The dimensions that define a given cone include the minor diameter, the major diameter, the height of the cone, and, of course, the thickness of the 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. You will need an overlap area to soilder or rivet it. If you want to make a paper cone, cut out a semi-circle and fold it over on itself to get your desired cone width.

They start with a flat piece of steel(or stainless),they make the lines and put it thru the break,it might take three or four sheets to make a complete cone, then they weld it together. They are two of 24each 180 degree cone segments which when welded into full cylinders and then welded end to end will form two tapered smokestacks more than 50ft high. Also check out Joanns fabrics and also the craft stores. This cone is fairly difficult to make because of the extreme difference in the major and minor diameters over a short distance. Project the. Sounds to me you are on track. Then trace it out and cut. These are just a few examples of how steel plate can be formed into cones from one-piece to two-piece to twelve-piece construction. Adjust tip of the cone to be a point. (I consider it a success so far because I worked with sheet metal including several minutes worth of cutting with tin snips and haven't drawn blood yet.).

Select output Fraction Precision, Decimal Inch or Metric mm. Rolling such large pieces reduces the number of welds that smaller sections would have required to make the assembly. Each of the cones in the pictures below is made from four pieces of 3/16 mild steel. Locate a radius point Example if CR = 11 R = 10 11 - 10 = 1 multiply answer times pi (3.1416) 1 X 3.1416 = 3.1416 inches to cut out of circle. To make a solid cone, trace the bottom of the cone onto a spare sheet of material, then cut the circle out. from the base to the apex of the cone. Cut this circle out with your sheet metal shears. 9.

Keep rotating and pressing the cone until the entire hem is ironed. All edges on these cones have weld-prep bevels. There is no need to add a seam allowance or tabs as the straight edges are overlapped to create the cone. 8. You want your arc to be the sum of ABxPi. In my case 5.5 inches, so I use a piece of string to measure it.

I would divide the circumference of the cone base (5.5"") by the circumference of the full circle of radius BD (13.35") and multiply the resulting decimal fraction by 360 thus giving me the angle from BD to the arc to give me the shape of the cone template (148.2 degrees). Finally, fold the edges of the wedge together to complete the cone. How to make a cone out of sheet metal with simple hand
