fast visco fuse

Recommended Posts

Question for ya'll I was wondering if one made a slow flash powder comp and used it in a visco machine if the resulting fuse would turn into more of a det cord or a quick match???? I have not tryed this yet but figure i ask before i go doing this I do know all the warnings about flash powder. if anyone has done or tryed this yet please let me know thanks :D

I'm not entire sure, but I would think it's generally a bad idea.

Besides the friction and other hazards while making the fuse, you'll end up with something like an explosive wire.

Det cord is tubing filled with pentaerythritol tetra nitrate.. What are you trying to accomplish ?

Sounds like you want to be creative :)

 

I assume it would go bang considering on the flash powder used. But that's hard to determine considering not many people have done it.

 

Try taking 1-3g of flash and, being very careful try it out and tell us what happens!

I would abandon the flash idea and look into sticky match with regular BP.

i tried making my own version of sticky match with my granulated bp and it was pretty much a small explosion it happened so fast i dont even know if it would have lit a fuse on the other end of it i never tried it again since then im guessing either my blackpowder was too fast or i used to much also i used masking tape instead of clear tape

To my experience, it sounds like you had air-pockets or similar; that the BP was not packed good enough.

Sticky match is supposed to be lightning fast. I believe air pockets are one of the characteristics that allow for such fast burning.

Mine was more of a explosion not like quick match more like a firecracker sound

Sticky match burns around 80-90 ft per second. We use it all the time for finale racks and it is very reliable to ignite everything. It is not packed tight at all, it is just a trail of finely grained BP on clear tape.

Make a trail of BP down the middle of the tape, then fold over the one side of the tape then the other side.

Commercially available sticky match has a trail of BP in the middle of the tape with a narrower length of tape centered over the BP. The BP trail is protected by tape on both sides, while the edges of the sticky match have exposed tape so you can stick it to things. In practice, the leaders for whatever you are lighting are taped inside the sticky match by folding one side and the other as the post above describes. Sticky match makes fast work of fusing set pieces and finale chains. It does not do well if it gets damp, so take measures to keep it dry or use another method if it is raining when you set up the show.

If you can do it well, you'll probably end up with something resembling flying fish fuse. In essence, that is what FF fuse appears to be. They're likely very energetic, high metal, color compositions which tend to resemble slow flash type mixtures.

That would probably be a very very slow flash mix. Like KNO3:Al 1:1 or something.
