90mm Shaped Charge 1501.2g NG/PETN

[1nemindgypsy]

You must be a complete retard or a real badass thats crazy enough to make nitroglycerin

[woainikmban123]

PETN + NC is better！！

[HDRCX550VE]

@woainikmban123 Hmm, maybe you could achieve a higher density but NG is still much more powerful. :)

[woainikmban123]

太好了 ！！！楼主 我爱你！！！你的雷管是怎么造的？

[lachlan1971]

Explosions FTW!

[scor9977]

that is some bad shit

[NigelGriff]

Holy shit you could kill the occupants of an armored vehicle with that thing.

[BGpilot419]

Fun fact: fertilizer(not sure what kind)+diesel fuel= the same type of explosive used to break through solid rock. >:)

Slovenec? tri dva ENA!

[incognitus001]

@KunarSatan

Da

[KunarSatan]

@incognitus001 To ja :D

[incognitus001]

@KunarSatan

Upam da tvoja izjava nima nobenega nacističnega/nacionalističnega prizvoka...

[KunarSatan]

@incognitus001 Eh joj ne ne =) samo navdušenec nad eksplozivi ki ga je presenetla slovenščina v videu =)

[volucris56]

So this is why I lugged through two years of chemistry.

[snidelywhiplash]

Hm. What are the metal casing components from? The case itself I suppose could be a steel pipe, but the copper cone?

[incognitus001]

@snidelywhiplash

Correct

[incognitus001]

@MineRescuer

I don't think they learn it from here. As there are many more widely avalible reliable sources around (books, some internet pages, their bombmakers...)

[MrAndre762]

what is the easiest way to detonate PETN?

[incognitus001]

@MrAndre762

I believe with common primary explosives like silver azide. I on your place would rather ask what is the safest way to detonate PETN...

[Northhunt]

Do you know what is used for the recrystallization, acetone or alcohol(if so methanol or ethanol)?

[donnelrj01]

@Northhunt

The simplest google search will tell you everything you could want to know. 

[Northhunt]

@donnelrj01 Thanks for the advice. I have done recr. several times before, however I want to know what kind of solvent that was used for this charge. ;)

[donnelrj01]

@Northhunt

He used acetone.

[Northhunt]

@donnelrj01 I see. But this is why I wondered, acetone is not suited for petn/etn that is meant for plasticizing, as the crystals gets pretty large and grainy.

[donnelrj01]

@Northhunt

Yeah, that's can be a problem. There are a number of ways around it though. I'll PM you.

[incognitus001]

@Northhunt

What was used for recrystalization of PETN is kinda pointless in this case, since most of mass accounts for nitroglycerine which partially dissolves PETN anyway. But yes I believe acetone was used here...

[Northhunt]

@incognitus001 I kinda knew that on the forhand, but I am a bit curious to know what the big boys use when doing big scale, acetone can be quite expensive. Have anyone ever tried using gasoline btw?

[incognitus001]

@Northhunt

Acetone for cleaning tools is relatively inexpensive. But I don't think gasoline would make as good solvent as acetone, it also doesn't mix with water and could leave you with somewhat contaminated product afterwards.

[theOGslagster127]

would argue with you about music except i like that track take me away plus prodidgy sampled ultramag plus even if i bailed from my tank and was hiding in the woods somewhere behind a tree...... i take it you got afew cents and rolled em flat then i don't know how'd you get that copper cone lads? and id that tube just steel scaffold pole or where'd it come from? nice anyway!!

[incognitus001]

@theOGslagster127

Nah! Copper cone was made out from copper cylinder using a lathe... Steel casing was bought in some metal shop(6.3mm thick 89.5mm inner diameter steel "weldless pipe"). Thanks for the compliments!

[theOGslagster127]

if like me you live in the uk

then your "playground" only comes around once in a while when

your neighbours on either side both go out shopping at the same time.

whenever that happens you can go out in the back garden and hit some nail gun cartridges with a hammer -

if you're using Hilti then the red strips are okay but i would definitely recommend ear-pro if you are hitting the black ones.

fckng great to watch these guys tho..

who really know their stuff

and found somewhere they can play!!

[Enigma4072]

@theOGslagster127 It doesn't have to be copper. Glass works just as well, or some say better. (Try the top of a martini glass)

[AustralianPyromaniac]

Great video!

You're lucky to have such a big "playground". The nearest one to me is 2 hours away by car...

Do you absolutely require fuming nitric acid for PETN? I can only get 70%. Oh, and last thing, would 500mg of silver acetylide be sufficient for, say, a 200g charge, or would I need to add ~2g ETN?

[incognitus001]

@AustralianPyromaniac

Well my playground is included in larger scattered area :)

- No, you don't.

- I suggest using few 10mg of primary and few g of PETN or ETN instead, scale down primary as much as you can.

[dawson01912]

@incognitus001

What was detonator composed off?

I'm definitely not replicating this amount of work. Very impressive,btw.

I have a forum called Detonator Projects. It's for HE intermediaries and up, but everyone is welcome.

Hope you can join and share ideas. I also have a tutorial for NPED detonator.

detonatorprojects.forumotion.c­o

[incognitus001]

@dawson01912

Booster was test tube filled with ~15g of NG/PETN/RDX, in which a tube of electrical powered lightbulb with glass stripped off inside a straw closed with duct tape first filled with AgN3, then PETN both pressed and sealed with duct tape had been placed.

[dawson01912]

@incognitus001

So, silver azide in a Christmas light igniter. You didn't measure how much AgN3 you put? I thnk the Christmas light igniters are dangereous since they they have very high resistance and need very little energy to ignite. A regular 3AAA battery can light it up.

[incognitus001]

@dawson01912

I don't think there's anything wrong with that, I would be more worried about AgN3 being potentially incompatible with materials in wire filling. It was pointless to measure exact ammount of AgN3 used, but it's on the order of 100miligrams. High resistance and little energy to ignite means also you need weaker power supply and could use longer cables to set it off reliably.

[dawson01912]

@incognitus001

I think it'd be justified to bring a car battery for such an occasion, so energy wouldn't be a problem. I don't know, I used them as a noobie, but then started to use nicrhome wire 26 AWG and up. Safety has no price.

[WestEast3259585]

You are my hero!!!

[ExothermicVideos]

Excellent video!

I wish to someday do large detonations and experiment with shape charges.

[sakoshooter48]

Very Nice indeed!

[imjustwonderful]

how far were you from the blast? i see your alive, so i assume you were very far. or behind a bunker

[incognitus001]

@imjustwonderful

30-40m behind a thick tree

[imjustwonderful]

@incognitus001 haha good god. how didnt the camera get shrapnel?

[incognitus001]

@imjustwonderful

I see my camera either as having a high survivability probability or as disposable :D

300g PETN/NG linear shaped charge on 5m broke it's speaker so it didn't play sound anymore, 30kg of ANNM on 50m magically fixed that problem :)

Only the last 170kg ANFO blast irreparably fucked up iris of the camera so you have to manually help it open (too bad it hadn't been placed 10 or 15m closer :D)

[G0rk42]

@incognitus001

I thought you didn't make this vid ;)

[GunPhysics]

Is the mixture in 1:11 made to achieve neutral oxygen balance or is it just to make it more easier to handle?

[incognitus001]

@GunPhysics

Better OB, higher and more homogenous density + detonation velocity

[AZPrecision]

Bravo

[LowLevelHellProject]

Absolutely takes the cake for amateur shaped charge production. You should be getting paid for this kind of art.

This is everything I wanted in an SC. Couldn't have done better myself.

Lovely work as always.

Stay safe Nuke.

[Northhunt]

how did you make the liner btw? any fancy tool and a copper plate O.o?

[incognitus001]

@Northhunt

From what I know solid piece of copper was modified into liner using lathe along with some custom made tools it was also polished to 1/10mm precision

[Northhunt]

whats the name of the song? thinking about using it in a future project..

[incognitus001]

@Northhunt The Prodigy - Warriors Dance(future funk squads rave soldier mix)

If you watched whole video you would see it

[TheCrazyFinn]

A treehugger gave thumbs down. =)

[incognitus001]

@TheCrazyFinn

I don't blaime them...

[georgewashington92]

@incognitus001 what was the blasting cap made of?

[incognitus001]

@georgewashington92

Two stages of joy one "massed" around 15 grams and had a constitution of PETN/NG/RDX in that composition it lay a tube filled with pressed PETN and AgN3 on top, following a small lightbulb which had been hardwired to even more wires and ultimately to medium sized galvanic cell which generated electron flow which caused sudden change in internal energy of circuit's most resistive part, which failed in some time causing critical ammount of nearby silver salt to decompose...

[h8machine123]

Wow thats some serious damage i wasnt expecting such a big bang from that charge. Amazing how far the shrapnell went. Verry dangerous indeed. HHAHAHA

But really enjoyable to watch though.

[zhmapper]

You, sir, are a god amongst men.

[78945612336266]

@zhmapper what the fuck r u retarded short head how many men better than him u live in lizard hole or what no joke straight fact

[BenHBX]

1:11-1:16-the most beautiful thing I've ever seen!

[bomber101581]

SCIENCE! 

[SugChemist]

Very nice :D

And where do you get that the poor 39kg ??

422mm it's very strong

[incognitus001]

@SugChemist

That poor 39kilo piece of steel was from trashyard :)

[XBiteABulletX]

Wher do you get that Cone and the tube?

[incognitus001]

@XBiteABulletX

Metal shops and lathe ;)

[Arterisser]

i hope UT wont ban ur acc again, ur the best pirotechnic imo

really good and professional stuff, keep it up
