Mark your diameter, start from the centre of the circle and mark the length of the mould you are making, mark the height of the mould. You will have two circles, the diameter of the sphere and the width of the mould less the outside edge.

The two lines from the centre to the points on the outside circumference (the width of you brick or adobe) mark the sides of your mould. The front of your mould is the inside curvature of the circumference. The back of the mould has an inverse curvature as it represents the inside face.

The smaller the sphere the more important the mould. We found that in a sphere that has a circumference of 6 metres the angles are small enough regularly available rectangular building materials can be used. The integrity of the sphere is maintained by the guiding stick (photo) and adjusted by the masonry work.

For our 6 metre project of an acoustic shell we had bricks moulded and fired that were 30 cm long, 11 cm wide and 9 cm tall. Regular bricks could have been used.

You can get a appox. idea of the nu. of bricks you need by dividing the area of the sphere by the area of a single brick.

What I believe to be original in my technique is the simplicity with which it works a sphere.It is the means by which a mould is made that would hold clay or adobe in a size in which one fits all. That is to say it is a way of dividing up a sphere into pieces of equal size. When I looked up the question in Google, the only answer I found was astrophysicist who was interested in creating a grid filter with which to look at the universe. However, we didn’t speak the same language. His mathematical formulas were gibberish to the fine mind I have in my behind.

My first thought was to call on the help of a friend that reads math. I was in the middle of redacting the letter when the solution came to me. “Look out from the centre of the sphere.”

So then, you project your dimensions on that screen and make your moulds with the angles curves and measurements that you come up with drawing on the inside surface of the sphere.

My son-in-law says that I create simple techniques that can create complicated objects. In this case, the answer is so simple, that I wonder, am the only that missed it. Or maybe nobody was asking the question.

There are many ways to build a spherical building. This technique is dedicated to a simple inexpensive way for poor people who need to build a home safe from earthquakes and hurricanes. For anyone who needs to build a spherical structure for THEIR OWN needs, they can use this tool for free.

Those who want to use it for commercial purposes, I would be happy to partner in the dispersion of this technique to world.

We can come to a sum.
