The Blister - The Making
1. Obtain material and template
The material was collected as per usual, divided in to 4 pieces and trimmed with the guillotine
The templates were collected in identical pairs. These templates were then processed by removing splinters and sanded down creating a "tear drop" cut out to be clamped with the aluminium sheet.
2. Hammering "sandwiched" work piece (FAILED)
The workpiece was placed in between the 2 templates screwed on tightly ensuring work-piece to not move when hammered.
Using wooden blocks rounded at the tip on disc sander, the work-piece was hammered from the side down to the middle
then towards the tip of the "tear drop", the work-piece cracked due to increased pressure created by the sharpened wooden block beated continuously
3. Failed result
The outcome was a failed result, thus a new piece was made
5. Hammering "sandwiched" work piece (FINAL)
New tools were used and after some explanations and advice, the work piece was hammered using the back of the nylon mallet.
The hammering process was done in reverse this time, from middle to the edge then to the tip.
Cautions were taken while at the tip to not overly beat it creating cracks. the results as compared to the failed work-piece was significantly better in quality as shown below:

The Tray - The Making
1. Collecting and cutting material to size
The sheet of aluminium was divided evenly to 2 for 2 pairs, (2 couples).
It is then divided EVENLY to another 2, for each person in the pair.
Due to the fact that it was divided evenly with equal dimensions, we both will start with aluminium sheets identical in dimensions.
2. Marking and creating the wooden templates
10mm offset was agreed by both as the guide to fold the work-piece and is marked by a sharp object.
Thereafter, a pair of wooden cylindrical wooden templates are produced with 50mm in diameter and is marked from tangents of the 10mm offset.
This concludes the setup for the tray ensuring both of us has the same setup.
3. Folding the 4 edges
The work piece was clamped down by 2 wooden blocks exposing only the 10mm offset.
It is then hammered using a metal hammer on all 4 corners.
4. Folding the corners
After folding the edges, the 4 corners are folded and stretched with the 50mm diameter wooden template hammering it left to right evenly to ensure stretching to occur only at the middle of the corner. Care was taken not to ripple by prioritising stretching of folded aluminium due to stretching to 1 side.
5. Trimming the stretched corners
The stretched corners were then trim to align with the 10mm edges
6. Pairing and ajusting
The paired work piece were put together and further adjustments were made to ensure they both match
