I need to fabricate a conical tube. The inlet diameter is approximately 2 inches; outlet diameter is 4 inches. The half angle should not exceed 3 degrees. This means an overall length around 18 inches. I prefer to use aluminum .06 - .10 inches thick. If there is nothing close I can buy, I was thinking to roll and weld the part. Any suggestions?

Correction. Forget my post. It's wrong.
The correct answer is the plane section is developed by starting with a sector of a circle with a wedge angle of 20 degrees and a radius of twice 18 inches or 36 inches. Now truncate the sector by cutting off at a radius of 18 inches.
