I... hold no one else but myself responsible for anything that happens to myself there in...
Aside from the poor sap who happens to land a shot that takes out your eye. Regardless: no. Short of actively
ordering you not to go ahead with this build, there's not much the 405th can do but cross our fingers and dearly hope that you won't be as foolhardy as to actually go through with this project.
With any luck, however, the decision will be out of your hands - any marshal worth to brain cells wouldn't even
dream of letting you onto the field in homemade gear.
as well I will not be using house-grade materials for any of this
Fibreglass is considered a house-grade material. Most home-made vacuum formers only use house-grade plastics (you'd be hard-pressed to home-build a vacuum former capable of pulling more than perhaps 3-4mm of acrylic sheet). Believe me - nothing you can get your hands on will stand up to the stresses you're going to be putting it through. As I mentioned - fibreglass will easily shatter under sharp impacts, most vacuum-formed plastics aren't up to the task of taking a hit, and you're going to be
very hard-pressed to get your hands on visor materials that are compliant. The glue holding your visor in place is also likely to end up flubbing it, and nobody wants to risk their visor falling out during a match.
if I have to use a different material for the rest of the helmet as well impact grade plastic that is used in most airsoft masks and all paintball masks I will
A step in the right direction, but that still doesn't make your plan any more feasible. See below.
... This is an idea derived by myself to open up my field of vision on the field that would otherwise be limited by goggles
I do believe that a mask with a larger field of view would be quite easy to find, and would be a lot safer than building your own gear. Regardless of that - with the exception of perhaps one or two helmets within Halo's armoury,
no helmet is going to offer you much of an increase in your field of vision.
I will be testing, re-testing, testing again, every helmet I make to be sure it stands up to regulations on any Airsoft and Paintball Field...
I'm not sure you have any real idea of how rigorous the certification process for sports safety gear is, nor do I think you've considered the fact that self-certification isn't going to cut it. These masks are tested
to destruction before going into production - you can't simply throw some stronger materials at your project and hope that things are going to work out. You can't just say 'well, I'll throw some ABS plastic at it, it'll be fine, right?'. Likewise, any official paintball/airsoft marshal is going to take one look at your kit, see that it's not officially rated to the required industry standards, and refuse you entry onto the field - put simply,
homemade gear is a liability nobody wants to deal with. There's a
very good reason for industry standards on combat sports safety gear, and
nothing you produce at home is even going to come
close to offering the protection you're going to need on the field.
Most of us have been paintballing at some point. Yes, it's annoying to have your mask fog up, and yes, it's annoying to get taken out by something outside of your peripheral vision. It also hurts like hell when you get shot in the arse, or your 'nads - let's not try to find out how much getting a paintball embedded in your eye socket is, yes? Please don't be stubborn, please don't put your own personal safety on the line.
Stick to the official gear.
