dagabu Posted April 27, 2011 Share Posted April 27, 2011 In any case, it would be great if I could just buy salutes, save myself the danger of making my own, allow a machine to make them instead, and use my time learning the much more challenging skills of color shells, double petals, different effects such as crackling stars, etc. Haven't thought too much about rockets yet. Is there anything I should know about "rocket types"? Rocket types? What does that even mean? Any way, machines are not used to make salutes, here is Mike Rowe from Dirty Jobs working with Albert Knobloch to make a few pounds of flash... http://www.youtube.com/watch?v=W7i0ekL21k8 Link to comment Share on other sites More sharing options...

Yeah, I know a guy that was from the old school and used to work making 5 lbs of flash at a time by screening. The factory he used to work at blew up too. Not from flash I guess, he said they were making a batch of "blue". Some type of blue star comp, no one knows for sure what happened. Theories range from the comp reacting to the employee setting it off when he took the knife to the patty or maybe a spark,etc. Not sure if any of you recognize the train in my profile picture/avatar. I used to work there and I can tell you that Mike Rowe should have visited it before they phased out most of the coal burning steam locomotives. I'll take coal dust, soot, grease over human or animal shit any day but outside of that.... it's the dirtiest job I know of.

SjeefOne Posted April 28, 2011 Share Posted April 28, 2011 I can't say I've seen anyone personally add rice hulls or a bulker to their binary mixed flash salutes. You don't know this person? I think you do! Link to comment Share on other sites More sharing options...
dagabu Posted April 28, 2011 Share Posted April 28, 2011 I'll shoot Nski an email and see if he still does that. I didn't see him adding flash last year, he was working on big stuff when I was walking around between rockets. -dag Link to comment Share on other sites More sharing options...

Pechovski Posted April 30, 2011 Share Posted April 30, 2011 (edited) Regarding flash sensitivity, i do not know if this has been posted here but: http://www.pyrobin.c...20bam%20etc.pdfIt is a report for EU back in 2003, overlooking fireworks used in the region. You can compare it to other compositions and see its sensitivity to both heat, impact and friction i think. It is very educational to, i have not read everything through yet myself.Found it on passfire. EDIT: And for my opinion on Salutes (if its worth anything), I just do bigger flash bags (i.e 4x30g for my 3" canister), put them symmetrical around my break, fill gaps with BP or hulls and add Ti flakes at top. Gently tap the casing to make the ti spread evenly.The flash will not roll around freely, the shell gets filled and the Ti do not come in contact with the flash. Though if the Ti would spark i dont think it would help anyway, you could just use a non sensitive filler.

PurpleFlare Posted May 10, 2011 Share Posted May 10, 2011 I can't even start to explain how grateful I am that you posted this safety guideline! This thread has really humbled me big time. This is coming from someone who used to play with gun powder and is pretty familiarized with what damages explosive can do to a human. I was really looking for items to make a flash powder for last couple days but I was told it is illegal to make it. So I look it up and came across this thread and spent a bit time reading it. Normally I laugh when running from something I just lit and feeling/watching it exploding. But after reading about the damage flash powder is capable of, hair on back of my neck literally stand up and I was literally scared! Thanks for posting this thread! I really appreciate it!

xtr55 Posted December 12, 2011 Share Posted December 12, 2011 Speaking of pros, the safest method I've seen for making flash inserts commercially involved separate sized scoops for perchlorate and dark aluminum and filling the prepared paper casings with the separate components, then rolling the closed casings down little wooden ramps to mix the contents inside. After all this the inserts were built into the shells. They worked flawlessly and cut out the hazards of personally mixing and handling flash. I think the perchlorate was freshly milled which made it sort of fluffy and aided in the mixing stage. The old timers used to put a small compatible star in with the flash in the salutes to help with the mixing. For what it's worth... WSM I had been wondering if this same principle would work in conjunction with a motor. Put the (2) powders into a cardboard casing with fuse and seal it (Leave a little empty space inside the tube so the powders have some room to move). Then attach them to a motor assembly that would slowly rotate/tumble them. The powders would be slowly mixed together inside of the complete assembly. Best part is, with an electric motor, you don't need to be there as they mix. You could set a timer or remotely activate it and come back when they are done.

xtr55 Posted January 11, 2012 Share Posted January 11, 2012 after a salute is built and is good to go, how sensitive is it? Is static still a major concern once it has been mixed, put into a casing, and closed up? Link to comment Share on other sites More sharing options...
dagabu Posted January 11, 2012 Share Posted January 11, 2012 after a salute is built and is good to go, how sensitive is it? Is static still a major concern once it has been mixed, put into a casing, and closed up? I consider it a loaded gun with no safety. Once mixed, treat the shell as if it is chlorate based and don't drop it or shock it. That said, I have NEVER seen a detonation that was NOT on purpose from a salute shell. They handle the lift fine so there is some proof that they are not too sensitive. -dag Link to comment Share on other sites More sharing options...

optimus Posted January 11, 2012 Share Posted January 11, 2012 so are there any precautions for static as far as handling a finished piece? Once it's all sealed up and there's no powder exposed, no. Link to comment Share on other sites More sharing options...
xtr55 Posted January 11, 2012 Share Posted January 11, 2012 Once it's all sealed up and there's no powder exposed, no. Thank you for the reply. That's definitely interesting. I would have thought it would still be an issue if the powder moves around in the casing and builds up charge or something. Thanks for the help and fast response!

MediumRare Posted February 13, 2012 Share Posted February 13, 2012 I don't know if something like Fe2O3 with fine magnesium would be considered flash, but it behaves like one.

patsroom Posted February 13, 2012 Share Posted February 13, 2012 I don't know if something like Fe2O3 with fine magnesium would be considered flash, but it behaves like one. Would anyone consider it dangerous? http://www.youtube.com/watch?v=pqQg4R8XRXY I truly do not understand why this subject was brought in to the forum in regards to flash Safety. It is post on youtube (Uploaded by Dornier335A on Aug 15, 2011) under the heading of Fe/Mg thermite. But to answer your question - Yes if the thermite was not handel properly it would be dangerous. But I do doubt that this comp has the sensitive of flash. Please slow down a little and consider what you are doing. The best thing to do is to do alot of reading first, think it out and if it still does not make sense then ask, I am sure there will be someone more that willing to help you in this field of pyrotecnic study...................

That has a profound impact for many people in this country who lived through that horrible day and its aftermath.
