How to make a Torus.

Things you will need:

Aluminium Sheet

Mallet

Metal horse shoe

Metal pipe

Small metal hammer

English Wheel

Marker

Sand paper (optional)

Polisher (optional)

Step 1. Firstly with a marker, mark the middle and 2.5cm from side edges along the long side of the aluminium strip.

Step 2. Then take your aluminium strip and using the timber mould, bend the strip to make a round tin like shape. This is for the overall curvature shape of the torus.

Step 3. Once you have achieved a deep curve, align your strip so that the dip in the mold is placed on the Center line of the strip.

Step 4. Using the mallet and with consistent strength hammer down onto the Center line of strip and Work your way along its whole length to achieve consistent dips in the middle.

Step 5. Once you have achieved sufficient curve, you have the option of using an English wheel to smooth this 
Center curve

Step 6. To create the alternating curves on the sides, turn your aluminium on to its other side (back) and English wheel along the marked side lines. This will slightly flip the curves edges down, giving you an ‘m’ shaped cross section.

Step 7. Go back to hammering a deeper curve using the timber molds for the Center curve if greater curvature is desired.

Step 8. Using the metal pipe, hammer the side dips to create a more curved off edge of the torus. You can also use the metal horse shoe to work a curve at a more intricate level.

Step 9. Use a metal hammer and Mallet alternatively. Repeat for both sides along the length of the torus.

Step 10. Once desired depth of curve have been achieved using the horse shoe and timber mold, smooth out the dents with the English wheel and its roundest wheel.
