I´ve been working on the interior of my helmet. I kind a based it on the Riddell mini helmet but also went by own way.
I used padding that came with the helmet and I decided to try to make the inside ear. It is made from sheet plastic 3 mm thick, sprayed with silverpaint, dulled down with 2000 grit sandpaper and then weatherd with pastel powder mixed with water and applied with a sponge.
I plan on cutting a little panel that can be opend so I can fit one of those flat batteries in there for the fans.
I kitbashed it a bit, the pices you see is a muffler from a caprice clasic model car.
I found a hard hat liner at work and used it, I hotglued it in place and used some of the padding to make it fit inside the bucket.
Im gonna make a box similar to the riddel helmet that fits over the keyslots but I´m gonna install a CPU fan in the top to draw air in.
I anyone is intrested I made drawings of the inner ear pice.
It is very simple do make one.
