How to make a sheet metal cone.

The easiest way to make a cone is to start with a semicircle then overlap the straight edges until they form a cone shape. Here is one way to make a cone from flat stock. The most suitable bending method depends on the material plate thickness and the circumference of the small diameter. You can find cone calculators online.

Plate rolling is the process in which a cone template is being rolled into the required conical shape by moving it through a three or four roller bending machine. The formula for the cone is first you must find the difference between the large and the small dia. By the vertical height divide this product by the difference first obtained large dia and small dia. Roll the cone template into a cone shape starting at the wide end working toward the pivot point end.

If you want to get more specific however you should start with a circle instead then cut a wedge out. The flat cone templates can be bent either by rolling the plate with a three roller bending machine or by press braking on a power press. It allows you to determine either the size of raw material needed or the number of gore sections to fit on your available material. View the cone instructions below to learn how to manually layout the flat pattern for a truncated cone in single or multiple gore sections.

I used aluminum sheet coil but you could use paper or any flat material. The cone has a diameter at the top smaller than the diameter at the bottom and to accurately trace the shape onto sheet metal you need to make a template out of construction paper.

Once you know how to make a basic cone you can experiment with other materials such as plastic sheeting. Both methods will be explained below.
