I started building my own ironman suit to combine all the fun stuff in to one project.
I´m making a master model for the helmet. From there I create silicon molds from all the parts seperately. By doing this I prevent destroying my model on which I spend at least 40hours of building and sanding. The ears are not attached since I have some nice ideas creating them as hinges for the rear part.
Also the molds are more easily accessible applying resin and fiberglas and I am able to integrate hinges more easily.
The final step before applying silicon is closing all lines with white bondo and put them back symmetrical and all with the same width. Still some hours to go.
