How to Fabricate a Cone from Sheet Metal (Full Scale Layout Method)

If you’ve ever struggled to make a clean tapered cone out of sheet metal, this method makes it simple and accurate. In this video, I show how to: -Lay out the cone full scale directly on the metal -Use the apex as a pivot point to draw both the small and large diameters -Divide a semicircle to accurately step off the circumference -Transfer those measurements using dividers -Create clean brake lines for bending -Cut, form, and rivet the cone together -This is a practical shop method that doesn’t rely on complicated math—just geometry and layout tools. -Perfect for fabrication, welding, HVAC, or anyone working with sheet metal. 0:00 - Intro 0:33 – What Most People Use (Tools) 0:54 – The Trick That Makes This Work (Layout) 5:21 – Where It Usually Goes Wrong (Cutting & Bending) 7:31 – Does It Actually Fit?
