psyco_1322 Posted June 23, 2008 Share Posted June 23, 2008 Hmm yes I forgot to mention that you should powder it, before drying. I dryed my on a cookie sheet, but that was in prilled form for other uses and general storage. Link to comment Share on other sites More sharing options...
AprenticeChemist Posted June 23, 2008 Share Posted June 23, 2008 (edited) I'm trying to make some TATP only for a binary impact target. Just to get practice for one of my buddy that has a 50 cal rifle and they go out and shoot 50 gal propane tanks. Dangerous I know.Wow ive seen maybe 5 posts from you and I can already tell exactly why you got kicked out of the HE section. Seriously thats one of the dumbest things to try if you are wanting people to think you are responsible. Like stated before there are plenty of better alternatives considering the ammount of AP you would need to make it worth trying out is stupid. If anything like someone said you'd might as well go with a secondary. [deleted] But seriously shooting a 50gallon propane tank is the dumbest fucking thing in the world. I mean I could forgive trying one of those small green ones or even one of the gas grill ones but a 50gal? You are just asking for trouble. Ill admit i've done some stupid shit like shooting a kerosene can with some tracers causing a small fireball and fire. But if you want people to respect you and think you are responsible you don't want to be doing stupid shit like making a primary to help you blow up a 50gal propane tank with your friends .50cal rifle. Almost all of us have done some stupid shit in our lives but if you want people on here to respect you, you had better shape up. I'll be the first to admit ive done some dumb ass things and stupid shit but i've grown up a little since when I first started.

Mumbles Posted June 23, 2008 Share Posted June 23, 2008 Might I remind everyone that this isn't the HE section. Practical discussions relating to them are highly frowned upon. As some of it is kind of related and whatnot I'll leave it, but you can count on some edits coming. Link to comment Share on other sites More sharing options...
psyco_1322 Posted June 23, 2008 Share Posted June 23, 2008 I might add that he stated that his friends did the shooting of the 50gal tanks of liquid petrol. He did not say he was doing that, so dont hate on him for the dumb things his friends do, although it may be directly related to what he does. He was talking about making targets. Sorry if my target write up breaks the HE code, just didnt want anyone getting the idea that it is safe to be using primaries as targets. I was just submitting a close alternative to a commonly available exploding target. Link to comment Share on other sites More sharing options...

Mumbles Posted June 23, 2008 Share Posted June 23, 2008 I appreciate it, but I would have prefered not to have to do it at all. I know you haven't been around here in a while, but like I said earlier, we tend to frown upon practical discussions of HE's outside of the HE section. I don't even like seeing anything about AP around regardless. I have a pretty similar view to most here for it really being quite a detriment to the hobby and really too dangerous for the inexperienced to be making it. Just try to keep the discussion of HE to the section please. Link to comment Share on other sites More sharing options...
asilentbob Posted June 23, 2008 Share Posted June 23, 2008 AC, good too see you again, been a while! I'm an advocate for the whole "if you still have noob questions, you havn't read enough." I try to live by this, and its worked very well thus far. When you research on your own for answers you will learn more than you would just getting an answer in ONE thread. Learning safety precautions is one particular area that I feel the above applies to greatly. You will never find all the precautions that should be taken by asking a question in one thread. Theres just too many variables. I feel its best to go around and read a ton from various forums and books so you can get a good idea of what safety precautions people have taken before and have a bit of insight into their effectiveness, by then you should be able to devise ways to protect yourself even more on your own. Hmm thats interesting on the pecan flour swede, I'll have to remember about that. My look on HE discussion here is mixed... part of me wishes to have the replies outright deleted... Part of me wants heavy editing to remove all HE discussion from here. It can be very interesting, but I don't like that this promotes it to make noobs more likely to go learn about it. The sensitivity of peroxides IS NOT EXAGGERATED. Don't fool yourself into thinking otherwise. There are so many variables that come into play and no 2 crystals are the same. My recommendation is to completely avoid HE until such time when you are licensed, much more experienced, and hopefully much wiser. Link to comment Share on other sites More sharing options...
frogy Posted June 23, 2008 Share Posted June 23, 2008 I have no problem keeping all HE discussion off of here... Quite frankly I thought it was mainly the Synthesis and discussion of chemicals in said HEs that were not to be talked about. As Asilentbob, myself, and many others have said before... Explosive peroxides are not to be messed with... The government has been known to do some pretty stupid things (of various countries), yet I do not know of one country that uses Explosive peroxides as a primary (other than suicide bombers). As I highly recommend reading Pyro books before making anything to dangerous, HEs are a completely different subject... I refuse to make a HE without thoroughly researching it. There's tons of E-Books and forums that discuss every type of explosive out there. Let me assure you that I'm not advocating that you go out and make HEs just because you read an E-Book... I'm just saying, FYI, if you ever even think about it... Read a lot first! Pyro's a lot more prettier anyway Link to comment Share on other sites More sharing options...
AprenticeChemist Posted June 23, 2008 Share Posted June 23, 2008 Well when I said the sensitivity was over exagerated, I meant SOMETIMES. It is something you don't want to mess around with but some people have made it out to be as sensitive as a pregnet woman haha just kidding but ive seen people talk about organic peroxides like they were NI3 or something. And its good to see you to bob how you been? And when I was talking about noobs being able to ask a question I didn't mean they should ask and thats all they get their info from. I was talking more along the lines they look around and ask while they look. Because theres some things that might be hard to find specifics on that are easier to understand when you're able to get a more specific answer from a person instead of some book or website. Theres no limit to the ammount of research that should be done. I know when I ever used to have question on pyro I would research the subject and as im researching ask a question to see if anyone else had good input because new members join boards every week so I thread thats a few weeks or months old might have a lot of good info but one of those new members might have experince that he could add but just doesn't because its an old dead thread. I've seen a number of threads that were long since dead that I could have added a tidbit of experince and helpfullness but didn't because no ones posted in them for months and months so why bring it back up.

FrKoNaLeaSh1010 Posted June 25, 2008 Share Posted June 25, 2008 Idk when i first started learning i wasn't spoonfed so I researched and if i still had a question i couldn't figure out then i would post it. Spoonfeeding is bad and so is not helping at all. I think the only reason there is such a big concern with AP is the ease of making it. Pretty much any HE is dangerous in its own right...The proper procedure would be to treat all them them like they will go off at any second so you are careful. I would treat ETN just as I would AP...with the upmost care so it doesn't really matter. Although my HE days are way behind me anyway. Link to comment Share on other sites More sharing options...
50AE Posted June 25, 2008 Share Posted June 25, 2008 I have a question about the human nose. Because is a natural filter, does it fully protect from dust, and what are the maximum particle sizes ? Link to comment Share on other sites More sharing options...
AprenticeChemist Posted June 25, 2008 Share Posted June 25, 2008 HELL TO THE NO!!!!!!! The nose isn't necisarrily a filter in the sense your thinking of, yes theres things in your nose such as mucus or the hairs that HELP prevent certain things from getting into your body but trust me you can try breathing through your nose to help not get dust into your system all you want but don't expect it to be doing any better for your health then your mouth. Id have to say the particle size depends on how much there is. Like I said it has defenses such as the hairs and mucus that will help catch some of the shit but some will still get through especially if theres alot because theres only so much your nose can catch. Now this is just from my understanding. If theres anyone with more anatomy knowledge then me that wants to prove me wrong go ahead because the only anatomy im an expert in is that of the female Link to comment Share on other sites More sharing options...
TheSidewinder Posted June 25, 2008 Share Posted June 25, 2008 The human nose was designed to minimize the airborne earth dust that occurs naturally, and not much more than that. Fine particulates, in miniscule quantities, are trapped by mucous. The hairs within your nose may help filter out bugs, but that's about it.. IT is NOT a substitute for a respirator or even a cheap dust mask (which aren't very good themselves). Link to comment Share on other sites More sharing options...
FrKoNaLeaSh1010 Posted June 26, 2008 Share Posted June 26, 2008 Yeah even after sitting there wearing a cheap dust mask thinking it would help after making a bunch of things. i was still blowing out black snot from charcoal that got around/through them once. I am sure a proper respirator would be much better though. Link to comment Share on other sites More sharing options...
tentacles Posted June 26, 2008 Share Posted June 26, 2008 Now, now, AC, that's not entirely true.. the nose is a natural filter and will block 100% of particles 2 mesh and above, unless they're traveling out of the muzzle of something, or jello.

mike_au Posted June 26, 2008 Share Posted June 26, 2008 I think if you have to ask, you should be wearing a mask Having sanded back my car I can assure you that inhaling enough dust makes you feel like crap (and that $2 dust masks are worthless, go get a respirator). If you are going to be in a really dusty environment, grab some goggles too. Link to comment Share on other sites More sharing options...
FrKoNaLeaSh1010 Posted June 26, 2008 Share Posted June 26, 2008 Does anyone know the ratio for Zn/S rocket propellant or flash powder? I believe it was 67/33 but I lost all my files with compositions in them and since my chems are severely limited this year I am trying to make due with what I have and was thinking of trying it as a star comp or a base mix for a fountain that will have metal flitters added. Link to comment Share on other sites More sharing options...
AprenticeChemist Posted June 26, 2008 Share Posted June 26, 2008 Ive found the best ratio for Zn/S is about a 60/40 by VOLUME. Any time ive weighed it out I had shitty results. But the last 6 times ive made it I just eyed it out in about a 60/40 ratio and got EXTREMLY awesome results. I made a big pile about 1/8lbprobably bigger and when I lit it it all burnt within a few seconds in a big bright green flash. Smaller ammounts just flash right away. Like I said anytime ive ever done actual weighing it out it always burnt shitty and slow and lots of slag left and sulfur left burning. But one day I tried making a batch by eye and was amazed at the results. Its about a 60/40 ratio and normally its a greyish with green tint to it when its mixed. But as far as what ive read online for actual ratio by weight its supposedly like you said. What exactly would 2mesh be id imagine thats at least as big as sand if not bigger?

FrKoNaLeaSh1010 Posted June 26, 2008 Share Posted June 26, 2008 a standard window screen is 12-16mesh usually so 2mesh would be rather large. thanks for the reply to the Zn question. Apprenticechemist i seen that you mentioned going to basic and were in the army. I was considering this lately and have a lot of questions about it so if you are interested in answering some questions about it send me a pm or contact me on aim.

crazyboy25 Posted June 26, 2008 Share Posted June 26, 2008 Well I got my metal aspirator and it looks nice but it has a 3/8" NPT male water inlet. A garden hose uses a 3/4" male fitting. I went to my hardware store and I picked up a 3/4" to 1/2" reducer and a 1/2" to 3/8" bushing I hooked them up sealing all the connections except the hose with Teflon tape. All the connections are perfect and water tight except when I went to attach the 3/4" fitting to the hose I could only screw it in 1mm or so and when I went to turn it on the aspirator worked but the hose to reducer connection shot water everywhere. It would appear as if the hose threads are to far apart while the reducer ones are rather close together. What can I do please help me!!!! Link to comment Share on other sites More sharing options...

frogy Posted June 26, 2008 Share Posted June 26, 2008 I have to say that most all dust smaller than the hole nose can eventually get into your system... The mucus will collect dust until it is "full", or net damp anymore, then the rest will just flow right on through. Though nose hairs and such restrict some objects, most dust can wiggle its way through. Link to comment Share on other sites More sharing options...
Mumbles Posted June 26, 2008 Share Posted June 26, 2008 2 mesh is half an inch in diameter or so. Tentacles was making an analogy something to the effect of a chainlink fence filtering bowling balls. If you are dumb enough to insist on using a cheap respirator, make sure it makes a good seal around your mouth. This means you may have to shave. 2 Head straps minimum. If it's not rated to at least N95, don't even think about it. N95 is the lowest grade I know of as well Some will have rubber or silicone seals that do indeed help. Bad = http://www.silicosis.com/images/respirator3.jpgNotice 1 strap, no seal, and not rated at all. Link to comment Share on other sites More sharing options...
50AE Posted June 26, 2008 Share Posted June 26, 2008 No, I'm not insisting, it's just a question. How does the nose perform. Yes, I admit I don't have a good dust mask, I only got these $2 paper shit things, that don't even seal my nose. Gonna buy myself a good dust mask this week.

frogy Posted June 26, 2008 Share Posted June 26, 2008 I have a North 7700-30M with a Multipurpose Dust\Acid\Organic Vapor cartridge. I can effectively stick my face into a burning pile of sulfur and smell notice, but then take of the make and nearly puke... Of course I must wear goggles since it is only a half-mask. I also have an M40 field protective mask somewhere, though it has no cartridge, as I had to toss the old Chromium one after I found out it was radioactive Link to comment Share on other sites More sharing options...
