artificier Posted February 20, 2006 Share Posted February 20, 2006 I will buy spanish shell to make this firework.I used safety fuse.I filledthe shell with my special report mixture (70% KClO4 + 30% AL = standard flash powder)but i will mix flash powder with smokeless powder 50/50 to make the loudest flash powder.

justanotherpyro Posted February 21, 2006 Share Posted February 21, 2006 I have run into a problem. I have an 1/8" thick spiral wound tube for a 3" shell. I am trying to glue the flaps down flat onto the end disc holding the time fuse. Pictures 3&4 of the 3" insert shell are exactly what I am talking about. The paper is so thick that the flaps won't go down flat. I was thinking of soaking the flaps in wetted down PVA glue or maybe wheat paste untill they are workable. A ten pound weight won't even push them down sufficiently. Does anyone have an idea? Link to comment Share on other sites More sharing options...
PyroPicasso Posted February 21, 2006 Share Posted February 21, 2006 I use a mallet to ram them down a little, but don’t mess up the fuse. Them I apply glue and put the shell in a vice and let it dry make sure not to crush the fuse in the vice. Link to comment Share on other sites More sharing options...
TheSidewinder Posted February 21, 2006 Share Posted February 21, 2006 justanotherpyro, I looked at pics 3 & 4. Then I re-read your description. It sounds like you are cutting the flaps on the 1/8" tube itself, and not in the paper around it? *IF* that's what you're doing, that's not the way it's designed to be used. The end disc is designed to be glued onto the *end* of the 1/8" tube, not inside of it. Then you use 70 lb Kraft, two turns around the shell, and long enough to make the flaps you see in pic #3. Cut the flaps in the 70# Kraft, then fold them as shown. If this is *NOT* what you meant, and you are using some form of Kraft paper around the shell like in the pics mentioned, then I can't see how you could even FIND paper thick enough to cause the problem you're describing. Can you elaborate? M Link to comment Share on other sites More sharing options...
justanotherpyro Posted February 21, 2006 Share Posted February 21, 2006 What you are saying sidewinder is good idea. The tube is not designed for anything but to hold paper towels. I will give that a shot though after I procure another tube. Link to comment Share on other sites More sharing options...
TheSidewinder Posted February 22, 2006 Share Posted February 22, 2006 Sounds good. One other thing you can do, if you have plenty of paper, is take 3 or 4 turns of 70# Kraft around the tube and paste it on heavily but evenly. Let dry, then trim off excess even with tube end. This will reinforce the towel tube. Glue on the end disk, then paste the shell with the larger pieces of Kraft to make the flaps like in the pics. Spike it, if and however you wish. Post pics if you launch it. M Link to comment Share on other sites More sharing options...
justanotherpyro Posted February 22, 2006 Share Posted February 22, 2006 Funny you say that as I will be getting a camera soon. Although my pyro is on hold because it is winter, school load is heavy, and I have no money for chems. I am experimenting with how to make things for when the above problems are fixed. The beauty of the tube that I have is that it needs no reinforcment for the sides, only for the caps. Schools and offices have a cash of tubes thrown away every night if they use the older paper towel dispensers. When I happen to get my camera I will gladly post some pictures.

artificier Posted February 22, 2006 Share Posted February 22, 2006 I use chrismas ball to make shell and i fill flash powder and i wrap all with 5 layer of craft paper.work well !! Link to comment Share on other sites More sharing options...
Mumbles Posted February 22, 2006 Share Posted February 22, 2006 You need to move beyond just report shells. Using plastic on them is just asking for trouble as well. The shrapnel will be a lot sharper, and fly a lot farther with it. Link to comment Share on other sites More sharing options...
artificier Posted February 22, 2006 Share Posted February 22, 2006 Yes that's righ is a real danger about shrapnel but heavy or thick plastic chrismas ball is more safe than glass chrismas ball or the best shell is polyethylene hemisphere or for small shell is ping-pong ball with lot of kraft paper or kraft tape is the cheap way but normalyi use traditionnal paper ball.

Guest pyrokid00000 Posted February 23, 2006 Share Posted February 23, 2006 I found a video of a 48" shell. These things are truly breath taking. http://www.break.com/index/48in.html Link to comment Share on other sites More sharing options...
evilgecko Posted February 23, 2006 Share Posted February 23, 2006 Making my first 3 inch shell at the moment. Biggest thing I've done before is a 1-1/2 inch mini shell. Im making a dummy shell first, except its loaded with actual stars and break (but no fuse). This is so I can make sure its flameproof. I've finished spiking just gotta wait till the weekend when I can cook up some flour paste. Link to comment Share on other sites More sharing options...

Givat Posted February 25, 2006 Share Posted February 25, 2006 My first italian shell:6 c"m OD9 c"m long150 gram aqwa_po stars. http://hozt.net/thumb/20060222155737363214-custom.jpghttp://hozt.net/thumb/20060222155737288086-custom.jpghttp://hozt.net/thumb/20060222155736837568-custom.jpg the movie:http://www.pyroland.net/quest/movies/italian%20shell.wmv BTW, the shell case weighed about 80 grams - is this sound logical for this measure of shell?

Mephistos Minion Posted February 25, 2006 Share Posted February 25, 2006 What kind of paper have you used for the casing? The orange coloured stuff. Nice video btw, and is tat a hand rolled Spoulette as delay? Link to comment Share on other sites More sharing options...
Kilo_G Posted February 25, 2006 Share Posted February 25, 2006 Yofi Yofi. Nice shell. What I don't get is how Mosad doesn't come chasing you down when you light shells. Ever get any problems in Israel from this? Link to comment Share on other sites More sharing options...
Givat Posted February 25, 2006 Share Posted February 25, 2006 The orange paper is "Bristol paper". Since I can't get any cheap kraft paper here I use this paper mostly. Yes, the Spoulette is hand rolled. Kilo_G, I guess you don't really know what is the Mosad in here. Little children playing with fireworks won't really bother them. The police is more of a problem for this hobby, like in most of the countries. I guess that if I would play with big amounts of HEs near settled areas, so maybe then the Mosad will notice me.

Pretty green flame Posted February 27, 2006 Share Posted February 27, 2006 PGF, what size were those shells??Coz they dont look very impressive.small, 2" canisters. Btw, please say why you think they don't look impressive, constructive critics are welcome not just "they look like crap" or similar, post like these won't help me improve things. So what is is, the spread ?? Link to comment Share on other sites More sharing options...
Mephistos Minion Posted February 27, 2006 Share Posted February 27, 2006 I think alot of the problem lies with the camera, I know how poorly they can capture a firework. The spread would have looked alot better with a larger tail. I know it is hard to achieve a symetrical break with 2" canister shells, I see many asymetrical breaks even at proffessional displays using them. How were the shells spiked? Have you got a photo of them? I love in the vido how we can see the little flame retreating from the lit mortar Link to comment Share on other sites More sharing options...
