Reconstruction of the
Woodborough Hill 10-08-2009 formation
1. Draw a circle. Draw and extend the horizontal and vertical centerlines.
2. Copy circle 1 to its righthand intersection with the horizontal centerline. Move this circle (copy and delete original) to its own corresponding intersection.
3. Copy circle 1 to the righthand intersection of circle 2 and the horizontal centerline.
4. Copy circle 1 to the righthand intersection of circle 3 and the horizontal centerline.
5. Construct a circle concentric to circle 4, tangent to circle 1 at the righthand side.
6. Construct a "two-points" circle (defined by the end-points of a centerline) between the righthand intersection of circle 5 and the lefthand intersection of circle 1, both with the horizontal centerline.
7. Copy circles 4, 5 and 6 as a whole, while mirroring with respect to the vertical centerline.
8. Remove from circles 1, 4, 5, 6 and 7, all parts not visible within the formation itself.
9. Copy circle 5 to its righthand intersection with the horizontal centerline, and move it to its own corresponding intersection.
10. Construct a circle concentric to circle 1, tangent to circle 9 at the righthand side.
11. Copy circle 1 to the righthand intersection of circle 10 and the horizontal centerline.
12. Construct a "two-points" circle between the intersections of circle 6 and its copied circle 7.
13. Construct a "two-points" circle between the lefthand intersection of circle 3 and the righthand intersection of circle 12, both with the horizontal centerline.
14. Copy circle 13 to the righthand intersection of circle 11 and the horizontal centerline.
15. Construct a circle concentric to circle 1, tangent to circle 14 at the lefthand side.
16. Copy circle 13 two times, to the intersections of circle 15 and the vertical centerline.
17. Copy circle 1 two times, one to the lefthand intersection of the upper circle 16, and one to the righthand intersection of the lower circle 16, both with circle 15.
18. Construct the inscribed nonagon (regular 9-sided polygon) of circle 15, with one angular point coincident with the lefthand intersection of upper circle 17 and circle 15.
19. Construct the inscribed nonagon of circle 15, with one angular point coincident with the righthand intersection of upper circle 17 and circle 15.
20. Construct the inscribed nonagon of circle 15, with one angular point coincident with the lefthand intersection of lower circle 17 and circle 15.
21. Construct the inscribed nonagon of circle 15, with one angular point coincident with the righthand intersection of lower circle 17 and circle 15.
22. Construct nine "two-points" circles, between each pair of adjacent angular points of nonagon 18.
23. Construct nine "two-points" circles, between each pair of adjacent angular points of nonagon 19.
24. Construct nine "two-points" circles, between each pair of adjacent angular points of nonagon 20.
25. Construct nine "two-points" circles, between each pair of adjacent angular points of nonagon 21.
26. Remove from circles 22, 23, 24 and 25, all parts not visible within the formation itself.
27. Copy circle 13 to the righthand intersection of circle 10 and the horizontal centerline.
28. Construct two circles concentric to circle 1, tangent to circle 27 at both sides.
29. Construct a circle concentric to circle 1, passing through the rightmost intersection of pattern 8 and the horizontal centerline.
30. Construct the inscribed nonagon of circle 29, pointing to the left.
31. Construct a "two-points" circle between the righthand intersection of circle 29 and the intersection of the righthand side of nonagon 30, both with the horizontal centerline.
32. Construct a "two-points" circle between the center of circle 31 and its righthand intersection with the horizontal centerline.
33. Copy circle 13 to the righthand intersection of circle 29 and the horizontal centerline, and move it to its own corresponding intersection.
34. Copy circle 32 to the righthand intersection of circle 33 and the horizontal centerline.
35. Construct two circles concentric to circle 1, tangent to circle 34 at both sides.
36. Copy circle 1 four times, to the intersections of circle 15 and the horizontal and vertical centerlines.
37. Draw eight rays, from the center of circle 1 to the intersections of circles 36 and circle 15.
38. Divide the four larger arcs of circle 29 in between rays 37 each into seven equal parts, as shown.
39. Draw twenty-four rays, from the center of circle 1 to the division-points of arcs 38.
40. Construct thirty-two circles, tangent to each pair of adjacent rays 37 and 39, and tangent to circle 29 inwardly, as shown (with some examples).
41. Remove from pattern 8, circles 29 and 40, and rays 37 and 39, all parts not visible within the formation itself.
42. Patterns 26 and 41, and circles 10, 28 and 35, together make up the final reconstruction.
