Construct a circle of the desired diameter and draw concentric circles within it to subdivide it into ten rings of equal width. If R is the radius of the net, the radius of the nth ring from the center is rn = nR/10. Also divide the figure into 60-degree sectors as shown. |

For the highest possible accuracy, divide the nth ring in each sector into n equal arcs. The angles a will be given by an = 60i/n, where i ranges from 1 to 6n. The second ring out is divided at 30 degree intervals (60/2), the third at 20 degree intervals (60/3), and so on. However, a tolerably good construction is to bisect each sector (light blue lines). From each even numbered ring construct lines parallel to the sector boundaries (red lines). |
