Arrived at the top... Pulleys mounted and equipped with rope. Ropes for bracing the mast are already placed. |

First lifting test of the boom was successful! However, it turned out that the rope unfortunately stretched way to much. Later I will replace it against a steel cable. Furthermore, an additional brace on the connector was required. |

The first holes for the foundation posts are excavated. At 2 1/2 to 3 ft depth I discovered solid rock and have therefore decided to dig by hand. |

The initial suspicion had been confirmed. All excavations ended in bedrock. The last remains of soil however, I had to eliminate from the hole with a small garden shovel. The deepest point goes down to 3 ft 4 in. |

Before I could begin to manufacture the concrete posts, that mighty boulder had to be cleared out of the way. Diameter 3 ft 5 in! Levered it out of the hole with these three thick branches. |

The most of my big tools I had available was at the start here. Ultimately, a weld broke on the come-a-long as the stone was almost out of the way. |

Mixing cement for the foundation posts. Water from the lake, premix concrete from the hardware store and power of my upper arms! |

Bottom of the hole covered with concrete and the elongated sono tubes (Ø 10 inch) set in, fixed and filled it up to the edge. Rebars inserted and aligned centrally. A bag of premix (66 lb) gave approximately 8 inch in height. In the end I needed 74 bags or 4894 lb of concrete. |
