Setting the Anchor

Andrew wanted to set the anchor in the top of the dome. The anchor has an eye on both ends to make dome maintenance easier. On Wednesday, Andrew and Zachary climbed up the dome to drill a pilot hole through the foam and concrete. Michael was the ground crew, tying needed equipment on the rope. After Andrew had drilled the hole from the top, he had to drill from the inside. This required several trips up and down the dome.

After Andrew inserted the bolt, Michael tightened it from inside of the dome. While Andrew and Zachary tightened it from the the top of the dome.

Job well done, boys!
