jrin0630 Posted January 5, 2017 Share Posted January 5, 2017 Very nice shells. What do you use for breaking them? Link to comment Share on other sites More sharing options...
ExplosiveCoek Posted January 5, 2017 Author Share Posted January 5, 2017 Thanks, I really focused on hard, strong breaks this time. It required a lot of testing and repriming of stars before. I used MCRH 1:5 with assisted Apertura flash on almost all breaks, one of the 5'' had 7/3 in it. Apertura is more forgiving, but requires more pasting than other flash boosters. 3'' 6 g 6 layers pasting4'' 8 g 6 layers5'' 12 g of 7/3, 4 layers pasting. Others 16-18 g apertura, 8 layers pasting. I'm still convinced that by using 7/3 I can use less pasting, which is something I prefer. Based on this vid, and previous results, it should be doable. But still need some more tests.6 the big orange + FeTi willow had 8 layers pasting, the white willow 10 layers. Both had 30 g apertura. I don't know why the white willow's break was so ugly, maybe I didn't fill it properly with MCRH and the stars started to shift a bit. Previous shell's made with these stars performed much better. I used different kind of kraftpaper or gummed tape to finish the shell's, I was out of my regular kraft. I normally prefer using 80 g/m^2 kraft paper.

Zumber Posted January 10, 2017 Share Posted January 10, 2017 Can you share white willow formula please?? Link to comment Share on other sites More sharing options...
ExplosiveCoek Posted January 10, 2017 Author Share Posted January 10, 2017 @dynomike1, I've been thinking about them. Maybe it's doable in the bigger shell's, but for now I'll just leave them be. @Fckimdead, thanks! @Swapnilsutar, it's from Spanish PDF. But I exchanged the Ba(NO3)2 for KClO4.White/Silver Willow0.35 Potassium perchlorate0.15 Barium nitrate0.15 Aluminum, dark0.10 Aluminum, atomized, 100micron, 140-mesh0.10 to 0.15 (depending on theburn duration desired) Aluminum,70-mesh0.09 Red gum0.04 Dextrin0.01 Boric acid1.00 to 1.05 T I found that way it is easier to ignite, and also has high enough ignition temperature to get a good, white tail. The composition burns quite fast, this was the downside of exchanging the KClO4.I used 250# atomized, GD Al, and some aluminium rough powder from a metalsaw line of a friend of mine to make this comp. I don't remember how much of the coarse aluminium I used, was 5-6 years ago that I made these stars I believe. The other 6'' was the willow + FeTi + Ti from the Spanish PDF.

jerronimo Posted December 1, 2017 Share Posted December 1, 2017 Very, very nnice shell's!Those breaks were indeed huge, that silver/white glitter looked really nice, what formula did u use? Link to comment Share on other sites More sharing options...
ExplosiveCoek Posted December 5, 2017 Author Share Posted December 5, 2017 (edited) The white glitter to blue one's is the Fe2O3 based Spanish glitter. Very nice and slow glitter with good hang-time. There are also some golden streamers in there, they are BP + SrCO3 + Sb2S3 based. It's a composition from Mike Swisher I found once at Passfire.
