Project 4: The Blister

Aim
The fourth project was the blister, which is metal shaping an aluminium sheet into the shape that you want to form with 2 pieces of wood of the cut out shape. Tutor/teacher has provided three materials that is necessary to do the metal shaping.
Aluminium Sheet, 2 block of wood with shape number 30, bolts 


1.

Use one of the block of wood while place the aluminium sheet on the bottom of the wood on top of a surface that is smaller than the aluminium sheet and also preferably be clamp with G-Clamps, preferably like shown on the picture


This is later to screw on on each hole to make holes on the aluminium sheet. This can be achieve by using a cordless drill.


The result of the hole-making should be like this:



2.

Later use the screw to screw the two block of wood while placing the aluminium sheet in between them aligning the screw hole. Later place the screwed the sandwich aluminium sheet on a flat surface and clamp with G-Clamp.

 
3.
Metal shaping occurs in this step. Use a melee hammer of different shape with different block of wood.




Then hit on the sandwich aluminium sheet, the pathway that was hammered as shown by the respective color. Starting from the bottom huge tear drop (red) which is easily hit using the blunt part of the melee hammer. After hitting there, around the huge tear drop, using the sharp end of the melee hammer to curve it in more to make it have more curvature and fat of the tear drop (blue) from the bottom while the top of the tear drop should be pointy and skinny (yellow). Melee hammer wont be able to hit the top part of the tear drop which means that the different block of woods needed to be use to act as a 'supporting' head which can shape the metal by using the melee hammer hitting the 'supporting' head. Warning: Try to hit the shape not that hard as it can cause crack due to lack of bottom support to absorb the impact and force of the hammer hitting. Therefore hit light but constant and know where to hit. 





Result should be like this after hitting constantly around the tear drop shape but not polished yet:



4.
After hitting constantly, this is the final result of the tear drop shape which has a finishing curvature and a nice skinny top

Reflection

Introduction This is a reflection on the work of the final assignment project, the custom tank CB550 Andrew Wallace. I will be critically reviewing it using images, video, text and drawings to reveal strengths, weaknesses and alternatives to your approach, techniques and tools. Final Project Our group consist of 7 people have chosen the custom tank CB550 Andrew Wallace. It has a unique shape from from top to bottom which has multiple curvature from both left and right side which considered on of the major challenges in this assignment. This is the final project of how our group had crated the custom tank CB550 Andrew Wallace. Strengths and Weakness There are two part of the assignment which shows both the strengths and weakness respectively of this project. The Strengths of this project would be the metal shaping while the weakness is the software usage within this project which is the Model making. Model Making - Software - Weakness This is the beginning part of th...

Project 1: The Bowl

Image
Aim The first project, 'The Bowl' which is a hemisphere 3-D shape that needs to be created starting with an aluminium sheet which has been provided by the teacher/tutor.  Procedure Pre-Procedure This pre-procedure is presented by tutors to show the students some technical steps we need to use or be prepared or will be prepared for doing project one. Laser Cutting shown by Martin Boehnel This is making four concentric rings for doing procedure one of the project which is use to make marking on the aluminium sheet to be cut and moulded, while also making a radius gauge to be use as a guide for getting the right radius. This is achieved using a laser cutter which is shown and prepared by Martin Boehnel.  Concentric Rings Radius Gauge Laser Cutter 1 Use the 4 concentric rings to make the markings on the aluminium sheet using a black or red marker These markings guides you on making the bowl by cutting and hitting it usi...

Final Project

Image
Aim The final project is to recreate a motorcycle tank from scratch from programming to metal shaping.  Procedure 1 Use  Photogrammetry  or Rhino/Grasshopper techniques to create a 3D model of your chosen fuel tank. After, u se Autodesk   Slicer   for   Fusion 360   to prepare your fuel tank template for laser cutting or CNC machining. After that, a ssemble your template. Rhino/Grasshopper techniques with  Autodesk   Slicer   for   Fusion 360 done by Russel Laser Cutting the model and putting pieces in order Assembly of the model completed version 2. It is important to be able to shape the model, a 'pattern skin' should be created for it. To be able to make the 'pattern skin', a 'skin' of the model needs to be created for the 'pattern skin' to be able to trace it. The 'pattern skin' is created using 2 A3 paper. The group has 3 team members which s...
