Ball Mills, Pyro, Explosives, Tannerite, etc...
There is a maintenance technician job opening not to far away from me for an explosives manufacturer. I meet or exceed all their qualifications except one, explosives certification. So how could I get explosives certification on my own, so I could qualify for the job? On a related topic, I went to a nearby Rural King store and they had Tannerite exploding targets. They are kind of pricey, $7.99 each (half pound) or 29.99 for 4. So anyway, a little research on the internet and I see a video of someone making exploding targets on youtube using instant cold packs with ammonium nitrate and aluminum powder. So I checked at Wal-Mart and found instant cold packs with the ingredients calcium ammonium nitrate, $3 for a 2 pack, the guy on youtube used both packs for one target. So I loaded some aluminum foil in my rock tumbler with steel balls as media, should have a good quantity of German style dark aluminum powder in about a week. This stuff isn't supposed to be illegal as long as you're detonating it with a high powered rifle, I guess where it's legal to shoot a rifle, it's legal to have a target go boom. Would ammonium nitrate and diesel fuel work the same, detonate with a rifle shot? Just wondering because I keep some diesel around for the Kubota tractor/mower, sure would be easier than ball milling aluminum. So, just out of curiosity, would the ammonium nitrate combined with aluminum, magnesium, fuel oil, gasoline, ???? be able to be detonated with a firecracker or flash powder? I'm not sure if the maintenance tech job for the explosives manufacturer pays good enough to interest me, learning about explosives sounds kind of fun though, big firecrackers! :-) RogerN |

It is actually a very stable explosive. AN/AL will (this is what the "exploding targets" are filled with) However you can use the AN/AL as the primary detonating charge for the ANFO. So, just out of curiosity, would the ammonium nitrate combined with aluminum, magnesium, fuel oil, gasoline, ???? be able to be detonated with a firecracker or flash powder? AN/AL could be. I wouldn't try magnesium simply due to the difficulties in making it stable. Standard flash powder is Aluminum powder and potassium perchlorate. When properly mixed it is reasonably stable. It is VERY static sensitive though.

Same for abortion clinics, blowing one up sends customers to another. Change the heart of the customers and the clinics would have to perform other health services or go out of business.

: Isn't Tannerite AN/AL? There's a youtube video on making Tannerite using AN from instant cold packs and 5% AL, the guy shot the AN/AL pack and it went off. It explodes at a sub-sonic velocity; deflagration rather than detonation. Explosives work in two general regimes: "Low", or deflagrating explosives, and "HIGH", or detonating explosives. In sufficient quantities, some explosives will undergo what's called the "D-to-D" or deflagration to detonation transition, as evidenced in the Texas City disaster in 1947, when a cargo ship full of ammonium nitrate first caught fire, then eventually underwent the D-to-D transition and leveled much of the city. Black powder and (when functioning normally) nitrocellulose smokeless propellants used in firearms function by rapid deflagration. When (usually double or triple-based) smokeless powder detonates - like in an under-loaded rifle cartridge - BAD things happen to weapon and shooter. Tannerite, as intended for use, deflagrates. It can be detonated by a # 10 cap or a small high-explosive booster. LLoyd |

: I've seen some exploding targets that are supposed to work with 22 rimfire, wondering what they use to make it more sensitive. I read something about you having a book with some info about ball milling. Still available? Sorry... I didn't answer the rest. Explosives become more sensitive when chemicals with low decomposition temperatures are used. Potassium chlorate is the 'classic' example of a low decomposition temperature oxidizer. That's why it's used in matches. With a low melting temperature fuel like sulfur, KClO3 will decompose at the temperatures reached by friction. With phosphorus available in the mix (on the striker), the temperature is further lowered. With only phosphorus as the fuel, the temperature goes so low as to allow ignition by gentle friction, like just throwing the composition down on a hard surface -- a la the "throw down torpedos" of our youth. Yes, I have a "book" - more a booklet than a book, only 84 pages, et. al. It describes how ball mills work, and gives full construction details with measured drawings on how to build a small "lab" style mill suitable for amateur pyrotechnic powder production. (it will mill about 5lb of powder per run in about 3-1/2 hours from raw ingredients). There's also a lengthy "train of conciousness" section on improvements to the mill and things like selection of and making of milling media. It runs about $20 retail from a number of pyrotechnic literature suppliers like American Fireworks News, Skylighter, and FireFox (all ..coms) I've also published a couple of shorter articles on aerial shell and pyro component manufacturing at the amateur level, and a couple of diatribes on digital firing system use and problems with them.

Let us know how this ends up working, I am very curious. i You may already have this, but if not: http://www.martinfrost.ws/htmlfiles/june2007/imhv3.pdf I ordered some oxidizer chemicals, potassium chlorate and perchlorate. I hear the chlorate is very sensitive, hard to mix without detonation in some substances. My plans are to get out the reloading scale and play with a few grains at a time, so if something goes wrong it should be a minor incident. I don't plan on doing anything illegal, it's just as the government takes away the fun stuff, I'd like to have a little to play with before it's banned. In a few years the chemistry sets will probably involve putting food coloring in water to see the effect, maybe have enough chemicals to make a test tube of tea or something. :-( When I was young we went to the pharmacy and bought potassium nitrate and sulphur off the shelf, mixed it with a mortar and pestle, lit, it burned slowly. We didn't know the right proportions, we mixed roughly equal parts of potassium nitrate, sulphur, and charcoal. Burned slow but it was still fun. RogerN |

... snip I'm not sure if the maintenance tech job for the explosives manufacturer pays good enough to interest me, learning about explosives sounds kind of fun though, big firecrackers! :-) RogerN Let us know how this ends up working, I am very curious. i I saw an ad for the maintenance tech job at the explosives plant, it's a little farther away from me a pays less per hour so I'm not very interested. I have been looking up info on Aluminum powder/ Ammonium Nitrate exploding targets. So far nothing I have read indicates a rifle bullet could detonate the explosive. The blasting caps seem to generally have a powerful primary explosive that sets off a secondary explosive. In general, I didn't see any mention that a secondary explosive could be detonated by smokeless powder and a projectile. I understand an explosive like flash powder isn't a detonation, it just a very fast burn, but if a fast bullet can detonate, couldn't flash powder (or maybe black powder) propel a projectile at 2000 fps to detonate? Has secondary explosives been tested with rifle shots? Is there a list of what can be detonated by a rifle shot? I guess it depends on the situation but if a soldier found himself with more guns than he needed or could carry, it seems it might be easier to point a spare rifle at explosives and rig a trip wire instead of scratch building a blasting cap to detonate. The chemistry behind it all seems interesting to me. I find reading about it interesting but don't want to try to make anything too dangerous. It seems that creating a chemical that can explode, without exploding it, is kind of like setting a mouse trap, but in the case of the explosives, the "trap" going off does more than just snap you in the fingers! Not as dangerous as explosives, I think it would be fun to make some rocket engines and perhaps some colored stars to burn in the sky, but I'm sure that wouldn't be legal here. Vacuum Distillation. The improvised munitions manual from the Army tells about making nitric acid from potassium nitrate and sulfuric acid. It's basically use 2 parts potassium nitrate to 1 part sulfuric acid, and a distillation process to get nitric acid in the receiving container. I have read a little about vacuum distillation, what I like about it, or at least about the setup, is that everything is sealed and has a single tap for the vacuum pump. This seems that it would be a great way to deal with the fumes, even without the vacuum pump you could route the fumes through a tube away from people. This brings me to a distillation process I saw, they use a small bucket of mash inside of a larger bucket, the mash is heated by a small immersion heater, only to about 40-50 deg. C, and the alcohol is collected in the larger bucket that isn't heated. Expanding on that idea, if a vacuum was drawn the alcohol would boil at a lower temperature. Seems that if you made a closed type still, you could pull a vacuum, slightly heat the mash pot and cool the receiving pot, thought this might make fuel strength alcohol more efficiently. I'm not interested in going into big time ethanol production to run my car from it, but I like how chemistry labs produce their chemicals from what they have on hand. With the proper setup I should be able to make charcoal for homemade black powder and get wood alcohol (methanol) at the same time. Or maybe ferment a little sugar water and distilling to make alcohol for the alcohol lamp, instead of paying $7 per quart at Wal-Mart. I guess I'd have to get a permit to make ethanol for an alcohol lamp and science experiments, maybe wood alcohol would better. RogerN |
