fredhappy Posted July 15, 2011 Posted July 15, 2011 (edited) I've shot this shell as a finale shell at a show at large party. There was lots of open space, and crowd control present. Outer flower were 10 mm bright blue to 6 mm buell red stars.Inner petal was c8 with Ti to b70 , which unfortunately appeared too dim. The inner pistil stars consisted of a beautiful silver wave compo with 70 mesh mg/al instead of the specified 300 mesh. That one is a keeper for me. Rising flowers were a 2" buell red, to 2.5 " b70 to 2.5 "c8+5% Fe-Ti. The rising flowers were attached with hemp rope, and worked flawlessly. Only thing that needs some more tweaking is the timing of the rising flowers, those could have been a bit faster. Everything was broken with KP on hulls 7/1, rising flowers included. I ve included a screenshot which is quite big. I should have converted it first, hope it works..... 6 inch double petal rising flowers WMV.wmv picture 6 inch.bmp Edited July 15, 2011 by fredhappy
vh718 Posted July 15, 2011 Posted July 15, 2011 wow that shell was perfect. i really loved the rising shells on the assent. i dont think it could have gotten better then that .
Mumbles Posted July 15, 2011 Posted July 15, 2011 I thought the inner petal showed up fine if you were looking for it. The issue I saw was that the inner petal transitions to blue while the outer petal is still blue so it kind of blends in.

C8 burned off too quickly, b70 cores were a bit too small. I was aiming for a double transition : outer flower blue to red, and inner gold to blue, where the gold to blue transition was suppose to give a clear contrast with the red outer flower. It's so much fun to build and design these shells, but obvious it is hard to get the colour changing timings right when working with multiple changes ... I'll keep trying though....

Karlos Posted July 17, 2011 Posted July 17, 2011 Fred: Absolutely perfect simultaneous switch off of stars! I did not see amateur shell with these quality.
50AE Posted July 20, 2011 Posted July 20, 2011 Certanly great effort and diligence, I love it when someone does its work thouroughly! You make one the best shells here mate! I can imagine your star screens are by 0.3-0.5mm difference. I
fredhappy Posted July 20, 2011 Author Posted July 20, 2011 Certanly great effort and diligence, I love it when someone does its work thouroughly! You make one the best shells here mate! I can imagine your star screens are by 0.3-0.5mm difference. I Thx AE and Carlos! My screens are all 1 mm accurate. The thing I do is I screen my stars multiple times. Try screening a batch a couple of times, you'll be surprised how many stars pass which are not the same size. Screening your batches a couple of times really improves the timing. Downside is you have some more rubbish stars then usual. The 6 mm red cores I used in this shell were screened multiple times, and were very uniform in size. Also, when I'm rolling and the stars are almost their targeted size, I keep them apart, and when they're almost done I add little increments to roll them up more or less exactly to rounded millimeters. It sure is a lot of work, but you get excellent timed stars this way.
