet because I still have to sand paper it and then I have to polish it. But at the end of this week I would like to be up to poilshing it so then on the last week I only have to make the hole so the clip can go in it. The photo up top is what I am doing in Mr Gundys class I really enjoy it. 

Rugby

Today when the bell rang we went to line up. After that the teacher took us to the coach and his name is James. Then he made us play a game and that game is called Rats and Rabits. At first I didn't want to play because I wasn't in the mood for playing rugby.

Pewter Casting (Hard Materials)

Today we went to Tamaki college  and I was in the hard materials group and when we went in our groups we talked about materials of all different kinds and we had to fill in a doc about 4 different people that we were gonna make a necklace for it was fun knowing that we could make four different kinds of materials using medal. After we finished talking about the different material we all gathered around Mr Grundy and watched how he talked about doing silhouette it was very fun then the bell rang and we all said goodbye Mr Grundy said next week we will get to do the real thing and that would be silhouette materials. I am up to pouring the pewter into the piece of wood. After that I have to sandpaper the pewter.
