Move another two lines to the right, and repeat with a pin from a third pair of pins. |

Move another two lines to the right, and repeat with a pin from a third pair of pins. |
 |
Repeat through each of the remaining first pins of each pair. You will have five different colored pins on alternate lines around the ball the measured distance from the north pole, and five pins remaining on the alternate lines at the obi points. |
 |
You will now repeat the process around the opposite pole. Choose
a line and locate the matching pin - in this case, pink. With the south
pole facing you, measure the 1/3+1/100th from the pole on the same line
as the matching pin and place the mate to the pair. The pair of pins will
be diametrically opposite each other (you can hold the ball by the pin
pair and they are now poles).
Remove the obi pin from that line. |
 |
Move two lines to the right, choose the matching pin - here is is purple, and insert it the measured distance from the south pole. Again, the two partners of this pin pair will be opposite each other. Remember that you can right-click and enlarge (select view image from the context menu) to see a larger version of any image. |

Continue around the rest of the pairs placing the remaining partners
to the pairs the measured distance from the pole. When you are finished,
each pair will be opposite each other - notice the pink and the green pair
in this photo - each pin of the pair is across the ball from the mate.
Now, to check how things are going, use the 1/3+1/100th distance strip,
and check the distance between any two pins - the colored pairs and the
north and south poles - the distance between any two pins is (or should
be) that 1/3+1/100th distance.
if not, recheck the measurements, pin placements, and roundness of the ball. If slight adjustments bring things into line, fine. If not, and that distance is off between pins, you will not finish with an even divide of 12 equal and centered pentagons. |
 |
Now to begin wrapping the threads, choose any pin to start at, measure off four wraps around the ball plus a little. Anchor the thread at the pin you have chosen to being at - here is it pink. You can think of each pin pair now becoming a north and south pole, and the remaining pins are the targets you are going to wrap to to get ten spokes coming from each pin. |
