could you show me the EVA helmet images, i am also building one. do you think that using vacuum molding for the visor would be better, or, i have found a different method of molding it. i asked around on the internet, and found that i could use an oven, heat up the plastic, then with my hands, stretch it over the mould into shape. What would you suggest? this is the last obstacle before i can begin adding eva foam for detail.
