I cut the metal out of 13g mild steel using a cutting wheel on my angle grinder and dished with a weighted rawhide hammer in my medium dishing stump. I had difficulty getting the edges to line up as you can see in the pictures below. Doug Strong told me that I had dished them too much and needed to flatten them out to fit them. After much coercing of the metal I got them to fit together and ready to weld, but it did not fit on my head anymore. I began to get frustrated and thought that this helmet was going to end up sitting abandoned on my Wall of Shame.

I am also making a conical visor to go with this helmet. This visor is made from the same 13 gauge mild steel the helmet is made from. Like the helmet, the visor shape historically would have probably been raised from a flat piece of metal, not a welded cone as I have done. To bring the tip to a point, it was necessary for me to apply some heat with a MAPP gas torch to persuade the metal to the correct shape. I used a weighted rawhide hammer for cold shaping and my 20 oz dishing hammer and planishing hammer for the hot work. After I was finally able to get the edges together, I took it to a welder to weld it for me.
After I got the top of the helmet back from the welder, it was very obvious that I did not shape the top correctly. It was very long in the front to back measurement, and too close together on the side to side measurement. I was not able to even put it on my head since the sides were so close together.
With much effort, I alternated hammering with the weighted rawhide hammer to push the front and back in and the sides out. This was quite difficult to do, especially since the welds did not like to move very much. The front brow was not shaped with the edges flat, edge to edge, but they were at an angle at the time of welding.
I needed to hammer the angle to created the correct profile and a smooth, rounded transition from side to side. I heated the front to red/orange heat the best I could with my MAPP gas torch. With the metal hot, I raised the metal down with my raising hammer. You can see the hammer marks in the first picture below.
I ran into a bit of a problem with the front shaping. The weld really did not want to be moved and really resisted changing shape. I heated it up, but I don't think my MAPP gas torch was quite enough for the task. An acetlene torch would have been better I think. You can see in the next picture below, a hairline crack developed in the weld just to the right of the midline. I needed to have that ground out and rewelded when the welder finished the rest of the welding for me.


I will add more pictures soon.
