Two years ago I posted an inquiry for ideas about how best to form a double curved cone.

We use these in elevated water tanks for municipalities for their drinking water supply.

The cone is a smooth or flared transition between the stem of the tank and the sphere. The tank is similar to a golf ball on a tee. It is known as a water sphere type tank. The flared cone goes between the shaft or stem of the tank and the sphere on top.
