Preview division from last blog:
Individually, part one is the one i'm working on. It is basically a blister form, so we marked the top shape with paper, then make a blister template as the starting point.
Equipment involved:
Guillotine, English Wheel, Tinsnips, Metal Clamps, Round Nylon Headed Mallet, Flat Nylon Headed Mallet, Shrinker Stretcher, Sandbag, Masking tape.
Material involved:
MDF, Aluminum Sheet
several stages i have been through to make the metal skin of part one:
Blister(stage one):
Set up of the blister template
Jin and Jeremy helped me a lot by the foundation shape making. Thank you my group members they are the best!
The basic form of the shape is determined by the blister, then I hammered it on the sandbag into a bowl shape in order to further develop its shape.
found the tricky part to work on: the front part of the part one has nearly 90 degree angle curved inwards, (figure.1)
The whole blister shape curves from top the bottom, less metal involved in the bottom part. (figure.2)
figure.1
different curves in different direction
Now the shape is matching pretty well.

Free forming using the template (stage two):

Further shaping (stage three):
1. Marking the curve line,
2. keep hammering within the curving section,
3. comparing the skin with the template and mark down where to improve,
4. Trim the extra metal,
5. and keep hammer the curve.
Repeat step 2-5 again again again and again.
Special tool: (below) used the Shrinker Stretcher to make the side curved more, carefully shrink where all the major curves happened.
Polishing: (step four)
Sand the whole surface with different quality of sandpaper from rough to smooth,
Left to right: 80 sandpaper, 120 sandpaper, cleaning sponge, 240 sandpaper, 400 sandpaper, 800 sandpaper.
After sanding, i found out some lumpy part then i used english wheel to solved that problem.
Now the shape is matching pretty well.
