Pyropow3r Posted December 15, 2009 Posted December 15, 2009 (edited) In this thread here i would like to see what you guys have made for your new years eve display (hens the NYE) Pics would be nice please... First i will start off with what i got -Gerbs Mainly charcoal based some using 6/3/1 Kno3/sulfur/Bp white star mix and combination's with charcoal and bp etc. -flares using white star mix very BRIGHT (The tubes burn away with the white star mix grain) -Sky Rockets (finarly)12 x 1/2 inch I.D 4 inch long sky rockets with report (Bp Report..... I don't like flash powder Expensive/hard to get chems/unpredictable..... Ive said enough) So here they are..... -Yes i do roll my own tubes -yes i do make my own fuses -Yes i do make my own stabilizing sticks (cut them out from plantation pine planks on a table saw) ......More to come i am still making more right up until NYE Show me what you got or are going to make pics would be nice please and thanks.....

Twotails Posted December 15, 2009 Posted December 15, 2009 Not much as of yet, made the DeathStar( >.< i have to finish it,) Just made two test batches of stars, Reynolds white glitter, and Yankees strobe(?) I have 200g red, yellow, and white Lance comps(part of them are going into the DeathStar) random flare compositions. A Christmas Present(smaller, backyard version of the deathstar) might attempt a beraq, and maby a few wheels. and various other things(waiting on my skylighter order) The DeathStar: basicly a set peice to end all set peices. its going to have a wooden frame( ball shaped) Two sections(top and bottom) spinning at diffrent rates(one clockwise one counter clockwise)(if i can get them to that is) it will be coverd in rice paper, powderd by a few(need to do tests) drivers, It will progress from small roman candle's positioned in the ball, to flares, then spinning, then reports, a large fountine, than a final large report/inner shell, that will propel stars outward. my goal is to make it look like the Deathstar from starwars exploding. gotta go finish the frame!
Gunzway Posted December 15, 2009 Posted December 15, 2009 Was there not already a thread dedicated to New Years 2010?
scarbelly Posted December 15, 2009 Posted December 15, 2009 Yes there was Gunzway: http://www.apcforum.net/forums/index.php?showtopic=4102
psyco_1322 Posted December 15, 2009 Posted December 15, 2009 Those are some nice looking rockets. Its really something to see someone going all out with everything "home rolled." Hope they fly good and make themselves worth the time taken to build them.
Updup Posted December 16, 2009 Posted December 16, 2009 Alrighty, those are some nice tubes indeed! My show consists of two shows, each show has it's main "packet" and a sub packet and 6 shells ranging from 7/8" salutes, to 1.7" can shell with flying fish fise and 5 salute inserts. Each packet it a neatly organized 4 fountains a creamora, and two flying fish fuse mines, the subpackets are two creamoras. In the first picture you can see my awesome homemade rack and the two show peices.http://i761.photobucket.com/albums/xx255/Updup/NYEShow2010001.jpgThis picture is one shows main packet in front, and the two creamoras to the left, one of my 1.7" can shells is on the right.http://i761.photobucket.com/albums/xx255/Updup/NYEShow2010003.jpgSome shells.http://i761.photobucket.com/albums/xx255/Updup/NYEShow2010005.jpgMy homade firing box that I will use to shoot the shows, 12 cues [=. For more info and picture on this, I've made a topic for it in the electric section.http://i761.photobucket.com/albums/xx255/Updup/NYEShow2010006.jpgAnd the show plan, Both shows combined is 3 minutes, I know... LAME but you got to star somwhere.http://i761.photobucket.com/albums/xx255/Updup/NYE2010.png
firetech Posted December 16, 2009 Posted December 16, 2009 I just hope that is real PVC...not the junk stuff thats not meant for pressure. I have had shells flowerpot in PVC and I really don't think it's pushing the limit at all. However you have salutes there, so be careful. Otherwise it looks good and I hope the best for your display. BTW, you're going to want to paste those spiked devices. The lift is going to burn the spiking very badly... At least wrap them in kraft.

Hope they fly good and make themselves worth the time taken to build them. Yeah Ive been using this same type of design for years never had one fail yet i guess you can say they are a tried and trued tested design. Ive also been rolling my tubes and fuses since the dawn of time so now i got a real nack for it. I can make these things real quickly..... I guess you could say i am a qualified Chinese factory worker.....
psyco_1322 Posted December 16, 2009 Posted December 16, 2009 I would be more worried about those unpasted shells getting fire leaked into them. You could be looking at flower pots in each gun. If anything, tape them up. You have plenty of time to paste them before New Years. I don't think they make cellulose core PVC in that small of diameter. Its usually the larger stuff that's used for drainage. Most of his mortars are boxed in with plywood, and those shells shouldn't build much pressure. You should be fine with that set up. Just make sure you stake down your rack, else it will tip over. In the event it does tip over, make sure you have the edge pointed to the crowd, not the side. If it falls over, it will shoot sideways instead of at the viewers.
Updup Posted December 16, 2009 Posted December 16, 2009 Good advice guys, it is real PVC, rated at about 350 PSI, and the salutes are 7/8" ball shells filled with very fast black powder, shot from my little morter. As far as pasting the shells goes, I really should have, and I might still do so, but I'm not worryed about flower poting because the shell under the cardbord is pasted up real good, I needed a tighter fit in the moters so I added the spiking and tube layer. I will stake the rack down, I still have to screw in my metel loops on the side in which I can drive some rebar a few feet in to the ground, thus making the rack untippable. Anothing thing that the rack is missing right now is a bottom, should I bother?
psyco_1322 Posted December 16, 2009 Posted December 16, 2009 A bottom would be nice. It would keep crap out of it and keep the tubes from falling out if they are loose. That makes a lot more sense that you say thats just bulking material for your shells. If they are good and pasted under that, they should be good.
Ralph Posted December 16, 2009 Posted December 16, 2009 Anothing thing that the rack is missing right now is a bottom, should I bother? Safe mortars
scarbelly Posted December 17, 2009 Posted December 17, 2009 Generally people will say that if you're using PVC, you should bury your mortars in sand. If you dig a trench and bury your entire rack, that should work. I doubt that it will be too big of a deal with shells that small lacking any flash or whistle, but it's better to be safe than sorry, especially considering it's such a simple thing to do. Even better would be to find cardboard, HDPE, or even fiberglass mortars, but i doubt you're gonna want to hassle with that at the moment.
Updup Posted December 17, 2009 Posted December 17, 2009 Okay, Ralph, are you saying that I need to get safe morters? I know that PVC isn't ideal, but Each tube is wraped in quite a few layers of super strength ducktape all the way to the point the the tubes pop out the top, thus making them stronger and reducing shrapnel, now, i hate to get defenceive because, you are right, and I should switch to HDPE or fiber glass. You will be happy to know that they are on my X-mas list, and also on my next order list . Burying them would be good, but I don't think I'll have that much time, as I think I'll drive to the site on the night of, and basicly have a quick ten minute set up and shoot the show, and my crowd (however small) will be waiting. I'll be 100' away from the rack, and the onlookers about 120', but I think I'll put somthing bulky inbetween people and rack. I Think I'm going to paste over that spiking any way, because I'm not stressed for time right now and I could do with a bit more bulkyness. I think I'll cut out a base that I can quickly screw on or somthing.
psyco_1322 Posted December 17, 2009 Posted December 17, 2009 I think he is saying that it would be safer to have a base. If you plant the rack on anything that doesnt let the mortars rest solid against the ground, like grass, when fired they will shoot in the opposite direction of the shell. This will cause the shell to not fly as high and possibly result in low breaks.

Ventsi Posted December 17, 2009 Posted December 17, 2009 Okay, base I will add Just FYI, DuctTape is not going to do much to prevent a tube thats already planning on going berserk on you , you'd be better using something that had a better adhesion/tensile strength such as Gaffer tape or fiberglass reinforced tape. Sure if you put enough Duct tape on there like the Mythbusters did it'd be safe, but I'm just being practical here.

dagabu Posted December 21, 2009 Posted December 21, 2009 http://www.pyroboom.com/index.asp Kid, thanks for the link, I misplaces mine. Best prices so far, HDPE, cant beat it. D
usatrapper Posted December 22, 2009 Posted December 22, 2009 my friend was at a shoot when a 5'' ball shell flowerpotted in a PVC mortar.... 2 people died...
firetech Posted December 22, 2009 Posted December 22, 2009 My condolences for the families of the victims. However I would consider that murder. You have to be seriously f#cking retarded to load a 5 inch shell in PVC. Do you know why it flowerpotted? Because it was made by the same guy who decided to throw it in a PVC gun.
Updup Posted December 23, 2009 Posted December 23, 2009 my friend was at a shoot when a 5'' ball shell flowerpotted in a PVC mortar.... 2 people died... Ouch, thats not cool .... Just to prove somthing, it takes about 50? PSI in a potato cannon to shoot the item hundreds of feet. The pipe I am using is rated for 400 psi, the shells are 1.5" shooting about 100 feet up. That being said, I Am going to do everything to ensure safty.
Mumbles Posted December 23, 2009 Posted December 23, 2009 Step one to ensuring safety would be replacing the PVC with fiberglass or HDPE as soon as possible. Since it seems like you have your mind set, at least until new years, do everyone a favor and put some sort of barricade between the rack and the audience, or better yet take them out of the rack and bury them all. We've all been in your situation where PVC was so convenient and there. No matter how safe you think you are, it is still PVC. It becomes even more dangerous in the cold, where it gets more brittle. It's not always the pressure, as much as it's the shock of lift or a flowerpot.
dagabu Posted December 23, 2009 Posted December 23, 2009 Ouch, thats not cool .... Just to prove somthing, it takes about 50? PSI in a potato cannon to shoot the item hundreds of feet. The pipe I am using is rated for 400 psi, the shells are 1.5" shooting about 100 feet up. That being said, I Am going to do everything to ensure safty. The brisiance of black powder is pretty minimum but in the case of a flower pot, the combined contents of the shell increases the pressure but also the brisiance within the mortar. As Mumbles said, the degree of brisence the PVC can take decreases as the temp drops. 400 PSI is static pressure, dynamic pressure is an entirely different thing. D
Updup Posted December 23, 2009 Posted December 23, 2009 I might have an alternitive, on the way up here I stoped by a fireworks store (who here can resist?), and got some reloadables, and three morter tubes, I'll have to see it thay will fit, and even if they do I'm still one short (I brought one paper morter). I'll use paper if I can, and assuming the shells don't fit my paper morters I'll put somthing big and heavy inbetween me and rack, if I find a flower pot around here i can plant the rack. But this is really the ONLY time I'm going to use PVC, I would have gotten HDPE but simply ran out of time. Also, assuming the weathers nice it's fireworks night tonight YEA!
