Yankie Posted February 27, 2009 Share Posted February 27, 2009 Wow, thats really weird. OMFG I HAVE PERCHLORATE AT LAST!!!!! I am happy as Larry, dunno who he is but I am sure he is one happy guy. 5kg from spain, made some blue stars and some flash, I now respect flash, 0.2g is about 10 times more powerful than 1g of BP. WOOOO I am so happy Link to comment Share on other sites More sharing options...

Mumbles Posted February 27, 2009 Share Posted February 27, 2009 Any idea on how to back fill the bags to purge out the oxygen? As in a CO2 source? I'm not really aware of any commonly available regulated CO2 sources at home. I don't have a CO2 kegging system unfortunately. I also don't really want to bring edible(sorta) items into the research lab to purge out with nitrogen. They'd be looking at me really weird as I have 4 pounds of hops on the bench next to the Chloroform, LAH, cyanide, and benzene Link to comment Share on other sites More sharing options...

Don't know how clean the CO2 is in those cartridges used in bb guns though. A soda-streamer cartridge would be the first choice except for the price.

Mumbles Posted February 28, 2009 Share Posted February 28, 2009 I'll have a look into the oxygen absorbing packets. Most of the ones I'm familiar with wont work in my situation. Their either activated by air or water. I don't know if "air activation" means it just needs contact with air to pull out the oxygen, or it needs to get started before it can do it's job.

Swede Posted February 28, 2009 Share Posted February 28, 2009 Welder's shop - rent or buy a small argon bottle! I've used argon for topping all sorts of things, especially some casting resins that are very susceptible to oxygen and water. I've used it to back-fill stainless steel foil containers for heat treating metal. And of all things, I've used it to euthanize my kid's pet rodents (gerbils and such) when they are badly injured or have some huge tumour and are in pain. Bone dry, inert gasses are handy.

Mumbles Posted February 28, 2009 Share Posted February 28, 2009 I don't know about the pneumatic tool ones, but the ones for paintball guns often have oil and stuff in them. I don't want in my hops. I've heard this from the one time use canisters at least. I'm unsure about the refillable ones. Link to comment Share on other sites More sharing options...

FrankRizzo Posted March 1, 2009 Share Posted March 1, 2009 (edited) Mine sat in customs for weeks while they ran every test under the sun on it I imagine You should have asked to see the assay results. Would've been interesting to note any impurities. Someone paid for the testing, might as well be useful.

WarezWally Posted March 1, 2009 Share Posted March 1, 2009 (edited) So I take it that perch isn't illegal to import into Aus, a few people have said it was. Where did you get yours from? Its not illegal to import, I have done quite a bit of research into the topic and came to that conclusion. I emailed NICNAS as customs told me to speak to them, they confirmed that importation is fine provided its for personal use. There is a lot more to it than that though. Its illegal to ship though through the Auspost network though. I got mine from a US vendor, helped that I was one of his first customers Customs are idiots, I send them emails asking if was allowed to import laboratory reagents and they had no clue. You should have asked to see the assay results. Would've been interesting to note any impurities. Someone paid for the testing, might as well be useful. It is a US domestic 'strain' Would be nice to know exactly what I purchased. Edited March 1, 2009 by WarezWally Link to comment Share on other sites More sharing options...
WarezWally Posted March 2, 2009 Share Posted March 2, 2009 Does anyone know if rifling would show up on an x-ray? Barrel blanks are cheap and easy to buy in the US, personally I doubt it would show up (couldn't see anything in x-ray photos of rifles) but it doesn't hurt to get a second opinion before I decide to buy one Link to comment Share on other sites More sharing options...

I think it depends upon the equipment customs uses. If the barrel was mixed in with a few other cheap items like DOM tube that have no rifling, it might slip right through. Another option is a homemade rifling machine. This is a hugely popular hobby here in the U.S. and is easier than it sounds. There are guys with a home cut rifling barrel that outperform factory bbl's. Link to comment Share on other sites More sharing options...

Barrel blanks are cheap and easy to buy in the US, personally I doubt it would show up (couldn't see anything in x-ray photos of rifles) but it doesn't hurt to get a second opinion before I decide to buy one I don't think rifling would show up on an actual barrel where the variation in thickness would be negligible but on a liner which is much thinner the difference might be noticeable. I believe that a chambered barrel would be considered a firearm component and would need a license and permission to import, a liner probably wouldn't, a blank would be a bit of a grey area. I agree with Swede, if you could get it mixed with a couple of other bits of metal you would be set. Check out some of the TV shows to get a feel for how the x-ray gear works (I downloaded a couple of dozen episodes of "border patrol" the other week so I could find out a bit more about how they do things, some of it is quite interesting) What caliber are you looking for?

flying fish Posted March 3, 2009 Share Posted March 3, 2009 Wow...anyone else getting rediculous amounts of skylighter spam over the last day? I really need to remove myself from their mailing list. Maybe they really do have some increadable deal going on (what was it, like half off everything or something?), but I just don't care right now! Oh crap, now I feel like a spammer for posting this...

asilentbob Posted March 3, 2009 Share Posted March 3, 2009 (edited) Yeah... they are having a half off type sale... BUT the prices on many of their things has nearly doubled... so just how much money you would be saving is debatable... One of their aluminum powders is at around $38/lb... So yeah. So long skylighter. EDIT:Lately aside from having a ton of school work to catch up on I have dug through a few pyro sites again to find some of the old stuff. Ya know, sites I should have bookmarked but didn't. Looking for various pages with stories though I imagine most of them are on forums and so the links might break after a few years.Diary of a Pyrohttp://www.armory.com/~spcecdt/pyrotech/doap/ORRIHKAL - Oxy Reducer Reactions I Have Known And Lovedhttp://perihelionvfx.com/ORRIHKAL.html Feeling slightly nostalgic... Perhaps reading through I'll remember a bit about what it was like first starting out and then ill be able to help noobs slightly more. Dunno.

FrankRizzo Posted March 3, 2009 Share Posted March 3, 2009 REagrding the Skylighter sale, yeah, Harry's prices are completely off the mark on most of his products. HOWEVER, there are a few books which are a good deal (after the discount), if you're already in the market for them. The Chinese resin star plates aren't too bad either for ~$30.

optimus Posted March 4, 2009 Share Posted March 4, 2009 (edited) I'm looking into doing a little chemistry experiment, synthesizing a rather exotic fuel/colourant. Problem is, I have no idea what I'm doing when it comes to the maths side of things. If anyone here would be kind enough to do a very quick bit of spoonfeeding, I'd be greatly appreciative. I have an extremely limited amount of material and don't want to mess up and waste the lot. Please PM me if you can spare a minute. EDIT: sorry - forgot to mention I'd rather do this via PM for the moment, don't want the experiment out in the public domain quite yet!
