How Do I Make A Cone Out Of Sheet Metal

Drill a few holes through the overlapping rectangular shape.

How do i make a cone out of sheet metal. Beginning at the cut push the pieces of sheet over each other. Overlap one cut side onto the other. It allows you to determine either the size of raw material needed or the number of gore sections to fit on your available material. Sheet metal cone calculator.

As you do this you will see the circle begin to contract into a cone. Roll the cone template into a cone shape starting at the wide end working toward the pivot point end. View the cone instructions below to learn how to manually layout the flat pattern for a truncated cone in single or multiple gore sections. 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.

Cut out the cone template from your sheet metal using tin snips and file the edges smooth of any burrs of rough sections with your file. Using my sheet metal open sketch technique we can draw an arc and its construction lines. With the radius or diameter dimension plus a dimension for the gap we can exit this sketch and move onto the next profile. Step 5 roll the template into a cone shape overlapping the sheet metal by 1 2 inch then drill a few holes along the seam and seal it closed by placing rivets in the drilled holes.

I typically like to start my first sketch on the top plane.
