BEIL0014 - Digital Making

Getting the Secondary curve To achieve this curve I decided to use the stretcher machine, and just by the results I wasn't able to achieve it without a cracking point. It was quite difficult as it needed precise pressure on the step. 2nd Attempt So I decided to approach it another way - by manual brute force with the mallets and the curve template.   This process proved to be more effective as it gave me better control over the material, however it meant that it was a quite a longer process to achieve the curve, as well as that it was more difficult to get a cleaner and smoother finish.

What I've done so far: Step 1: Cutting the work piece Step 2: Getting the initial curve There were actually a number of ways to achieve this, my first approach was to use the metal roller:

The first task we were given to do was to implement various workshop processes to create a bowl-shaped form out of a 2 mm sheet of metal.  Step 1: Cutting out the material The initial stages proved to be quite tedious as it involved measuring out dimensions and cutting out the appropriate shape to begin working with. This involved whipping out a protractor to etch the template for the overall base of the bowl. Then with the use of a pruner, we were able to cut out the shape, which actually proved to be quite harder than it looked. To finish off, some sanding was done on the edges to get a more precise cut finish. Step 2: Initial metal beating Now it was time to get into the interesting part, beating the crap out of the material until it provided a form that would somewhat resemble the shape of a bowl. Before any of that happened, it is important that inner circles were drawn out to give visual representation on what areas to hammer down. Next was to grab a wooden templat...
