Blambert Posted November 21, 2013 Posted November 21, 2013 I am a very newbee so please excuse any stupid remarks.I want to build a fountain with a small core hole for the pressure. Would it be a unsafe act if I took a rifle bullet as the core. My thinking is that it would give a tight pattern of sparks. I just want to make sure the brass / BP in the bullet will be a safe to try.
Bobosan Posted November 21, 2013 Posted November 21, 2013 No, Blambert. Would be a foolish thing to use a live round like that. A simple brass or stainless steel rod would be much safer.
chemtech89 Posted November 21, 2013 Posted November 21, 2013 I don't think I understand your question because I cant see a practical purpose of using a bullet as tooling for a fountain. Most people will hammer in a clay plug(which will become the top/ where the sparks shoot from) and then hammer composition ontop of that to fill up the rest of the tube. Then, another plug of clay is hammered in( the bottom). Finally you can take a drill bit and by hand, drill a passage through the top clay plug untill you reach the composition. This hole is where you ignite the composition as well as where the gasea and sparks escape. There is tooling specifically made for fountains/ gerbs which could illiminate the need to create a hole when your finished hammering/ ramming, due to the hole being created from the tooling when you ram your first clay plug. Now, if you ment using the bullet (without the cartrige) standing up and raming your clay plug around it, and after your done filling, remove the bullet leaving the cavity, I can see that as a practical use. However I assume this is not what you ment only because you said "BP in the bullet will be safe". Meaning the bullet is whole. I may have gone off explaining somthing you already knew. If thats the case i appologize. Could you perhaps draw a diagram of how you would use the bullet and/or explain it more in depth?
Blambert Posted November 21, 2013 Author Posted November 21, 2013 I do not want to put a live round. This would be a fired round shell with out the firing pin it. This would let the fountain shoot through the shell casing. I am trying to create a water fountain effect that would keep the sparks looking as pipe. It would not have to be a shell casing could be any small metal tubing, just needs to longer than the clay top. I included a file as a diagram
leedrill Posted November 21, 2013 Posted November 21, 2013 (edited) im still a little unsure even after the pic sorry blambert but it seems like you want to use the casing as a vent for the spars to come out of a. if you are using clay or grog to seal the casing in on top of the fuel then there is no need for it just leave it out and drill a hole through the clay end plug b. im big on the whole no metal ever even though it dosnt have any fuel packed inside it leave metal out of any building / casing unless powderd and mixed in the fuel c. remember that fountain comps and waterfall comps are basicly course mesh slow flash and will cause just as much damage as faster comps in thinner tubes pretty much all of the comps we play with have the ability to confine and cause damage this is why id suggest no metal casing to be used d. the longer you make the nozzle on a fountain the more will be burnt up before it exits the device and can be seen if its just a really thin spray of sparks you want maybe if you try it with a cardboard tube or just a smaller nozzle all different styles of spray can be achieved with the traditional fountain construction and some tweaking no metal needs to be used Edited November 21, 2013 by leedrill

Blambert Posted November 25, 2013 Author Posted November 25, 2013 Thanks to everyone, that is what I was looking for, I will not use them.
firestone Posted December 24, 2013 Posted December 24, 2013 I have a question that is pretty much unrelated, but since I can't start a thread I'm posting on this one. I have a TLUD stove that I made out of a 55 gal drum, it spits a nice flame for parties. I am wondering what the easiest way would be to get it to shoot sparks as well. I guess there are probably lots of ways to make sparks, so I am just looking for the cheapest. Seems like sometimes wood makes spars with agitation, so maybe an agitator would do the trick; or maybe something wedged between two screens in the chimney? This unit will burn for about 3-4 hours, although that sparks don't have to go that whole time, though it would be cool if they did. Any thoughts or suggestions? http://farm4.staticflickr.com/3785/11538964946_0c8a786d1b_m.jpg
ddewees Posted December 25, 2013 Posted December 25, 2013 (edited) Pay someone to stand there and kick the drum. Just kidding... have a merry Christmas. Edited December 25, 2013 by ddewees
firestone Posted December 25, 2013 Posted December 25, 2013 haha, actually not a bad idea, thanks for the response and merry christmas to you as well, some kind of agitator. of course an agitator could probably not do something like this http://www.oaklandmofo.com/images/burning-man-2009/fire-sparks-burning-man-2009.jpg
