Above: 1. Start with a length of 30-34 gauge metal, roll through the Bonny Doon Microfold Brake (inset) |
| |

2. Place the annealed piece on a wooden or delrin 1/2 round channel |
| |

3. Use a pipe or round mandrel to form the corrugated piece down into the 1/2 round channel |
| |

4. Start wrapping the annealed 1/2 round channel of metal by pinching the ends as shown above, do not pinch the end corrugations |
| |

Note that the last corrugation is not pinched, this allows it to mate with the opposite end |
| |

5. Overlap the two end corrugations, pinch with some small pliers to secure. |
| |

A little light hammering with a plastic mallet trues up the sphere |
