AdmiralDonSnider Posted July 12, 2010 Posted July 12, 2010 As I´m into color changing shells now, I wonder how large one should roll the cores (final color). I know that every comp is a thing on it´s own, but it should be possible to give rough guidelines. To have a beautiful change a low light comp usually transites to a bright one; therefor streamers are usually layered over color and not vice versa. This would give the following popular core comp types: - chlorate color- perchlorate color, say here: metal fuelled such as Veline- strobes- Koro comps (fast flash core used by the Japs)etc. Can anyone experienced suggest some starting points for the core size, assuming coreless stars?E.g. would 4mm be too large for a Veline core? Sure, it depends on what you want the cores to do; I´m personally aiming at a click-on color by now, like the ones popularly used in charcoal, glitter or brocade shells. They are expected to give about 1-1,5 sec of a bright color finish. I love this effect. Another question that came to my mind is whether one should use a changing relay when switching from streamer to color in these stars? Thanks for your help!
AdmiralDonSnider Posted July 14, 2010 Author Posted July 14, 2010 No suggestions to share? Today I did some tests with my Veline green cores and I think that the size and uniformity of the cores is pretty important, at least with such slower burning perc stars. Shimizu says that the changing relay buffers some of the deviating burn speeds of uneven stars - I still wonder if this would be a good choice. I fear I´ll have to drill some sizing screens for the small guys.
