Hi I am using sheet metal to make medieval helmets, I was able to get a bucket type thing down very well with a movable visor and everything, But at the top of the helm i can find a way to bowl it out to fit my head.I need to find a way to measure my head with paper to make patters, so I can copy those onto metal and hammer it into a helm.The sheet metal is soft enough so that if you push and pull really hard then you can bend it but it still holds its shape really well unless you give it a hammering. Im not using heating ether.How should i do it?
Well, an electric blanket works faster to warm up my old body!??
no it isn't D i miss the cold. i live in puerto rico and it's like is always summer :
Nope, except maybe a nice bottle of wine and a great guy to share it with.
Just put the sheet metal on your head and hit with a hammer.
As you hammer a flat piece of metal, simultaneously lift the edge and turn the sheet. The hammering softens the metal a bit so that each hit and lift will add to a permanent bend in it. By rotating between each hit, this bending translates to a bowl shaped warp. As each full rotation is made, you hammer a bit farther away from the center, increasing the bowl shape into a larger and gradually larger bowl. Only your own eye can tell how much hammering and lifting you need to make the proper shape and size of the bowl. I think trial and error, as you fit the bowl on top of your head, will tell you when and where to hammer some more and when and where to stop.
