So I, much like a kid on christmass, promptly set about test fitting the visor into the helmet and grabbing a few shots to make sure its dark enough. Unless you are right up on the visor with your flash on it looks like it will be dark enough. The helmet is possibly just a shade darker than the fabric but its really really close and I have no doubt it will look great sitting on my shoulders once done.
Here's a few pics of the helm, with the visor just sitting loose inside…



That last one where you can see inside, the camera is less than a foot away but you can see from the other shots that you can’t see inside at all without being that close.
And Jester, I'm TOTALLY not planning on doing the blaster at the same time, Just trying to thing towards the future if I needed to do anything special with the belt when I made it the first time. All I've seen on how the belt attaches is just with Velcro so far, If you guys know of a better way I'm all ears.
