Sheet metal working

FABRICATION

Two years ago I posted an inquiry for ideas about how best to form a double curved cone.

We use these in elevated water tanks for municipalities for their drinking water supply.

The cone is a smooth or flared transition between the stem of the tank and the sphere. The tank is similar to a golf ball on a tee. It is known as a water sphere type tank. The flared cone goes between the shaft or stem of the tank and the sphere on top.

New to the site so I thought perhaps I ought to share a few of my initial pieces, '07-'08, first: hand hammered, 16 ga. sheet metal used for upper + lower (lower not pictured) shells, head, neck and feet.

I'm new here, so Hello!!! I love seeing everyones work! Its All So great!

Here's my latest project. Its 18 gauge sheet, with a 3/16 rod skeleton supporting it. Each element bolts to that skeleton behind the work. (I like to paint my work in auto paint, so it has to be able to separate to get great coverage) Lets see.. used a mig, e wheel, planisher, bead roller, band saw, grinders, two setting D/A sander, and hand drill.

hand hammered visor- let me see if this works! (or visor part III-the return of the upload)

this should work! if it does, there should be an animated .gif included in this post.
this is a test I had starting working on. The final piece is to be a visor for a helmet,specifically a type called a sallet. I liked the way the profile came out but was unhappy with the contours on most of the other views. This was made from a piece of cold rolled 18 ga steel. I used a dishing form and a few stakes to get the shape, the eyeslot was rough cut with an angle grinder, then chiseled a but and then filed to get the round corners a bit neater. On the final, I will actually build the helmet top first then take a pattern off of that to ensure the visor fits well.

Cone Bender

This is a concept of a less than $10.00 cone bender that could concievably bump-bend a cone. A couple of simple sticks of flat bar with another one bolted loosely between. Depending on the space between at each end, you could make a fine cone with light sheet metal with this.

How to make a cone out of sheet metal

I have been doing cone out of sheet metal and today I was wondering if there was an easier way to do than my way wichh is to trace it on metal and then roll it to shape and spot weld it in place. Do you guys or lady out there have any better way or easier way to do it.
