NeighborJ Posted December 16, 2017 Posted December 16, 2017 (edited) Sondre, I'm not shure I follow what you are saying. You tested a damp BP comp wrapped in plastic wrap? Instead of using milldust, I tried using the fines from granulating BP which pass thru a 40 mesh screen. It created a micro granated powder which is fine enough to allow the plastic to stretch but it flows without making a mess. Edited December 16, 2017 by NeighborJ

I used milled BP before and it started to fall out after a while so i started to prime the tip. but i was happy with the result i got with the method i tested so any prime is not needed.
Simoski Posted December 24, 2017 Posted December 24, 2017 @Sondre, well done! The best solution is the simplest, and this sure is simple, again well done! 1

stix Posted December 25, 2017 Posted December 25, 2017 This composition made a really nice fuse. Flamethrowing black powder 74.30% Potassium Nitrate21.80% Charcoal3.90% Sulfur Sondre, I have to say there is something mesmerizing about watching that video - can't help watching it.... ooohhh shiny!! I couldn't work out if the video was your own or posted from somewhere else - I assume it was yours, but I guess it doesn't really matter. So was the composition formula posted above the one used - or one you have tested and works well?

It was not the composition i used in the video but i tested that composition after and it makes a beautiful fuse with alot of sparks.
stix Posted December 25, 2017 Posted December 25, 2017 Ok, thanks Sondre. I don't have a great need for visco and the like, but that method appeals to me. I wouldn't be making a lot, so the burning of plastics from an environmental aspect I can live with. I've got a couple weeks off over Xmas, so in the interests of science I may have a crack at it. I just had a look at my reserves of "cling wrap" and I've got the usual "glad wrap" and a generic brand that actually says "super stretch". I just did a simple test rolling some. There is a good amount of stretch and then it just "stops". I think it will be ok. As with most things, there is a technique, and it doesn't come as easy as it looks. Cheers. 1
Svimmer Posted January 17, 2018 Author Posted January 17, 2018 Here is some time fuses i made https://www.youtube.com/watch?v=7pYPL2fW8xo
OldMarine Posted January 18, 2018 Posted January 18, 2018 Might want to work on that one a bit more before committing it to a shell. Seemed a bit erratic. 1
Svimmer Posted January 18, 2018 Author Posted January 18, 2018 (edited) Might want to work on that one a bit more before committing it to a shell. Seemed a bit erratic.Yeah it is not something i would put on a 6 inch shell. I use it for small shells. If i put black powder on all layers then it burns more consistent Edited January 18, 2018 by Sondre
Mixer Posted January 18, 2018 Posted January 18, 2018 (edited) It looks as though the melting plastic is stifling the flame - not good. Edited January 18, 2018 by Mixer

Ionforbes Posted October 10, 2020 Posted October 10, 2020 Sorry for reviving this old thread, but does anyone know what the method was? Currently I'm having to make fuses with sugar and saltpetre that go bad after a day or two but the video is private and I can't buy thee proper visco stuff where I live.
Richtee Posted October 16, 2020 Posted October 16, 2020 So Captain Planet will give us his blessing? It's got to be better than my idea of using juvenile bald eagle quill feathers stuffed with BP and covered with a heavy coating of oils derived from baby seal blubber. Sometimes I’m grateful for the old threads being dug up. that’s a hoot!
willowchar Posted October 28, 2020 Posted October 28, 2020 Can anyone recall the method used in the video. Unable to view the vid. Guess its too old 1
BetICouldMake1 Posted October 28, 2020 Posted October 28, 2020 I believe it was something like rolling up bp with plastic wrap and twisting/stretching it out into a thin fuse.
SeaMonkey Posted October 29, 2020 Posted October 29, 2020 Lonforbes, (my apologies if I've misinterpreted) Many thanks for the video link. The channel is one that I hadn't yet discovered and it has some very interestingsubject matter.
SkyArt Posted November 2, 2020 Posted November 2, 2020 My apologies if this was already discussed, but something that may help is milling black powder without a binder (such as dextrin or red gum), wetting it, and then crushing it before "wrapping it."
Jazzbass5 Posted November 2, 2020 Posted November 2, 2020 Okay, so I made a few batches of the Kno3/sugar/yarn fuse a week or so ago it tested okay but just read that it doesn't store well? Is this true?
Ionforbes Posted November 2, 2020 Posted November 2, 2020 I've found you can store sugar fuse reasonably long (a few weeks at least) if you dust on a light coating of anhydrous coppper sulphate. Best to just make it within a day or two of use.
Arthur Posted November 3, 2020 Posted November 3, 2020 Compounds with sucrose do absorb moisture so are best kept in a tin or jar with dessicant and lid. 1
WRAITH Posted February 13, 2021 Posted February 13, 2021 Get some tissue paper (wrapping type & not the ones you grab when you have the corona virus), cut strips of around 2 inches wide & your desired length. Grab a glue stick & nearly cover the paper that's facing you with it, then get some black powder, place it in a small container & sprinkle a line down the centre of the length of tissue paper then fold in half (not lengthways but top to bottom, pressing down on the half folded paper with black powder now running lengthways in-between the fold. Wait for it to dry a bit, then run your glue stick only on one side of it & roll up at roughly a 45° angle so it slightly twists lengthways. Let fully dry & twist a bit more then it's ready to use.
