Week 6: The tray was finished, the blister start





The trays had been finished in this week, my team member - Ting Ting' s and my trays can be closed together with similar edges and thickness. Using the sander to flat the four edges was the key point to match the trays together. 

The last items in this skills development process is the blister. Before the class, I looked the video - Metalshaping tricks # 5 from Youtube to achieve the general idea what to do in the class. 

Firstly, the tutors help us to create the module, two MDF boards was cut and the middle part was cut for the main shape of the blister. My team member - Ting Ting and I chose the generally round shape with a small sharp on one side. Four holes was creates for the nails to hold the metal sheet in the middle, which make the sheet not be moved during the hammer beating. 


Secondly, I started to hit the metal sheet with the eggshaped mallet, it has two different type shapes, using smooth side to hit the large area; while the needle side to hit the edges; Also lay down the hammer side to balance the entire beating area, which avoid the wave surface during the process. 


 After  a long time hitting, the depth of the shape became more clear to see, and using the different types of hammer to sharp the edges with the module. The process is: hitting in the middle, then sharp the edges, flat the entire surface, and hitting middle again.




And when I felt that the depth of the metal sheet was already enough,  I stopped to hit the metal sheet and sharp the edges with the chisel. And finally, the blister was finished!

Week 14: Finish the Ferrarri 250 GTO

Image
After 3 weeks modeling the Ferrari 250 GTO, all the metal pieces have started to place on the original board module. But Firstly, the three holes for the grille on the bonnet need to finish. At the beginning, using the module of three holes I made last week to draw the outline on the metal sheet, which this part should be careful for their location; Then it was started to drill small holes inside of the outline to create the gap for cutting the straight line; Finally, in terms of cutting just a straight line, using the jigsaw with a specific blade for metal sheet to create the line. (CAUTION: since the blade has thickness, we should to measure the location and cut inside of the outline). Eventually, I have finished all the holes and using plastic hammer with some thin timber stick to create the deep of the grilles, which just like the process of the blister.   Cutting out some extra edges for suit the original car module and group mates pieces. We started t

Week 15: tutorial for the metal blister

THE BLISTER TUTORIAL BEIL0014 – DIGITAL MAKING   Before creating the metal blister, it is strongly suggested to watch a tutorial video from the Youtube -  Metalshaping tricks # 5 , which it will help to understand the process and provide a outline for the creating steps:   Steps:  1. Creating the frame 2. Cutting the sheet 3. Shaping the deep 4. Finalising the blister Step 1 - Creating the module The based module made by MDF board should be draw and cut in following the specific outline by course tutors before the class. Two people would be a small group to create a pair of metal blister shape within two weeks, which the metal shape to be creating in the first week, and the second week should be left for adjusting with the group mate.  To creating the round shape in the middle, two tools should be carefully used into this process, which they should make the shape easy to cut and achieve smooth edge for later process - jigsaw, sander and.

Our group mates has divided the Ferrari digital model into pieces by 123dMake before the class. Then we can start to laser cutting the MDF boards for the Ferrari Pieces.  The illustrator programme print into the laser cutting programme in the lab, then set all the figures up to process the cutting. In this week, we have cutting all the pieces for the Ferrari module, which X-total 22 pieces, Y-total 18 piece for shaping the car. After that, it has been started to put into one entire module for the metal pieces shaping.
