The last couple of days, we made some headway. We prepared the foundation by levelling the flat bars which now form a perimeter around the base of the dome. We used a levelling tube. This needs two people...one person to hold the point of reference in place and the other to mark each stake around the circumference of the dome. Then it's time to adjust the flatbars and pin them to the marked stakes using a vise grip. The next step will be to pour the foundation. this will take a few days and I am not sure yet whether or not we will fit it into this visit.
