Template for Standard Cloudbuster
The following image was created by Don Croft to describe the construction of the three wood templates required for a cloudbuster.
Make three copies, one for each size wood template.

TEMPLATE MAKING USING COMPASS:
 |
Use Compass to get radius of bucket bottom |
 |
Using that radius, draw circle on wood, then place pipe inside circle to get radius of pipe circle |
 |
Draw circle |
 |
Then, using same radius, draw circle for top template. |
 |
[To get the 6 pipe positions] Using same radius put compass point anywhere on circle and draw a curve to cut the circle either side. |
 |
Then move around circle doing the same. Strangely enough, you then get 6 points on the circle, which must be why the CB works best with 6 pipes. |
 |
|
 |
6 points on bottom template. Do the same for top template. Then draw circle around centre of bottom template--you then cut that out, and also cut away more wood between the pipe holes----see drawing above. |
 |
After finding 6 pipe positions (not shown here),
put pipe on top circle to get radius for outside of top template. Draw circle |
Below is the method explained again (for a hexagon in this case):
Picking any point on the circle as the center, draw another circle
of the same radius. From the two points of intersection, draw circles
and
.
Finally, draw
centered on the intersection of circles
and
.
The six circle-circle intersections then determine the vertices of a regular
hexagon.
