swervedriver Posted December 25, 2008 Posted December 25, 2008 (edited) Ok, this is my best yet, my fifth shell, my forth one blew completely blind. So much for the "veline style prime" on veline blue I guess, I'll have to get some dichromate for the super prime. And my BP dustover didn't light for some reason. Anyhow, here's my big 3 incher. I was standing a bit to close, still learning. It was still going up at 4 seconds flight time when it burst. I don't know what a big break is, but it filled the sky above me. hope you like it- 150 gram plastic shell100 lb tensile strapping tapeBP on grass seed burst1.5g 7/3 flash boost20g pulverone lift 3" D1 Glitter Edited December 25, 2008 by swervedriver
Mumbles Posted December 25, 2008 Posted December 25, 2008 Very nice. Something that is rarely mentioned, but those hotter primes usually need a layer of green meal over the top. Think of it as priming the prime.
swervedriver Posted December 25, 2008 Author Posted December 25, 2008 (edited) Thanks Mumbles. I put a layer of meal slurry over the hot prime, maybe one mm thick. After more afterthought, the BP prime didn't take fire I guess. Not sure why, the hot prime never had a chance. ps- they shoot fine out of a star gun test Not sure why my D1 looks so different from others i've seen, maybe it's my Al at 400 mesh. others I've seen have a longer hangtime Edited December 25, 2008 by swervedriver
Mumbles Posted December 25, 2008 Posted December 25, 2008 It could be the charcoal you're using. Using a good form(in terms of lift), will yield a faster burning star and shorter hangtime. I use commercial airfloat for all my stars. It offers decent hangtime. Certain varieties, such as pine, honey locust, etc are supposed to give excellent hangtimes as well.
swervedriver Posted December 25, 2008 Author Posted December 25, 2008 aaaaaah, that makes sense. good info Mumbles. on the video above, I listened to it with headphones on with the volume up and I can hear two brief whistle chirps from the comet as it is going up. It's a 1.25" veline system blue comp comet. i was thinking it was just some screwy audio thing that happened with my camera, but after few replays, i see a spark at the exact time of the chirps at 0:05. interesting.
jerronimo Posted December 26, 2008 Posted December 26, 2008 Personally I never use fancy primes to prime my stars, a good layer of green mix75/10/15 + 15 MgAl or Al seems to work just fine on round stars.
