Foam SPI is Back!

Alright, I have an idea for the helmet! Maybe some clear worbla, heat it up and let gravity do the rest sort of, I could vacuum for, just have to make one! Just an idea.

Ah, well might just forego the mirage class helmet then
Check out PETG at your local plastics supplier or hardware store. It's effectively the same material as pop bottles but you can get different thicknesses. If you make a buck the shape of your visor you can heat form it with a heat gun or build a cheapo vacuum former.

Clear Worbla is just not fun stuff to work with. You have to get it stupid hot and then flash chill it to get it to keep it's shape. It's also uneven thickness and gives a beer goggles like effect when looking through it.

Still a work in progress, hoping to have the full chest done today minus the straps, I'm going to put those on last after it's all painted, just to have a cleaner look! The paint job is going to be expensive, but it should be awesome!

I'll be watching this thread, ever since I saw the SPI on the cover of "Ghosts of Onyx" I thought it was one of the more unique armorsets, especially since it's very rounded compared to typical UNSC gear. It'll be exciting to see how it turns out :)

I have no idea. I scaled everything rather specifically to my size, so I couldnt even tell you. I'm slim and 5'6" if that helps the imagination on rough size.
Yeaup, already scaled mine and fits like a glove, I just took 25mm off the default size, so probably do that to all of them! Thanks!
