Reconstruction of the
North Down 10-06-2008 formation

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

2. Construct the inscribed hexagon (regular 6-sided polygon) of circle 1, pointing up.

3. Construct the inscribed circle of hexagon 2.

4. Draw the six rays of hexagon 2, from the center of circle 1 to the angular points.

5. Construct a circle centered at the intersection of the lefthand side of hexagon 2 and the horizontal centerline, passing through the intersection of circle 3 and the upper lefthand ray 4.

6. Construct a "two-points" circle, defined by the endpoints of a centerline (diameter), between the center of circle 5 and its righthand intersection with the horizontal centerline.

7. Copy circle 6 to the center of circle 1.

8. Copy circle 6 to the lefthand intersection of circle 1 and the horizontal centerline.

9. Construct a circle centered at the righthand intersection of circle 8 and the horizontal centerline, passing through the upper (and lower) lefthand angular point of hexagon 2.

10. Copy circle 9 to the intersection of circle 7 and the upper ray 4, and move it (copy and delete original) to its own intersection with the opposite ray 4.

11. Repeat step 10 another five times, with respect to the five other rays 4.

12. Copy circle 5 three times, to the upper lefthand and righthand and the lower angular points of hexagon 2.

13. Construct a circle concentric to the upper lefthand circle 12, tangent to circle 8 at the upper side.

14. Copy circle 13 five times, to the five other angular points of hexagon 2.

15. Draw the connecting line between the upper intersections of circle 10 with the upper lefthand and righthand circles 11.

16. Construct a circle concentric to circle 1, tangent to line 15.

17. Construct a circle centered at the intersection of the righthand side of hexagon 2 and the horizontal centerline, tangent to the upper righthand circle 12 at the lower side.

18. Construct a circle concentric to circle 1, tangent to circle 17 at the righthand side.

19. Construct a "two-points" circle between the intersections of the upper righthand circles 12 and 14 with the righthand side of hexagon 2.

20. Construct a circle concentric to the upper righthand circle 12, passing through the center of circle 19.

21. Copy circle 20 two times, to the centers of the two other circles 12.

22. Construct a circle centered at the righthand intersection of the upper and lower lefthand circles 11, tangent to circle 7 at the righthand side.

23. Construct a circle concentric to circle 1, passing through the righthand intersection of circle 10 and the horizontal centerline.

24. Construct the inscribed hexagon of circle 23, pointing to the right.

25. Copy circle 22 six times, to the intersections of the six rays 4 and the six sides of hexagon 24.

26. Construct a (small) "two-points" circle, between the center of circle 22 and its righthand intersection with the horizontal centerline.

27. Construct a circle concentric to circle 1, passing through the upper intersection of the upper lefthand and righthand circles 11.

28. Construct the inscribed hexagon of circle 27, pointing to the right.

29. Copy circle 26 six times, to the six angular points of hexagon 28.

30. Circles 1, 7, 10, 11, 12, 13, 14, 16, 18, 20, 21, 25 and 29 are used for the final reconstruction.

31. Remove all unnecessary parts, not visible in the formation itself.
