Mr. Bosch and the Windmill Tower
resting in its winding jig. This beam was made totally by hand. (24k) |

Pouring the foundation. A special
metal plate with custom hinges was embedded in the foundation. This allowed the tower to
be mounted while in a horizontal position. (34k) |

The windmill mount on the top of
the tower. (21k) |

The Captive Column getting
mounted to its base. After attaching it to the hinge, the tower was pivoted to a vertical
position. After being raised, the base plate mounted to the bottom of the Captive Column
was bolted to the foundation. The holes in the corners of the base plate were for this
purpose. (23k) |

Raising the tower. This Captive
Column was heavier than most (less than 1,000 pounds), so a small crane was needed. Low
quality 1-inch diameter steel columns (rebar) and a heavier core (pine) contributed to the
weight. The tower could be lowered in a similar fashion to facilitate maintenance of the
windmill. (16k) |
