Reconstruction of theBarbury Castle 14-06-2020 formation | |||||

1. |
Draw a circle. Draw and extend the horizontal and vertical centerlines. | ||||

2. |
Construct the circumscribed dodecagon (regular 12-sided polygon) of circle 1, with the mid-point of one side coincident with the upper intersection of circle 1 and the vertical centerline. | ||||

3. |
Construct the circumscribed circle of dodecagon 2. | ||||

4. |
Construct a circle centered at the upper intersection of circle 1 and the vertical centerline, passing through the righthand angular point of dodecagon 2 adjacent to the top. | ||||

5. |
Copy circle 4 to the center of circle 1. | ||||

6. |
Construct a circle concentric to circle 4, tangent to circle 3 at the upper side. | ||||

7. |
Copy circle 6 to the upper intersection of circle 5 and the vertical centerline. | ||||

8. |
Construct a circle concentric to circle 1, tangent to circle 7 at the upper side. | ||||

9. |
Copy circle 6 to the upper intersection of circle 8 and the vertical centerline. | ||||

10. |
Construct a circle concentric to circle 1, tangent to circle 9 at the upper side. | ||||

11. |
Construct a circle concentric to circle 4, tangent to circle 10 at the upper side. | ||||

12. |
Construct the inscribed dodecagon of circle 1, pointing up. | ||||

13. |
Copy circle 11 eleven times, to the other angular points of dodecagon 12. | ||||

14. |
Construct the circumscribed hexagon (regular 6-sided polygon) of circle 1, pointing to the right. | ||||

15. |
Construct the circumscribed circle of hexagon 14. | ||||

16. |
Copy circle 6 to the upper intersection of circle 15 and the vertical centerline. | ||||

17. |
Construct a circle concentric to circle 1, tangent to circle 16 at the lower side. | ||||

18. |
Circles 1, 3, 5, 8, 11, 13, 15, and 17, are used for the final reconstruction. | ||||
