Reconstruction of theChirton Bottom 5-09-2020 formation | |||||

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

2. |
Copy circle 1 to its upper intersection with the vertical centerline. | ||||

3. |
Copy circle 1 to its lower intersection with the vertical centerline. | ||||

4. |
Construct a circle concentric to circle 1, tangent to circle 2 at the upper side. | ||||

5. |
Construct the inscribed regular 15-sided polygon of circle 4, pointing up. Number the angular points clockwise 1 - 15, starting at the top. | ||||

6. |
Draw the connecting line between angular points 5 nrs. 2 and 15. | ||||

7. |
Construct a circle concentric to circle 1, tangent to line 6. | ||||

8. |
Construct a "two-points" circle (defined by the two end-points of a centerline) between the upper intersections of circles 4 and 7 with the vertical centerline. | ||||

9. |
Copy circle 8 to the upper intersection of circle 1 and the vertical centerline. | ||||

10. |
Construct a line parallel to the horizontal centerline, tangent to circle 9 at the upper side, and extend this line upto circle 7 in both directions. | ||||

11. |
Construct a line parallel to the horizontal centerline, tangent to circle 9 at the lower side, and extend this line upto circle 7 in both directions. | ||||

12. |
Construct a line parallel to the horizontal centerline, tangent to circle 1 at the lower side, and extend this line upto circle 7 in both directions. | ||||

13. |
Copy circle 8 to the lower intersection of circle 1 and the vertical centerline, and move this circle (copy and delete original) to its own corresponding intersection. | ||||

14. |
Construct a line parallel to the horizontal centerline, tangent to circle 13 at the lower side, and extend this line upto circle 7 in both directions. | ||||

15. |
Construct a line parallel to the horizontal centerline, passing through the center of circle 9, and extend this line upto circle 7 in both directions. | ||||

16. |
Draw the ray of polygon 5 from the center to angular point nr. 15. | ||||

17. |
Draw the connecting line between angular points 5 nrs. 5 and 12. | ||||

18. |
Draw the ray of polygon 5 from the center to angular point nr. 7. | ||||

19. |
Draw the connecting line between the intersection of line 15 and ray 16, and the intersection of line 17 and ray 18, and extend this line upto circle 4 in both directions. | ||||

20. |
Circles 4 and 7, and lines 10, 11, 12, 14, and 19, are used for the final reconstruction. | ||||
