Task 1: Bowl


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 template of the base depth, then with a special mallet, begin hammering with the sharper end on the outer circles to begin creating its depth. From there it was only a matter of continuely beating the piece until it achieved the right form.



Step 3: Refinement

At this point, the piece of metal began to resemble a bowl, a bowl that didn't look like a normal bowl; bumps everywhere, overall shape didn't look so ciruclar, some edges were disproportional, and many other problems, problems that could be fixed. I also found that during the beating process that I had created a small crack on the edge, a problem that couldn't be fixed. So this step involved using the metal dome and a flat hammer to fix up some of those areas, as well as using the sand bag and mallet to go back and fix up some of the curves. The end result looked as such:



Step 5: English wheel

This was one of the final steps to smooth out the bumps and lumps around the bowl. The English wheel would be the machine to achieve this, and it looked simple enough to use, however proved to be quite the challenge in that it required a degree of technique to correctly create smooth curves. Another process that took some time to get right, it was all about assuring consistency while rolling over the bowl to create a uniform shape.



Step 6: Final Finishes

Finally it was all about finalizing everything, mainly involving sanding and polishing (which I havent gotten around doing yet). Would also go back and fix up a few bumps or inconsistencies using a cutout template.

Assignment 2 Part 2: Creating the Initial Assembly of the Car

Step 1: Assembling the Laser Cut Pieces There were many pieces that we laser cut, so it was important to organise the pieces accordingly whilst assembling them. Most pieces fitted in quite well, however there were pieces that required extra force to be properly placed in. Step 2: Adding Masking Tape Layer We decided to add a layer of masking tape over the entire model to give ourselves a better idea on the specific contours and curves of the car. It also helped with dividing the panels of the frame to be delegated to various members of our group.

Assignment 2 Part 1: Creating the Templates

Step 1: Create the files on Fusion 360 The first stage before going in and producing was to prepare the files on Fusion 360 using the Slicer software. The STL file for the Ferrario GTO 250 was imported into the program then manipulated to create the waffles that will make up the overall shape and form of the car. Step 2: Laser cutting After all the waffles and amount of slicing were sorted on Fusion 360 the next step was to begin laser cutting all the layers to be assembled using 3mm pieces of plywood.  

Task 4: Blister

This task required us to utlize CNC machined templates of teardrops to create a blister shape form using a metal sheet.  Step 1: Preparing the templates and material So the first step was to cut out the CNC templates that were given out using a jigsaw power tool (which I was unfortunately unable to take pictures of) and then smoothen the inner edges with a router power tool (which again didn't take pictures of). After that we cut out metal sheets to use for the template and the end result was as such: Step 2: Forming the shape With the material tightly secured between the two templates, it was time to then start forming the blister form shape using various mallets and cutouts to achieve the best finish. Step 3: Finishing After the intended form and shape was achieved, I decided to trim the excess material using tin snips, which were measured by etching out a cut out using a scribe. Then I began sanding out the edges using filers and san...
