Hey, I was just curious about how one would make 'RPG' projectiles for a home-made rocket launcher (already made). I was thinking AP for the tip or something, sensitive to force, and then something else for the bulk of it (ANFO?). I have no idea though. Any suggestions?

Interesting idea - but isn't AP hypersensitive? I.e. if you were to "launch" it, the shock might detonate it?

this topic has been covered many times and all around is very dangerous i would personally use silver fulminate or double salts before a organic peroxide

and i would use somthing more along the lines of tnt which is surprisingly easyer to make then one would think

but again alround bad idea to many factors to acount for that could go wrong

TNT or dynamite for main charge, ANFO probably too stable for a good det.

strike anywhere matches + folded tissue paper packet of blackpowder/flash/whistlemix, in a deformable nose-cone.

Hypothetically speaking, I might have to run out and buy some strike-anywhere's just to test this.

I;d imagine ANFO would be a royal b*tch to use in a rocket.

This is all given that you can make a rocket and device to shoot it from, and one at that which would not roast the hell out of your face with a 10ft fire dust tail. Try going for that first, then move to a header idea.

I think it would be too risky to do at home, because you will never have the certainty of it working properly. Even if you get a system that works, I would not use it unless I was really really desperate for something, because so many unanticipated failures could happen. Maybe mount it on a robotic tripod or something if you intend to use it for fun. Even military equipment malfunctions sometimes, and they have alot more experience with it. I would never put the thing on my shoulder unless there was a evil CIA armored car trying to kill me.\

Making and getting it to work is one thing, but putting high explosives on your shoulder is another.

Hows about Loading the sucker with Glass Shards. and your explosive choice and using that as an Ap Grenade?

I was really hoping he wouldn't find anything outside of BI. AntiPersonnel is teh only AP....

Also, I agree with psyco/chainhit - I wouldn't dare put this on my shoulder.

Actually, you could make a really little one with a match, striker, some flash, and a bottlerocket. It's 10pm. I'll be back in a bit.


-Edit-

It's 10:40, and the prototype to test for feasability was semi-successful, proving feasability whilst failing to work correctly. The device was constructed of a paper matchbook, a wooden match, approximately .25grams of flashpowder, a 3g weight, and a half-dozen 7cm x 1 cm plastic streamers cut from a plastic bag. These parts were held together with masking tape.

The matchbook was dissassembled, and cut so that it was 1" long, starting from the striking paper. This was then rolled, beginning with the striking paper facing inward, into a slightly conical tube. Tape was used to seal the smaller end and to force it to keep its form. The weight, a metal peg - was taped near the open, wider, end of the device. The flashpowder was then poured in, and the match inserted into the neck of the tube, and held there with as little tape as possible. Finally, a shopping bag was sliced to form a stabilizing tail, which was of course attached with additional tape. The final device was 15cm long

Upon being thrown in the air, the device righted itself into a match-first course, and struck with slight force, probably that of a 4' fall despite its 20foot course. While failing to explode, it did produce some white smoke. Upon dissection, the match seemed to have only burnt on 2 of the 5 faces (ie: front & left, but not top).

Future versions will expirement with using an additional match head below the match, 1/3rd the amount of tail material, cleaner matches (the match was covered with morning-glory dust), and additional flashpowder (.5g, 1g). If these prove unsuccessful, dual striking strips, whistlemix, and blackpowder are all possibilities.

dude that sounds like a really really bad and unsafe idea.

Wouldn't it take too much AP to make the ANFO det? Bearing in mind you have the weight/volume to consider.

Also, i could be wrong, isn't a minimum VoD required to make a shaped charge work? A VoD, that if i remember, ANFO doesn't reach. I could be wrong though.

Hows about Loading the sucker with Glass Shards. and your explosive choice and using that as an Ap Grenade?

glass? glass?? why not just fill the fucking thing with marshmellows

fill the cone with gunpowder so the parachute charge detonates?

or snip the tip of the cone off and put a primer on so it has impact det and a failsafe parachute det

Something electromechanical perhaps? Or maybe utilize a small single-axis accelerometer.

An impact warhead is pretty much out of the question if you cae here for advice, which leaves you with basic chemically fused heads.

A spoulette is perfectly capable of setting of a main charge, which could be a parachute, salute or smoke device for those nifty trail of smoke in mid-air.

The rocket is a much more difficult matter really. Barring fins there's drag stabilization works pretty well, but horizontal flight will be a b*tich no matter how you dress her up.

Might I suggest starting out with airburst mortars?

So i tried the rest of the match + tube + tail... that idea sucks. Totally unreliable, regardless of flash v whistle, # of matchheads, impact speed, etc etc.

Nor will the silver fulminate on crackle-bombs initiate flash powder.


Next ideas: nail+primer+etc

If you want to be really tricksy, vial of sulfuric acid, surrounded by perchlorate+sugar, tissue paper, and then a stronger charge outside of that. NI3 and AP would be the easy, dangerous way out, and thats not nearly as fun. Or what about a bag of quarts and ball bearings?

even a partially retarded kid would know that NI3 would be a fucking retarded idea.. keep your mouth shut if you do not know what your talking about .....

NI3 will go off at the touch of a feather hell it will go off under it's own weight if you have a amount of it ...

If you were gonna mock me for using matches in my firework, that'd I'd understand, but...... I've seen NI3 used for launched impact explosives.

you sir are mistaken no one with any respect for there life would use NI3 for a and impact explosive you would not be able to handle it or launch it with out it exploding

PS dont beleive everything you read on the internet my friend

100 dollars true to my word if you can launch any sustantial amount of NI3 from a sholder launched device without seriously hurting yourself

How about some damp silver nitrate at the back of a tube with a thin glass divider, a thin layer of magnesium powder sat on top of the primary and perhaps a small silver BBto shatter the glass. The downside here is that this would be hideously sensitive so you'd probably want some sort of arming mechanism.

100 dollars true to my word if you can launch any sustantial amount of NI3 from a sholder launched device without seriously hurting yourself

100$ is not enough to make me risk F8cking myself up that bad. All I said is it was possible, not that it was a good idea. Infact, I think I said it would be dangerous. Furthermore, if it was used before it completely dried it'd be quite different. And who's big teddy?

Well if it is sooooo dangerous then why suggest it ?

anything is possible hell it's possible the earth my flood tomorrow with gods mighty rath thou i would not bet on it

just like it is possible this kid might strap NI3 to his sholder with a high order payload and launch it without his head being blown the fuck off

Something involving piezoelectric materials.

Oh, and lmao @ nitrogen triiodide.

Try Armstongs mix:D

probally less likly to go off then NI3 lol

thou both are equally retarded

I've been looking into creating a small ballistic rocket projectile on and off for about a month.

If I were to manufacture something I'd use a spent .223 cal rifle casing... I'd re prime it fill it with a primary that was lightly compressed to try and reduce it detonating on launch.

Basically what you do is have a dowel rod coming from the tip of your nose cone to the primed cartridge then JB weld it into place let it harden and go from there, All you need afterwards is a wooden back plate counter sunk to accept the primed end of the casing and a nail or screw resting at the bottom for a hammer mecanism.

Also might be advisable to have some sort of cushion over the hammer so it only strikes hard enough when impact occurs.

As for how RPGs and the likes are launched if I remember correctly they have a small "push" charge to basically throw the RPG far enough away from the operator of said device to not become a crispy critter... usually they have some sort of disk or movable counter weight to create the back pressure they need to get the device out of the tube and a few feet away before the rocket ignites instead of a solid wall so it doesn't take out an eye socket and knock you on your ass.

Hopefully this helps.

err ... Coming from the guy who's played around with organic chlorates:
Please specify "substantial", "launch" and "seriously hurt" ...

Sustantial meaning 2.5 or more grams of NI3 as a "initiation charge" (must be impact sensative) (no you may not launch a COB wrapped in caps :P ) followed by a primary follwed by a main HE charge of 75-100 grams or more launch in this purpose to be launched horozontally at a angle no greater then 45 degrees vertical and to be propelled by a solid, composite, hybrid, bi propellent, or tri propellent engine that deflagrates and produces no more then a min. Total impulse of 80 N/s and average thrust of 50 N
(which btw even in my simulations that is underpowered really)

As well being that this is a RPG thread the device has to be sholder launched or for purposes of simulated testing can be stationary mounted but has to be launched a min. of 3 times consecutivly with no CATO


and seriously hurt be defined as any cuts bruising missing limbs concussion ear drum shattering shrapnel taking wounds ...


You get the idea :)

I reccomend a tube launch with fin rail's and upper RPG "pin fins" to align the upper part of the body in the tube

Crystalline iodine can be produced by evaporating the ethanol off of a tincture, correct?

Thanks. I don't like trusting &t's text files, but if you vouch for it that's good enough for me, especially because I'm only going for minimal amounts, so poor yield is fine.

You get the idea :)



Okay even *I*''ll pass on *that* shot!

Too much drugs left untried before I end my life in a blaze of glory ... or cloud of pink mist.

If these prove unsuccessful, dual striking strips, whistlemix, and blackpowder are all possibilities.

A minor suggestion, if you want the device to ignite try tucking a flash paper tail into the matchbook along with 2 other stabilizing tails. Light the flash paper, you might want at least 1 foot and 1/2 of it. If this proves successful you might want to try an actual rocket tube.

Squib wired up to a small push-button switch that will detonate/activate the squib when it hits said target?

haha yeh.....and dont even think about it you little kiddies....

I don't get all this. What's wrong with simple electrical ignition on impact? You could stick a pushbutton on the front of the thing, maybe some sort of "burn through" safety mechanism that only completes the circuit after a certain potion of the rocket fuel has been burned, and use a simple wire igniter and a couple of watch batteries to initiate whatever.

Another more reliable route would be a cheap striker (read: spring loaded nail) and a shotgun primer in a tube. Again, use it to initiate whatever you want.

You can't be afraid of a little fabrication. Sure, it'll raise the cost of your projectiles but how many of them do you realistically expect to be able to shoot at stuff?

Non metal screw and nut and two metal contacts, the gyroscopic stabilization will screw the nut down to complete the circuit.

Improvised explosive projectiles can only be of 2 bases :

- A calculated explosion relying on propellant burn-time (like, BP to Detonator to Explosive).

- Same as military-grade, spring/rotation engine.

1) electrical ignition is a third option
2) this isn't a great idea to start with
3) Fate, I seem to recall something similar to this involving CO2 canisters and a flare gun....care to share how that one turned out? :D

I second the request to find out how that turned out. I remember reading about that a while back before I even registered here on Totse

What do you mean, find out how it ended up? The SPC video was front page news for months!

-rewatches-

-"I picked up the smoke cloud off of that one."
-"Outstanding"

That was just the same principle behind 12ga bird bombs. Fused reports. Except with metal. One got stuck in the barrel and it was a close call.

I thought I had the video... but apparently I don't. I have a vid of a successful round though somewhere.

I've wanted to get a flare gun for a while now and shoot crossett comets (a comet with an explosive center that makes it break up into 4 equal pieces, so you get a trial, then an X in the sky) out of it... but no place to really do so...

Does anybody have that video?

Does anybody have that video?

/re-read his last post

/shakes head

Yeah, somewhere out in the brush and brambles back there is my flare gun. I never did find it.

I don't recommend fooling with this, as we all found out just how easily it could all go wrong.

That's one video I never got.

Something involving piezoelectric materials.

My EOD sense is tingling.

piezo's shouldn't be relied on to provide an adequate amount of energy for warfare purposes, which aren't contained in the scope of this forum I might add.

wat

I've had this idea for a while:
using a potato gun, make a specialized round that would carry thermite, using the fire produced when the cannon is fired ignite a fuse that went into the round...

just an idea... probably a bad one

That would be a spoulette. You've got the right idea there.

A fuse wouldn't be that reliable to ignite thermite, Ive done the same thing though using a tennis ball mortar with a tennis ball carrying flash and a fast fuse.

Just make normal aerial shells... they are exploding projectiles...

The problem with potato guns and fused projectiles is that if the fuel your spraying in wets the fuse, it might make it less relible to ignite... AND there is always the possibility that the projectile gets stuck and the fire blows by the side of it... but still lights the fuse...

So just use standard black powder to lift standard aerial shells out of standard mortars, from a standard distance.
