Who Has Built A rocket Launcher/ I have!

[MikeeUSA]

I just built a Bazoka type Rocket Launcher, I fires a 1in rocket with a "C" modle rocket engine, It's built out of Some PVC pipe Metal grate/stopper thing( so rocket dosen't fall completly through tube but the gases freely fire out the back) and PVC primer/cement although I havent tested it yet since I made it yesterday, it should reack 1000ft or more [JOY!] /infopop/emoticons/icon_smile.gif ! Who else has done this or something similar, Gryphon!? /infopop/emoticons\icon_wink.gif

you'd want to get a safe distance away when testing that thing... which would be preferebly done in a wide open space... gibs are only fun when they don't happen to you /infopop/emoticons/icon_smile.gif

It is impossible for the glass to be half full or half empty for you see: there is no glass

I have a 15ft elctric "fuse" somewhere I can use

uh

I want to hear about the results of testing you twisted person youì

have a mac...
...but not a clue?

Be extremely careful. I've messed with free-firing engines (without any stablizer fins or anything) and they have a tendency to fly wherever, not in a straight line as you might assume.

 

[Catalyst]

Sorry I misread your post. I guess you are firing a model rocket with stablizer fins. Still be careful though, don't go firing it in your neighborhood /infopop/emoticons\icon_wink.gif

 

[Galaddin]

all the same you should fire it from a fortified position... preferably a bunker /infopop/emoticons/icon_biggrin.gif

My Pocket Rocket

No, I don't mean my penis. I mean the time I found a pepsi can and stuffed a Roman Candle into it, and then ran around firing little flaming balls of stuff into neighbour's yards. Then Mike ran over the Pastor's fence and hedges with his car, and I laughed for several days. But that's another story.

And yes, I still have all my fingers (this is after building home made bombs and molotov cocktails and plastique. I was one messed up kid.)

Why is it scenes of violence and substance abuse are readily consumed by society, but displays of beauty such as the naked body or expressions of emotion such as swearing are treated as taboo?

Because people are ****ing stupid.

 

[Snakeye]

Because violence is something you can bring in the evening news.
Imagine a report about Tori Spelling running naked around a football field.
Now inagine a report about Tori Spelling killing the whole Beverly Hills 90120 crew.

So, which one would you prefer to hear/see in the news?
BTW: I suppose you got internet, so you'll have no troubles finding naked bodies of any kind.

Snakeye

anything you do can get you killed, including doing nothing

 

[MikeeUSA]

I'm using a stripped down Alpha MR with no fins/ but If there is enough weight in the nosecon there should be no prob. but I could be wrong!??? /infopop/emoticons\icon_wink.gif

[Gryphon]

Kewl. I've been tempted to build one although I never got around to it. I usually just launch explosives out of HDPE mortars.

You'll want to be careful with that PVC though. If something explodes in it, it will turn to razor-sharp plastic shrapnel which will shred your flesh into a bloody pulp. And plastic doesn't show up on X-ray. /infopop/emoticons/icon_frown.gif Be careful out there....

You guys shoudl try what I did last summer. First, we used a 25ft piece of thick twine soaked in kerosine to set fire to a crate full of firecrackers, 5 M80's(i think) and various rocket engines and other explosive and flammable things. All of this was done in a huge sandlot/field type thing near Cookeville TN. Wicked cool... the fireball looked like a fricken mushroom cloud and IT WAS HUGE!!!! My friend and I were probably 45-50ft away from it when it went off, and it singed the hair off of his arm and my legs. Now that I look back on it, it was probably stupid, but hey, we got the neighbors to call the police! /infopop/emoticons/icon_smile.gif

The most practical home launcher type thing I've ever built was an metal potato cannon (made it out of a fire extinguisher can and 6 feet of aluminum pipe). It had its own propane feed, double cut off valves, and a beautiful sparkplug+BBQ piezo ignition system. It was a beauty.

You just stuffed the potato down, fed it a couple seconds of propane, and fired away. Oh man, just talking about it get me all hot and bothered.


BTW, I've fired all types of rockets from a plain, open pvc pipe, and as long as the rocket is nice and balanced (either from the stick at the end of the "disposable" ones, or from nose weight and fins), you'll have no problem.

 

[WHY]

Stability

Why not make it so that the fins flick out after it leaves the tube.

 

[Catalyst]

I would definitely put fins on it. I think it will probably tumble out of control without them. Just look at any missile the military has; they all have fins.

[MikeeUSA]

How do i make them flip out?

[Catalyst]

That might be hard. A better solution might be to cut grooves in the PVC pipe to slide in the rocket with stablizer fins inside the grooves. This will provide a track from which to launch out.

Catalyst

 

[Derek]

If you try catalyst's idea above, and it works, you can go one step further and cut curved grooves into the pvc, that way, if you build the rocket with the same angle on the fins, you could get some really nice looking launches.

 

[WHY]

OR......

you could probably make some out of cheap plastic, Vut out a shape, with a tab at the bottom that you can fold to the side, use some hot glue or something to attatch the tab to the rocket, and fold the rest of the fin around the body of the rocket.

technically it's the same idea as the rockets they use on attack helicopters.

 

[Derek]

I guess cheap ,flexible plastic fins *could* work, but if they are that flexible, they really wouldn't work as fins because the would bend and flap around during flight, sending the rocket god knows where.
