Hey guys,
I'm looking for literature for making a ball... Not one with parts running horizontal like bands.
The ball I need to make has just one pattern for all 24 pieces... They run from pole to pole, kinda like peel on an orange wedge.
I've found two books on the horizontal band method and one for forming s copper float ball out of two pieces, but nothing for what I'm after.
The layout seems simple enough to me...
1. Multiply the dia. by pi to get the circumference and divide that by 24 to get the widest part of the pattern, like at the equator.
2. Divide the circumference by 2 to get the stretch out for pole to pole.
3. Add for seams and cut out 24 identical pieces.
I can also determine the diameter at given horizontal postions and repete step one to "fair" my curve at the pattern's edge.
I'm sure I'm probably leaving an important step out too...
Any body know of any articles that show the layout process for a sphere in this manner? |

Never mind...
I found it in the Library...
The Metal Worker Pattern Book (1881)
By A.O.Kettridge
Part 5
Looks very easy to layout, but appears to be a mutha to fabricate.  |
