That book is pretty inaccurate and full of dangerous suggestions, it has been said that Jared Ledgard knows very little on explosives synthesis. I
wouldn't trust any methods presented in this shitty book. It is discussed further in the thread called 'the worst books ever written'. still seems
very professionaly put together but not very well researched.
i tried to upload it here for you but it is bigger than the 10MB allowed.
i could possibly email the PDF to you if you want to PM me an address to send it.
otherwise try scribd or 4share or another similar file sharing site or even a torrent file ,you will find it somewhere.

NeonPulse i did not expect that it would be such an inaccurate book. !! But it is ok, never mind, something you can get from that one.
Dany thanks, i have it now already.

Can someone help me find a good guide on synthesis of Aluminum hydride (AlH3) with this method ?
3LiAlH4 + AlCl3 > 4AlH3 + 3LiCl
I am sure its on the internet but I cant find it idk why, maybes its because this is a really basic synthesis? I mean.. Theres almost no one that
publishes on how to make NaCl any more..

Hi Solo,
Just to fix the ideas:
2-Methyl-3-(3,4-methylenedioxyphenyl)propanal
hydroxamic acid
Angeli Rimini reaction
My guess is:
2-Methyl-3-(3,4-methylenedioxyphenyl)propanoic acid hydroxamate
Why such an interest for it?
-Perfumery
-Energetic material
-Piperine or Capsaicin like derivative ?

Nitrocellulose Blasting Cap [Help]
Hi,
I want to make detonators with 200-300mg silver acetylide double salts for primary (in little caps see my YT videos )
Intended for secondary i think the nitrocellulose synthesis is more safe than ETN or PETN and easy to reach, but NC is it really stable?
So I want to know how you achieve them, I think hands pressing the NC (cotton synthesis) into a syringe by wetting with water for greater density, is
it risky? and I can not pressing too hard..
I never make nitrocellulose but intends to do soon, there are specific rules to follow? I can store NC.. I heard it must be stored in water, is it
true?
Thanks
Small blasting caps, fingers safe!

Go read this thread. I'm not sure you'll have much luck with it, but either way you need to read more and ask less until you've come up to a certain
level of knowledge. Nobody wants you to get hurt from spoonfeeding.

Lead azide long term stability
Will a lead azide based detonator "go bad" after a certain storage time?
There is lot's of WW2 ordnance in the earth of some countries and often the detonators are in a frightfully good shape.
From what i read lead azide reacts with carbon dioxide from the air - but only when wet. So i assume under dry storage conditions lead azide will
store well over along time.
Did i overlook something here?

Dissolving self amalgamating tape
I have buy some self amalgamating tape and i has trying to dissolve it into gasoline, filter it and let the gasoline to evaporate to obtain pure PIB
rubber. Once i tryed, the gasoline become black-dark, so i guess it started to dissolved. But at the end the final product was something like creamy
like black material at the bottom of the flask filled with gasoline. I guess it is unable to dissolve it completely... Has anyone try something like
that in the past ? or has anyone found a good source of PIB for plasticizing HE ?

You're english is leaving me to wonder what you did or what you didn't do. But you should try to search more as this topic has been dealt with
before. Try this thread. It was one of the earliest posts I saw from quicksilver. He was pretty energetic during his time. I hope things are well.

Try Bird repellent, it is polybutene which is very good with a ricinoleate. I have used this and it is great. You find it in farming supply stores in
a tube to fit in a caulking gun. The plastique you can produce with this stuff has all the desirable properties you want in a plastic explosive. Rat
and bug traps are also a good source but that is usually pib though.

I haven't ever had the best luck with HE plastics, I would always have a crumbly mess with low density, similar to damp material unless I used
excessive amounts of binder (20%), in which case I would get an explosion with black smoke, even with ETN. I always made a solution of PIB in warm
toluene and stirred this with crystalline explosive like ETN or RDX to make a slurry type mass, then work it with my hands till all of the toluene
evaporated.
Anyone know who quicksilver was and why he quit posting??

It sounds interesting, so a bird repellant, Castrol synthetic oil and methanol you are only need to make a perfect plasticizer for HE ??

What is perfect? Quicksilver and neonpulse said it makes a pretty good plastic binder (because it is both plasticizer and binder, you could have PBX
with only a binder but plasticizer is added to increase moldability). There are things that could be improved before you can call it perfect, like a
wide range of acceptable temperature, or being energetic with explosospheres in its formulation, or getting by with 2% plastic binder instead of 10 or
20%. If it were perfect, people would have already quit weapons development since the 1960's when the material was developed and improved.
Turner, if you read his account bio page you'll see he was an older, interesting yet simple guy who disappeared without notice. People have reached out to him with no result. So we
can probably assume what has come of him.

I will really be glad to learn what improvements can be done to this plastic binder in details. The starting materials looks very easy to found. Also
the procedure is as PIB ? You are going to dissolve them into the gasoline or other solvent ?

Rapopart’s Rules for critical commentary:
1. Attempt to re-express your target’s position so clearly, vividly and fairly that your target says: “Thanks, I wish I’d thought of putting it
that way.”
2. List any points of agreement (especially if they are not matters of general or widespread agreement).
3. Mention anything you have learned from your target.
4. Only then are you permitted to say so much as a word of rebuttal or criticism.
