Week 3 - Making a Reverse Curve

week3 - The Torus

I have tried two different ways to make this project.

Prepared work

Firstly draw the line to separate the different sections of the curvature.

Option 1. Shrinking the center strip first

Using the mallet to create a depression carved into the radius of a stump to shrink the center.

Tip is to find a responsible person will be very helpful to hold the aluminum sheet and get the initial curve. Otherwise, put a sandbag under the stump to stop it rolling.

Next step is placed the edges on the shrining dolly, used the hammer to stretch out the both edges to create reverse curves.

Option 2. Stretching the outside edges first

Using the stretch machine to crimp the two side of the aluminum sheet.

Then using the steel mallet to shrink the center curve. Used the English wheel and the dolly to fixed the surface when you are not satisfied.

Finished!!
