I'm working on building some custom armor. I have no problem making the armor plates, but... I need help on the helmet. I can make the front and back fairly easy, the RF stalk also, the RF it's self is basicaly a small box, but... the dome is what escapes me. My idea is to solider all of it together and I can cut the visor out of plexi-glass and bend it but still need that dome. Any suggestions?
