Shaping BP

[it wasn't me]

I want to blow a gate off its hinges.now I know you can shape plastic explosives into pyramids and such to focus the energy on one point but my problem is that I'm not gonna be using c4 I'm gonna be using black powder.I've a fair amount of experience making `fireworks` :-D and know that when the powder explodes inside a container the blast escapes thru the containers weakest point,naturally,so I'm looking for a container that can 1. hold a fair amount of black powder 2.is solid enough to not blow apart in all directions (as I want to channel the blast towards weakest point) and 3.has a weakest point which I can direct at the gate,so the 2 fireworks mounted on the gate behind both hinges detonate and the blast energy is focused forward against the hinges blowing the gate off.I may use another two on the opposite side for good measure,blowing all four simultaneously.
Has anyone got any idears for such a container,existing or otherwise??? I know I could just kick the gate off its hinges but the point is not to gain entry,I just wanna to blow the gate off :-)

nice shetlan but you missed some of the big ones.
1.... talking about a bomb with intent to destroy property,

2.... posting in forums-discussion instead of explosives and pyrotechnics

3..... the title of his thread violates the rules of the place it should have been posted

but if he only want revenge road kill in the mailbox always works

[headcase]

Edited to be slightly less incriminating. Half-interesting question about shaping BP charges though.

[shetlan]

Mix black powder in acetone (stirring regularly) until it forms a syrup.
You now have a very weak castable explosive.

[CanadianPyro]

Black powder is a deflagrating explosive and as such can't really be 'shaped' in the same sense as a HE. The direction and magnitude of the pressure wave is controlled by the casing. It seems you already know this though.

I would suggest a '2 piece' casing, which uses a strong, uniform casing to contain the powder, and a much stronger, shaped outer shell. Back in his less cautious days, 'a friend of mine' tried this with a CO2 cartridge and a piece of iron plumbing pipe that had been sliced in half lengthwise. He found that it was noticeably more effective at removing stop signs from their posts than a standard COB.

[uchiacon]

I would suggest some AP, I would doubt BP will contain the power to blow off a gate unless you managed to really contain it in the gates hinges.

I would also suggest a can of butane used to shatter the lock if you just want to get through the gate instead of blasting it down with considerable noise.

[_Th0r_]

There's no way BP will be able to destroy a gate. The most you could do is confine the BP, ignite it and then propel the material used to confine it at the gate. Of course it doesn't actually destroy the gate, so it's fair to say it's useless.

Acetone Peroxide would be a good bet but I'm willing to bet you wouldn't be able to obtain the Acetone, Hydrogen Peroxide and all other chemicals involved in the synthesis of AP.

[X-ray Cat]

Making a shaped charge using acetone peroxide is pretty straight out retarded. It will work, but it is dangerous, and once again, retarded... Any imbecile can make acetone peroxide though. If this guy is unable to get the chemicals necessary for it's synthesis I doubt he's actually capable of wiping his own ass...

[[Lt]]

Well I've shaped bp into small pelets using a 10ml syringe but this sounds a bit more radical than that.

[needzhelp]

a piece of iron plumbing pipe that had been sliced in half lengthwise

i like that idea for a shaped charges
would a Vaseline plastic with an AP blasting cap with an iron pipe as described above work?

more on shaped charges:

(i wanna try and make one of those) /\

Shit, shaped charges are easy.

Slice a coffee can in half, vertically. You now have a concave container. Lay it horizontally, and put detcord (or whatever you use to trigger the primary charge) and then place the charge over it. Take a ziploc gallon bag, and fill it with water. glue it on to the main charge, with the booster underneath it, try to keep the charge as on piece. Put some double sided sticky foam onto the ziploc bag, and you now have a concave charge that will:
Blow a door off it's hinges
And reduce risk of a fire.

Edit: Hell, you can make one out of a martini glass, I've seen a buddy (the one that taught me the above trick) do it before.

Slice a coffee can in half - you now have hlaf a coffee can, which will have absolutely no chance of directing the explosive force.

That's one of the most laughable shapecharge methods I've ever heard.

Additionally, the question wasn't "how to make a shape charge" it was "how to make a castable explosive".

If it is so laughable, then why did I learn it from a Marine, who learned it in weapons training?

Also, the point of it is to send water through the door, knocking it off it's hinges, as well as dousing the area with water. I did admittedly mislabel it as a shaped charge when in reality it was a breaching charge. My bad.

There's a very simple answer to that - you didn't. No Marine who completed basic weapons training would be stupid enough to think that would work as a shape-charge.

As a breaking charge, that "might" work - with a major emphasis on "might".

[STS-103]

Actually, it does work.
And, I can prove Marines use it.

So prove it.
Why do you people keep claiming you can prove something if you're not going to post the actual proof.

[STS-103]

Chill Shetlan, I just needed to borrow a book that documents the use of this from my friend.

Pg 87-88 paragraphs 5-6 of the Book MARINE ISBN 0-425-154154-8 by Tom Clancy. I'm using this as a reference as I doubt any of you will believe anything less.

Wow, that's . . . unbelievably stupid.
My god, you're referencing a work of fiction as your proof - that's pathetic.

If it is fiction, then why does it say NONFICTION in bold on the back?
If you could please explain this since I am so pathetic, that would be helpful.

[Timm]

Man shetlan must be really full of shit.. Doesn't believe a word anyone else says! The design sounds plausible, the marines have discovered the power of water it seems in the last handful of years or so, would like to see the details of such a device.

[shetlan]

My apologies to STS-103 I jumped the gun on assuming that was a work of fiction (as most of the books bearing the Tom Clancy name are).

None the less, I remain sceptical of the breaching method.

Timm,

How often do people come on the site and make up bullshit just like this - claiming that they learned it from "their friend" who is a marine? And how often does it turn out to be a total lie?

I question people because I'm tired of the site being dragged down by dozens of children who think that they're cleaver little anarchists.

No worries, I do the same on other forums; I also was skeptical of the breaching method, it's not the easiest to use, but damn, when it works it really does works.

It might be HIS gate; you don't know that. He may have a mine and have a blasting permit; that would make it legal, too. Assumptions will get you blown up around this subject....

Not that often. Most have provided proof. May I say, I'm still waiting for some of yours....?

And," Death of light":

1) No; he did not infer a "bomb"---a bomb is intended/used to hurt/deter/kill people.
2) Was in under Explosives; proper forum
3) Ditto.

[shetlan]

fingers if he had a mine and a blasting permit, he would be hiring a licensed and bonded demolitions specialist to consult him - and to perform the actual blast.

Seriously, even you aren't that stupid

[Ponchiazz]

Sorry for the noob question: BP is a deflagration-only explosive?
Even confined and tightened it does not detonate?
