hashashan Posted April 26, 2008 Posted April 26, 2008 Hi, another 3"er stars are C6 to redburst is H3 on puffed rice, 2.5 grams Mg/KClO3 flash burst the shell was pasted with 3 layers(the 3 strip method) of fiberglass reinforced gummed tape http://www.apcforum.net/files/myshell.JPG PS. the small one is the 3"er (duhh)
pudidotdk Posted April 26, 2008 Posted April 26, 2008 The break was unsymmetrical and from the look of it, it must be the pasting. The colorchanging was a bit off, but it gave a strobe-like effect. The shell was nice though, and the red was excellent, which formula did you use?
FREAKYDUTCHMEN Posted April 26, 2008 Posted April 26, 2008 3 strip pasting method is only usable for gummedpaper or pasting with kraft paper. A flash booster is also not nessesay when useing H3 as burst charge. If you use fiberglasstape, than tape it in almost one piece. The red looks great!
hashashan Posted April 27, 2008 Author Posted April 27, 2008 The red was as simple as it gets, the Sr(NO3)2,PVC,Mg (binded with PVC+THF) I have to disagree with you about he symetry of the break. The stars were a bit different in size so It may look unsymetricl but as I rememeber it it looked pretty darn symmetrical to me. now about the 3 strip method: Wat method should I use?
oskarchem Posted April 27, 2008 Posted April 27, 2008 Humm... I'm very interested in this composition, could you give us the exact amounts?please. Because I am having difficulty to find color composition with only PVC as chlorine donor.

Flying dutchman Posted August 18, 2008 Posted August 18, 2008 WOW,the red was awesome!!!the best shell i have ever seen so far. 20/20Really spectacular,congrulations.
Yankie Posted August 31, 2008 Posted August 31, 2008 Nice red, could the Mg powder be substituted with MgAl?
Miech Posted August 31, 2008 Posted August 31, 2008 Probably. You'll have to ajust the ratios in some amount to optimize color and burning caracteristics when using magnalium, since it reacts slightly different.
hondo Posted November 21, 2008 Posted November 21, 2008 hey looked good to me, I kind of thought the burst altitude was a tad low for a 3 inch shell,
swervedriver Posted November 28, 2008 Posted November 28, 2008 Beautiful! H3 burst against Chrys 6 stars? Did I understand correctly, or is C6 something else?
swervedriver Posted November 29, 2008 Posted November 29, 2008 Well, it looks like he's not been back in a while. Maybe someone else can offer me help. The reason I asked this question above, is that if he did use H3 burst with chrysanthemum 6 stars, is there a certain way used to keep the chlorate from touching the stars? Simply enclose a tissue bowl well, or some other method? thanks for the help.
TheSidewinder Posted November 29, 2008 Posted November 29, 2008 Yes, you can use a tissue burst bag for added safety. But a lot of folks don't worry about the minimal contact and don't bother using them.
