"I prefer using a long quickmatch".I can just see it now,light the quickmatch,fiss,a few hundreds of a second later..WHERE'S MY HAND!!!!.Oh there it is in a million peices.Seriously though think about what your doing.As said,dismantling fireworks is not a good idea and is NOT common sense.(whats the point,its been designed and tested to do what your trying to archive anyway)

Please listen to the advice given,every composition demands the respect it deserves (thats common sense).


stay safe,(and keep your fingers) and stay green

Oh blur sorry that I am late. Though its a bit dangerous but I did the same thing when I did not have acces to much chemicals so I will tell you the answer which common sense says. I am not too good at all those confinement and burn rate but common sense just says that either there are impurities making it burn slow or either the tubing is too strong. Just use some better explosive(either made at home or emptied from firecrackers) and use a weaker tubing. Fill almost 2/3 of the tubing and use enough glue to ensure that those paper bits(used as caps) are properly fixed. Make a good fuse(I prefer using a long quickmatch) so that you dont have to make a big hole for it. These are just basics and dont need much knowledge about pyrotechnics.

Hope this helps. And let me remind you, this is common sense.

I could be wrong but the "long quickmatch" method he uses, i think, is different to what your thinking. If he ignites salutes this way and he has done so without injury i think he means that he makes a long quickmatch that can be ignited far away at a safe distance. You would need a long quickmatch though depending on the salute and this would probably be quite a waste of quickmatch but i geuss if the quickmatch was, for example, 5 meters long and he ignites a carboad salute from that 5 meters away it is then safe.

[karlfoxman]

A Salute????!!! 5 meters???!! WRONG! Im tempted to close this thread as its getting silly.

[portfire]

Quickmatch travels at 100ft per second (or at least the stuff you can buy,please correct me if im wrong) so 5m is 16.5ft per second,as you can see you'll need ALOT of quickmatch to be safe,its not worth thinking about.

[Zinginex]

I wasn't saying that that quickmatch fuse is a good idea but im just stating that it would be safe but stupid. And as i said it was only an example. "for example" 5 meters for a weak paper salute/firecracker which will hardly do any damage or make much of a report, no shrapnel. I would've said 20 meters but too be honest 5 meters for a VERY WEAK paper salute/firecracker, i think, is safe. Sorry if you don't agree but i don't want to turn this thread into an argument

EDIT: I'm just simply saying what can a WEAK paper salute/firecracker do to you 5 metres away?

Im surprised Karl that you havn't closed this tread earlier to be honest,iv seen treads like this closed after one reply.you do a good job though Karl .

Maybe he ment blackmatch (even then i wouldn't use it for a salute )

Might as well close it, because the OP doesn't know what quickmatch even is evidently. 5 meters of QM being lit would whip and blow quite impressively on it's own ! Likely more powerfully than his "weak salute".

[cplmac]

I think QM burns at 60' a second, still not a suitable fuse for handlighting. FT you got right, QM cutoffs make excellent flying fish fuses! That stuff does burn awful violent, the term fuse is somewhat misleading.

[king pyro]

What I meant was that knowing that a weaker tubing is needed if the tubing did not explode is just common sense. What knowledge about confinement and burnrate do you need to know that the tubing is too strong for the explosive? This is obvious that the tubing needs to be weaker in order to burst.
No one pointed blur wrong(blur I am sorry but I had to do this) but as soon as I said that the explosive can be emptied out from firecrackers, everyone became angry. I said this just because blur did this and its expected that he did this because he did not have much access to chemicals.
The quickmatch I was talking about should(according to me) be long enough to keep you at a safe distance. I dont like to use blackmatch because the one I make is not reliable. It extinguishes very easily. If anyone knows why please tell me.
And I agree that I am not much experienced. Having common sense does not mean that you are an experienced pyro.

Common sense is not common

It can be seen in this topic.


And Karl just wondoring why dont I see other moderators so active?

[blur]

I honestly dont care if people get all angered up over me emptying firecrackers, which i dont do anymore.

About the casing being too thick for an explosion, and it being common sense, well it was complete opposite. The casing was too weak which created no pressure within the tube (needed for an explosion).

[StevenRS]

He probably thought BLACKmatch was called QUICKmatch. Hehe... That could be a fatal mistake if he got it the other way....

About emptying firecrackers, everyone knows they use( at least were I live) flash powder, it just takes a long time to get it all out, gets clay in the flash, and is not worth the trouble, but there's nothing exceptionally dangerous about it. (If there is, please tell me, I want to keep my fingers)

[cooperman435]

Jesus Ive heard enough! I have to say something.

Do you guys just point blank refuse to read past posts and threads on all the issues you are discussing here!

1. Flash IS DANGEROUS. ( there are many posts explaining this and the reasons fo it)

2. Emptying fireworks IS DANGEROUS (because you dont actually KNOW what it is you are emptying or how it will react in larger quantities or with other compositions you may accidently or purposfully mix or contaminate it with)

3. BLACK match and QUICK match have some simalaritys but for the most importaint part of them which is speed of fire transfer along their length. Black match can be safely used in the right scenario as a delay fuse to ignite a device and retire to a safe distance quick match cannot and should be classed as an instant ignitior no matter what its length.

4. this post is the blind leading the blind the casing should be strongenough to contain the combustion but flimsy enough to disintegrate to avoid shrapnel. I chalange anyone to suply a container of any sorts strongenough to actually contain even a bp charge without bursting!

5. Firecrackers contain "composition" not explosives.

6. King pyro if you are still unable to produce reliable black match then I am seriously concerned with your knowlege about just general pyrothecnic practice. Saftey of others would be my bigest worry with the misinformation you are dispensing in this thread you simply do not know what you are talking about.

READ THREADS about all this and you will at least understand the problems have had to overcome to get results before you.

[king pyro]

Less pressure was either because you used negligible glue for the 'caps' or the tubing was leaking. If the tube would have been overall weak then though you wouldnt hear a boom but it would atleast explode, not fire coming out of sides...
Alright its good that you dont do this anymore.

AND I know the difference between black match and quickmatch and I use a lOOOng QUICKMATCH.
And flash is dangerous but if one takes adequate care its not that dangerous(atleast according to me), especially the one used in small firecrackers(I hope you emptied it from those small cylindrical ones).

I confess that I can not make good blackmatch(I can not even make an average one), and I would like to know the reason if anybody knows.
Those compositions are also low explosives so theres no harm in using the word explosives in general.

I would be intrested to see your working area, this way we can say if your being as safe a possible with this hobby. If you have quickmatch then im sure you can get hold of visco fuse?! Or are you making the quickmatch?

I always prefer making rather that buying. So I have made the quickmatch.
[I didnt even buy a weighing scale from ebay as you said; I bought it from a shop near my house; though it was a bit more expensive but as I said I'll think a few times before I purchase it through the net].
