Two toroid halves from Hobby craft, each 170mm in diameter. The two halves are taped together with electrical tape. |
 |
Using strips of aluminum foil we cover the outside of the toroid. |
 |
Taking two CDs one on the top and one on the bottom |
 |
We cover the CDs and attach them to the torroid with more of the aluminum tape to make a top and bottom. |
 |
After covering all of the torrid, top and bottom. Use your fingernail to smooth out the creases in the aluminum. Don’t press too hard as you will deform the polystyrene. |
