Aluminium Bowl

Aluminium Bowl making
Aim: 
Make a smooth bowl with accurate radium according to the class instructions.

Objectives:
  1. Completed bowl is line with the chosen radian by Russel.
  2. The surface is smooth and even.
  3. It has a flat and smooth edge.
Equipments and tools:
  • Concentric circles
  • Tin snip
  • Shear
  • File
  • Sand paper
  • Mallet
  • Timber stump
  • English wheel
  • Sand bag
  • Hammer (plain head)
How we work:
  1. Use the concentric circles to mark the circle lines on the metal sheet. Those different size of circle will guide how to make the bowl.
  2. Use Tin snip to cut the area outside the outer circle. Use scissors to remove the burs and make the edges smooth.
  3. Put the aluminium sheet on a timber stump, which has a curved bottom. And keep hammering it from outer circle to the inner by fibreglass mallet. The intensity of each hit should be controlled evenly.
  4. Use the English wheel to remove and smooth the dents on the bowl's surface. Also, it can make the bowl has a evenly radium curving.
  5. Use sand paper to polish the bowl.

Assignment 2: The Fuel Tank

Image
Aim: Form a group of 10 students who are from different disciplines to make a 1:1 scale model of custom tank for a CB550. Our group will be divided into three groups to make three fuel tanks, and each student is responsible for one side of the fuel tank. We need to shape the aluminium shape to create a fuel tank. Objectives: completed a model, which choose from the three options of fuel tanks. The surface must be smooth and even. The aluminium fuel tank has a flat and smooth edge. the seperate parts of fuel tank must be fit to other two sides. record the process of fabricating the fuel tank. Equipments and tools: Sand bag File Hammers Tin snips Guillotine English wheel Construction steps: Moel construction Firstly, we need to use photogrammetry to fabricate a 1:1 model of fuel tank so that it would be easy to shape the aluminium sheet according to this model. For this 3D model, we need to use revit. For next step, we need to export the model

Personal Reflection

Fuel Tank The project I’ve chosen to do the reflection is the fuel tank because this project costed me the longest time to complete it among other projects. In the process of making the fuel tank, I failed three times because of the accidental edge crack. First of all, lets discuss the weaknesses of this project. In the process of shaping the aluminium sheet, we need to change its radian from two different directions (horizontal, vertical). And it is very easy to break in the edge because of the hard hammering. The tear would be bigger and bigger if we didn’t give up the work. As we mentioned above, we need to change its radian in two directions. The aluminium sheet is soft and easy to be shaped comparing with other metals so it is also easy to deform. For example, when the horizontal radian fits the model shape, then we try to change the vertical radian. The whole aluminium plate will change the shape because of hitting force. This problem is such a big test of our patience. Second
