BEIL0014 Aluminium bowl making
BEIL 0014 Digital Making
The first project is to create a aluminium bowl by hammering and cutting. At first we were given a aluminium sheet and cut it into a circle by using series of concentric rings to draw a perfect circles on the aluminium sheet. The larger ring helps shapes the metal sheet into a circle, smaller ring helps creating a guides for hammering.
A female radius gauge helps evaluate and monitor the progress of making the metal bowl by using the concave curve on the gauge. It provides 3 different curves to choose from, in this case, i chose r125 in the beginning of the bowl, but when the hammering process proceed, shrinking and stretching occurs, it is very difficult to control the curve of the bowl, especially using the sand bag as the base of the hammering process. I end up with r155 by using the english wheel.
The english wheel is the final step to take the bowl into a relatively round shape, it works as a linear hammer and by choosing the correct wheel, this step can help squeezing the metal sheet and draw the better curve on the bowl. Using the english wheel is easier to manage and control than hammering the bowl for the designated curves.

Hammering the inner circle of the metal, the outside edge will pops up creating v shape, the edge will fold eventually if i keep on hammering the middle, therefore the edge needed to be treat as soon as possible prevent it folding and making irretracable result by ruining the edges.
Using sand bag allows the bowl to go further down the sand bag, giving it space to be drawn downward.
By using the planishing hammer, the edges are smoothen.
At this point, the bowl is not fitted to the female radius gauge of r155, further adjustment by the english wheel is essential.
After using the english wheel, the final product finally meets the criteria of r155 of the radius gauge.
