Project 2: The Torus

Aim
The second project, 'The Torus' which is a three-dimensional version of a circle or doughnut shape. An aluminium sheet has been given to make 1/4 of the Torus which is also known as the reverse curve. 

1.
Mark the aluminium sheet with a red or black marker to make guidelines when hitting on the sheet as shown below. Placing it like below, the marking is having a 3cm line from the top and bottom while having 5 vertical line evenly spread throughout the aluminium.

2.
Placing the marked aluminium sheet on the stump with a eye shape and bend it until its curved that is warping on the stump as shown below.

Bending the aluminium on the stump


3.
Hold the aluminium in place with the stump, this can be achieve with a friend holding side to side of the aluminium sheet on the stump or using a G-clamp. Then using a melee hammer to hit left and right close of the middle line of the aluminium sheet using the sharp side on the left and right gap while blunt side on the middle line. But when hitting, try not to go over the second and third line of the aluminium sheet.
Melee Hammer

Sharp and Blunt side on where to hit

Result after a lot of shrinking
Tip: When doing this, try not to move the aluminium out of the stump eye deep a lot cause the aluminium doesn't like to cross over fold or crease around the edge, therefore hold in place as much as possible.

4.
After the shrinking the centre strip, do the shrinking for the outside edge done by the anvil hit with the planishing hammer, where it should not shrink over the second line of your aluminium sheet and the tip of the torus should be where the marking of the first line should be.

Half result: Left is done with planishing hammer, right is not

Result


4.5
To make have a nicer texture, sanding with a sand paper can be achieved but can use the English Wheel using the most curved wheel only on the middle line area to give a bit of a curvature because using the other type will flatten the depth of the torus causing it to go back being a aluminium sheet. Therefore don't use the other wheel other than most curved wheel
Sandpaper

5.
After a lot of sanding and a bit of English wheeling, this is the result.

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...
