This instructable describes how to build a simple fuser to quickly and efficently make hundreds of feet of pyrotechnic fuse. It requires very basic materials and construction skills, and the entire process only takes a matter of hours to get hundreds of feet of fuse.
I would like to give credit to both united nuclear and pyro universe, because this design improves on and modifies both of their ideas and techniques. This project will have much use in my other projects requiring fuse, and as every pyrotechnic knows you can never have enough fuse.
This fuse burns at appx. 1 in. / sec

The parts for this project should be relatively cheap because most of the items can probably be found around your house. The black powder (gunpowder) is the only thing you might have a problem getting your hands on, but it shouldent be too hard if you know where to look.
Parts:
1. Old tupperware container (medium sized)
2. Black powder (Can either be bought at gun stores, with proper id, or made in my tutorial http://www.instructables.com/id/EEXOON4E1HEPA8KQNM/ )
3. 1/4" Wooden dowel at least 2 feet in length
4. Dextrin, A powdered pyrotechnic glue (Can either be bought on e-bay, or made, Ive never made it but the good folks at pyro universe say "To make dextrin, spread an entire box of corn starch out on a cookie sheet and cook it in the oven at 400° for about 2 hours, stirring it every 20 minutes or so with a spatula to keep it from burning. When it's done, it will be light yellow/gold in color.")
5. Scale
6. Rubbing Alcohol
7. Devcon weldit all purpose glue
8. 1/4" and assorted smaller drill bits and a drill
9. Old clothes (or some type of overcoat), latex gloves, and eye protection (Optional)(This project is messy)
10. (2) Spools of cotton twine, make sure it has nothing else in it wax, etc. (to do this take a sample 3 in. piece of it and burn it, if it contains wax or something else it will drip, if it dose not drip when burned it is good)
11. Old scrap wood, a 3 foot long 2x4 would be good enough
12. Saw
13. Hammer and nails

But aside from that, nice instructable, very enjoyable.
such an environment may be found in the highly confined hole that a fuse must burn through to reach the insideds of a firecracker
also, have you ever just used potassium nitrate for the fuse, with dextrin? and if so , what are portions you should add inorder to aquire a a fuse that is capable of supplying its own oxygen source for burning.
so far i have not been able to make a fuse, other than with matches ( with the fuse being about as dense as the actual match heads due to the large amounts of match powder used), that could burn through confined holes, and thus have wasted alot of precious resorces in making these fail matches.
This might be helpfull to more people than just you, but you are the only one asking this question it seems.
Most (If not all fuses) covered here and in anarchy cook books follow this or similar method. The problem with these methods is that it just burns on the surace, thus when pushing it trough a tight hole, burning will stop at the hole. The two strings twisted together is about as close to a solve I have seen...
The method I use is simple:
Get some rice paper and cut to length if you prefere, but keep it a few centimeters wide (An inch or two wide).. Now coat the ONE SIDE with the blackpowder-water mixture as mixed in this instructable (it works) and roll the rice paper up as tightly as you can keeping the blackpowder in the inside of the roll (Much like roling a joint)...
Now coat the exterior with the blackpowder mix aswell if you deem it necessary. Hang to dry..
You can also use that thin material used to cover up wounds before a bandage is applied. Just remember to use a single layer, this seem to work the best.
Hope this helps some of you folks. Cherz
i cant believe i overlooked that!
anywho, explosives galore
Nice =)
