Stage A: We are going to form a group of 10 and create a template first.The fuel tank we choose is Custom tank for a CB550: Andrew Wallace, which has a multiplication factor.
Stage B: Dividing the part of model. In this stage, we are going to divide the model to 3 part. My group was interdisciplinary and consisted of : Wang Yaoxuan , Liu Xiaoyu , Wang Ziqing , Wu Yuqing .

The piece I chose to complete this assessment was the top part of the fuel tank.
The first step with my group was to import a 3D model of the Guel Tank into the computer program Slicer, We were then able to convert the 3D model into a waffle template that could be assembled. And we carefully adjusted the settings to our preferences which included, type of material, the thickness of material and number of waffle panels on the x and y-axis.
The parameter for the model was set at 10 waffles down the body and 15 waffles across using 3mm MDF. we assembled the parts together, and used a soft melee to gently hammer the pieces together.After all the segments were laser cut, the delicate procedure begun of putting the model together.
The next step was to use the templates we made to create the general shape of the metal sheets, use paper tape to wrap the whole shape for better sight of curvature and detail. This process involved using scribes to create the shape that will be cut out using the cutting shears. we decided it is beast to create templates out of tracing paper to get the most accurate end result as possible.
Ensure the paper templates is large enough for stretching and shrinking of metal as the forming would be undertaken.

Technique:
Create a wooden 'buck' that can be assembled to be used as a guide, this will allow for more accurate moulding of the skin as well as making it easier to create the curve of top form.
I marked out the the deepest point and areas and hammer the marked area to get an initial shape.
After I bent the shape of the parts using the wooden bock, I began creating the initial curves using a hammer and a sandbag. it was just constant reshaping and tampering with the piece until I got the desired result. and using the metal dome templates to beat out specific shapes.
Technique:
Using the nylon hammer to curve edges down flush with the template , and make sure the template can withstand the force of the mallet hitting.
After hammer the whole piece and use the English wheel to make the sheet become more flat and overall fit the waffles model. Follow the long curve of the tank and ensure both sides of the roller adjusted evenly, Adjust the angle of the roller and repeat this step until the curvature of your part matches the part of the template.
The top curvature can be create by using the vice with a mould , vice with the anvil can mitigate any potential movement of metal whilst maintaining its shape.
Starting to mark holes on the piece and use Jigsaw to cut it out.
Use the file and sanders to smooth the edges of blister.

Final result
All the pieces fit in the model.with other group members.
