# Official Fuse Thread #

But that counts for every single fuse that is made.. Everytime a dumb kid produces a fuse, whether it is according to grim's way or my way there is a chance of that thing burning way to fast. However the dangers are only stated whenever i post something which is to my thinking "nitpicking". I just posted a plan or a way that works for me.. anyone willing to try it out TEST IT FIRST!

[hellsgateman]

To all my fellow anarchists stuck in this hellhole of a state p.a. .
i have some news if you dont have time or, just want quality
fuse just go out to one of those army nave surplus stores and ask for cannon/saftey fuse. ive found the poor pethetic basterds working there are so under paid they dont check ids or even ask for age(good for us) just remember if you need fuse but dont want a trail just swallow your pride and ask for it .

[fenderbender48]

Absolutely right. Store-bought fuse is best, period.

Personally, I have used a lot of fuses, and BP in any kind of tube sounds dumb to me. Good call, grim. I once used smokeless (4895 to be exact) in a rolled up business card and it burned very slowly, but still, its a generally bad idea.

If using the aluminum foil thing works for you, go for it. Unfortunately though, there are people here that are pretty much the definition of unsafe. Again, I have to agree with grim on not telling people something they can easily screw up.

Use visco or cannon fuse, they work well. I personally can't stand blackmatch, it's too damn fast. If you are a hands-on guy like me and want to make your own, well, right now I'm trying the KNO3 and sugar mix, but i put way too much sugar in and basically what I got was rock candy that smells like cat piss. I'm trying again, and I will let you know how that goes.

Visco is cheap, and people don't usually ask questions. Look into it.

I was wondering if anyone ever used the model rocket fuse that use the electric pushbuttons? And if any of you have have you rigged up a timer and capacitor to one?

[hellsgateman]

yhea i did once but there is a good reson you always see terrorist,bank robbers ,enthusists using fuse or a trip line.
for it to work you have to physicly be there and if your like me youl end up pulling shratnull out of your limbs for days just spend some time and get tripline if you need plans just pm me

I thought this was a fuse thread,is a trip line/wire trip a fuse? well it's part of a fuse! Anyway checkout the Department of army field manual-FM 5-31 BOOBYTRAPS,from 1965 and a great read!I've got an original.

I think this started going south when the word tripwire was mentioned, making a perfectly innocent Ignitor into a WEAPON.

Personally, I don't understand why everybody doesn't just use Nichrome Rocket Ignitors, The fact is, they are safe and reliable, and if the user is cautious (which i would hope they would be while using ANY explosives) then they are probably safer than fuses.

Think about it this way, IF the danger of stray mobile signals etc was that real, do you think they would put them in Childrens rocket kits?

No

Try it, absolutley brilliant, all you need is a roll of electrical cable and you can have more distance before you ignite, and as soon as you ignite, it explodes, meaning there is Minimal danger of say, somebody walking into the blast area while the fuse is burning!

[john lee]

I think i've already said this,but in the UK 72MHz is used by the MOD! You need the ok from them to use it. The chances of it being set off by someone else are very low.

I've made expedient fuses from all sorts of indigenous materials. Here's a couple that come to mind:

-Take a sheet of tissue paper (the kind that comes in a shirt box, NOT toilet paper). Cut a strip about 2 inches wide. The length is your choice. Take a gluestick and draw a line straight down through the middle of the tissue paper from one end to the other. Now sprinkle either gunpowder, black powder, or powdered match heads along the adhesive glue strip. Make sure there's no gaps. Twist the prepared tissue paper into your fuse. That's it.

-For long delay fuse I use a stick of incense. You can experiment with it to determine the timing.

-I also use cigarettes as time-delay fuse "enhancers". A cigarette will add an additionl 5 to 7 minutes delay to a traditional firecraker fuse. Just poke a hole in the cigarette near the filter, but still in the tobacco. Use a needle and poke it all the way through. Light the cigarette and insert your firecracker fuse through this hole. You've got 5 to 7 minutes to flee the scene before it goes off. I've had tons of fun with this idea, just in time for Hallowen.

-This last item is a rather exotic idea, but I've used it to experiment with time-delay fires. It uses a soldering iron and a light timer--the kind you plug into a wall, then plug a lamp into it so it turns on at a predetermined time. Instead of a lamp I plugged the soldering iron into it. The tip of the soldering iron rests on your combustibles (newspapers, etc.). Match heads can assist in the ignition.

Just some food for thought.

I thought i would say how i make my black match,it's not the same as other ways i've seen it made,but it works and that's all that matters.

You will need-
100grams greenmix b/p,does not have to have been ballmilled.
10grams dextrin.
50grams KNO3.
cotton string.
water.
A bowl.
A teaspoon.
Somewhere safe to hang the fuse when drying (outside is best)
Pegs to hang the fuse.

First only use 2-3 threads from the cotton (garden type) string.
Cut the string to a size that can be hung to dry.
Soak the string in a mix of 50grams KNO3 and 150ml of hot water.
Hang the string to dry.

when the string is dry add it to a mix of 100grams of greenmix b/p,10grams of dextrin and water to make it look like soup,it must not be too thick,if it is then add more water.
Use the spoon to crush the string into the mix.
Now pull out the string and with the back of the spoon,run it down the string once only,this will remove any unwanted mix.

Hang the string to dry,it should take one-two days to dry,depending on the weather.
That's it,you've now got the same fuse i use with i can't afford to buy visco.

NOTE It's best to cut the fuse to the size needed before storrage and not to bend it.It will still work,but the burning time will change,this is mainly due to loss of the outer b/p cover,but as the string has been pre soaked in Kno3 will not go out.

Is it possible to make a completely waterproof blackmatch by coating the fuse in something?

Also are there any good tutorials of how to make an average ball mill? It is complicated for me to get one here in Australia without having to pay $120 for it.

Blackmatch can be coated with Nitrate dope,this is sold in model shops or can be made with guncotton and acetone,some use ping pong balls.I would not say that it makes the fuse 100% waterproof,but i have seen the fuse working under water using the Nitrate dope.

There's some good instructions on ball mill making out there,but would think it's best just to buy one,unless moneys a problem.Most chemicals/metal can be bought permilled.

You can waterproof something by taking ping pong balls(or some kind of thin plastic) and soaking it in acetone until it becomes a gooey mess on the bottom with acetone on top and then letting the liquid acetone evaporate or by pouring it off and the resulting gooey mess can be put on a fuse to somewhat waterproof it.

Not all ping pong balls will work.
Test the ball by burning a small amount,it should burn very fast with an orange flame,they also have a strange smell.
Cutup two balls and add them to 100ml of acetone,it can take upto a week for them to desolve,if the mix is to thin add more cutup balls,for fuses it should be like varnish,if you want it for a binder it will need to be thinned down.
Making guncotton is very easy.All you need are-
30ml Sulfuric acid 90%+ (uk go for a brand called SHIFT-IT 94% and it's clear)
25grames potassium nitrate.
2grames cotton wool (uk ASDA is cheapest)
If you need to know the rest please pm me.

[Belgarion]

Thanks John I will try the ping-pong ball Nitrocellulose Lacquer method first then try the gun cotton if that doesn't work.

[deadlyvenom]

why don't you just take cotton string, coat it in wax then dip the vary tip in gas or something? that makes an ok fuse but it works for me.

That would not work, cotton will not burn on it's own.

[X-ray Cat]

If its trinitrate it might work lol, dunno how fast it would be though haha

[deadlyvenom]

ya but surprisingly it does work, but it burns not slow but not fast either so i guess it is a medium speed but i dip the both tips of the wax coated string in gas so it gets a burst wen it starts and ends
