proopfor Posted March 14, 2014 Posted March 14, 2014 Hey folks. I've read through several posts on the subject, and have done much research. However the "how to" escapes me. I've created an emergency item that will soon be going to patent. So please excuse me if I'm hazy of the details. However, I'm having issues with an initiator. Having an emergency fire starter that needs a lighter would not make a very good product obviously. Thats where the pull string comes in. I was looking at the armstrong formula. I found the ratios, however how to contain it and mix it safely escapes me. Furthermore, is this stable enough to where I could ship my items from a to b? Is there anything safer, and how to make it? The idea I have would use a small cup, almost like a primer cup. With a hole in the bottom where I will zig zag a pin through. The armstrong mixture (possibly changed with you alls advice) will fill the cup. Fuse will be placed in the tube in close proximity to the cup. Pull pin, poof, fuse goes. the picture below is a pull string fuse I cut off an army arillery simulator that was damaged, and the pin and cup inside. Thanks for you insight.
DasKapital Posted March 15, 2014 Posted March 15, 2014 So what do we get in royalties if we help? How about the liabilities of armstrong's mix being shipped around? 1
proopfor Posted March 15, 2014 Author Posted March 15, 2014 That's why I was asking if there was a safer mix. Hazmat shipping will be a must anyways. But no one will insure or carry an unstable product. Perhaps shipping the initiator separately from the starter would help. But I'd just as soon figure out something more efficient.
schroedinger Posted March 15, 2014 Posted March 15, 2014 (edited) Armstrong mixture gets prepared by wet mixing in small quatities. There ard other formulas based on chlorate and antimony trisulphide which can be ignited by striking against a surface conraining phosphorus or co tain phosphorus, just likethe normal strike anywhere matches. From that point you could start by making your own construction. But why do it insuch a complicated way, look for a fireworks company and buy ready made devices of them. Also helps which the hazmat declaration Also are you sure about your product and the liabilities if you are in a hurry to complete it, and not spending enough time to do some research yourself?

mikeee Posted March 15, 2014 Posted March 15, 2014 Why not use a small pistol primer to ignite the fuse?
FlaMtnBkr Posted March 15, 2014 Posted March 15, 2014 It would probably be worth the money to consult a firework company that makes something similar, if you are prepared to pay for a patent, patent search, and patent attorney. Could it get by with a cap that has a striker and then strike the device to light it? Similar to a road flare? Would probably be a bit more simple and 'safe' but either way should be possible.
ollie1016 Posted March 15, 2014 Posted March 15, 2014 Why not use a small pistol primer to ignite the fuse?Good idea!
nlrfly Posted May 12, 2014 Posted May 12, 2014 Why not use a small pistol primer to ignite the fuse?exactly what the folks reloading M18 Military smoke grenades are using now. they work fine.
boule Posted May 12, 2014 Posted May 12, 2014 But why do it insuch a complicated way, look for a fireworks company and buy ready made devices of them. Also helps which the hazmat declaration Well, if it is going to be a commercial product, this is going to be the way to go! Anything else ist just dicking around and either not meeting the consumers' demands for reliability or opening up oneself to a bunch of nasty lawsuits. For personal use, a hypergolic mixture might just work.
Arthur Posted May 12, 2014 Posted May 12, 2014 In reality you need to start to find a real explosives engineer in your locality who has experience of system design and testing. the system of chemicals and materials you use MUST comply with the UN regs for storage and carriage it's no good designing most of it, the difficult bits are worth the money or a cut in royalties. get the transition from prototype to known product in use in the market place sorted out.
amateurpyro1 Posted June 13, 2014 Posted June 13, 2014 When are you thinking to patent it, and in what country?
Scttgrffths21 Posted June 16, 2014 Posted June 16, 2014 I cant get the picture to load. Does this need to be cold burning, or can there be open flame?
