Steel plate is formed into cones primarily by either rolling the plate in a plate roll or forming the plate with radius dies in a press brake.
How to roll a sheet metal cone.
View the cone instructions below to learn how to manually layout the flat pattern for a truncated cone in single or multiple gore sections.
How to roll a metal cone step 1.
Sheet metal cone calculator.
To demonstrate the correct method of setting up pinch rolls.
The pencil will make the circle and the slight indentation where the compass has.
The string should be.
Multiply the large dia.
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.
Cones can be produced from a single piece of steel or in segments.
Cut this circle out with your sheet metal shears.
Wear gloves for this since the edges of the metal can.
Cut a length of string with a loop at one end and the other end held at the pivot mark.
It allows you to determine either the size of raw material needed or the number of gore sections to fit on your available material.
By the vertical height divide this product by the difference first obtained large dia and small dia this will give you the length of the center line you need from the top of the cone to the intersecting point a large dia small dia 20 8 12.

Draw a circle on the sheet metal with a pencil compass.
