Me? I plan on using an old nos fogger system and some TIG welded chromoly steel for my cannon.
Safely, of course, following the rules of physics.

The whole thing cost about 110bucks. Ok, I will admit, I do not know a damn thing about physics, I make all my **** with "niginometry", but who cares, it works, and its inexpensive, which is again.... the whole reason for me doing things, right?
If you'd like, I can go through and explain why Liquid, yourself, and Impreza have all made incorrect physical assumptions. But personally, I would just drop it. No one is winning here.
Well, i think it would be nice to have someone who is "knowledgeable" on the subject at which EVERYONE in this thread is wrong in help us all out, instead of just mearly telling us we are wrong. I mean, that is the point of the forum correct? to help each other out, not just saying "you're wrong, im god, i own you" I will agree though, for this nonsence to stop, and discuss the matter at hand like civilized people, instead of bringing up old conversations and name calling, and just plain trying to degrade the other.
Bingoboy, i agree with you, i dont see the big deal with that little roof. I dont see where it really matters what its made of, its just a panel. But, what do i know right?
Charles.

A thread on my upcoming business has turned to nothing but bitching and bickering. Thanks Justin.
Mods, keep the thread, just delete the 1st few posts and change the title. I'll make another post when I actually get rolling. The "troublemakers"
can have this one.

that is a really bad idea. i wouldnt venture into something like that myself but if you are willing to take the risk, go ahead. if anyone rolls their car without any bracing in the sunroof its gonna pop down into their heads. and lets hope they dont roll on rocks.
charles:
Ok smart guy, what if the sunroof is open? how much of that "cockpit reinforcment" is being put to use then? If he is so stupid (which i dont think he is personally) let the man be "stupid" all he wants, its his car. Stop playing mommy.
you little kids are othin but a bunh of jackasses. i never told anyone they were stupid for doing this. i said it is dangerous. all i tried to do is help, but some pothead high school little **** has to come on and try to crack on me. i get tired of this bullshit. you guys really have your heads up your asses. little ***** always come on here and instead of just disagreeing with me gotta, try to make me look stupid. you people take this **** way too serious. take your little forum community and shove it up your ***. i learned A LOT from this, back wen the amatuers listened to the guys who know, instead of waving their dicks in the air like a bunch of cocky *****.
kevin, i didnt say that last part.
sean, i am not an engineering major but dont tell me i dont know my physics. physics is a large part of my major as well.
charles, i wasnt talking about the side glass i was obviously talking about the windshield, which IS safety glass, i know exactly what it is. and dont you think that if it was neccessary to have safety glass on the sides and back it would be there. the reason it is in front is because objects flying at the front of the car could cause it to shatter. at high speed theywould be come tiny bullets and they would also allow the objects to come in the car. you really have noo clue what you are talking about.

Justin, just do me a favor, and stay out of my threads. You seem to do nothing but attract a lot of BS with you're "I'm smarter than thou" attitude, and it's not appreciated. If you want to have a little bitching match with other forum members, be my guest. Just lay off in my threads.

Justin- I obviously was just being a smart ***, i dont think that tiny bullets are going to kill us. But if the sun roof caving in and knocking someone out is a possibility (which you said so yourself) and a peice of straw can kill us, why cant a square peice of glass? You didnt specify which windows you were talking about. I know the front window is safty glass, and i knew that the sides broke in squares (i didnt, however, know that it was called specifically "tempered" but i knew it wasnt regular glass).
Im such a pot head high schooler that im going to college for electronic and computer engineering, and have regular drug test for my countys fire department training. You obviously have no idea what YOU are talking about.
Nice name calling, maybe you are the one that should grow up.
I do appologize, however, once again for "instigating" as i am guilty of it, and man enough to admit it. But im not an idiot nor a jackass, and dont appreciate being called so.
Liquid- Make the damn sun roofs already, you have a buyer right here. Im not worried about dying from it, there are more important things to worry about before i worry about killer sun roofs.

i was thinking of making a CF sunroof my self. One that doesnt open and so on... This way i could put in a thinner head liner and have more head room. I dont feel that putting in a CF sunroof is a safty hazard. Ill let you know if i die, cuz i do race the big tracks.

i did specify which window i was talking about when i said it is "safety glass". since the windshield is the only one which is technically called Safety Glass. i guess i shouldnt assume these are well known facts.
you are right i dont know a damn thing about you. except you have misread everything i have written, you have no knowledge of physics, and you for some reason like to insult me. so that is what i know

Well, i said "so we should tape our glass up", i was talking about all the glass. Then you said something to the effect of "no you jackass, you are stupid, and an idiot, and you dont have to tape your glass because its safty glass".. No where did you say anything to the effect of "you might have to tape the sides up if you want to, because if a peice of straw can go through a telephone pole, therefor a square peice of glass might be dangerous" I think the sides of the car, including the side glass, is more of a danger than a sun roof. I would be willing to bet most crashes are either head on, or side impact. I mean, you see car companies making front air bags, as well as side air bags, but i have yet to see (not saying their arnt) air bags from the roof down. Seat belts should keep you in place, but i guess not if they have to make air bags in the first place.
Bah, its all in good fun anyways, who cares

OH! I didn't realise you were running your PVC cannon pneumatically. The typical user uses explosive gas, and I have personally seen someone blow one apart (tripod mounted) using propane injection.
60 psi seems a little weak. Why not go for 150 psi? That's what we ran on our Pneumatic cannon.

Tempered glass breaks up into shards too small to be dangerous... Remeber the law of conservation of momentum, and the law of conservation of energy. The glass shards would not have enough momentum to do any damage at the relatively low speeds of vehicle travel.
A sunroof would be a bit more dangerous b/c it has a significant mass. It will have a higher momentum at lower speeds. However, if the CF sunroof has enough material around the edges to allow it to still be mounted into the rails, it should be stiff enough to stay in place during a roll.
The stock sunroof is metal, and has bracing to keep it from bending and shearing and making sharp edges of iron, which could easily sever the driver. As while, metal really only likes to be ebnt once, so if it bent against the driver, it would be pinned there.
CF would shear into fibers, which would be pretty harmless, and would not retain its shape pressed up against the driver.
That good enough? I can get some eq's related to speed and mass if you'd like, and some force/shear strength of CF versus sheet metal eq's... but I doubt they'd be of much use.
Up to you.

And no, i dont think the tempered glass squares will kill you, just me being a smart ***.
