fredhappy Posted May 14, 2011 Share Posted May 14, 2011 This 4 "peanut turned out very nicely. I'm currently experimenting with KP. I am very pleased with the results. With 7/1 KP on hulls no booster is needed anymore for 4 inch double petal shells. The ring shell was broken with 50/50 KP on hulls and MCRH 5/1. I ve done this to compensate for the extra space for break, only using KP on hulls would have resulted in an over broken ring pattern. Unfortunately the ring was lying on its side, but is sure was there. The double petal was almost perfect . Great symmetry, nice inner petal symmetry and colour changes from red to blue were very pretty and instantly. I ve build a bunch of double petals using all kinds of construction methods. Spiking of the inner petal with flax wire, and building inside out. All these methods didn't really work for me. This shell gave me the best results , by simply using a 2 inch hemi to form a depression with rice paper and filling it with 6 mm shimizu B70 stars. I'll try and reproduce the double petal pattern, but I am very pleased to have achieved this result. KP gives excellent breaks, not too speedy, not too slow. It burns hotter then BP, thus giving an excellent ignition of stars. Just screen the ingredients together. I ve not milled my C and S. C was just grape. I love the fact that I do not have too boost with flash anymore, and go through the hassle to mix and weigh the stuff everytime. I have no problems with 70/30, but it is a big plus to only need KP on hulls when building. I use a 7/1 ratio on hulls, and I love the results so far.... 4 inch peanut ring and double petal KP break.AVI Link to comment Share on other sites More sharing options...

Your double petal shell is about as good as they get.Thanks for sharing,BJV Link to comment Share on other sites More sharing options...
Zmuro Posted May 15, 2011 Share Posted May 15, 2011 Very nice shells Fred. The double petal was great, what formula did you use for red and blue stars? Link to comment Share on other sites More sharing options...

FREAKYDUTCHMEN Posted May 15, 2011 Share Posted May 15, 2011 Best 4" double petal I have ever seen!I'm glad this way worked out well fred, this way is the one I prefer, no hemi's or other stuff inside your shell, only thin paper.Like I already told you, it's nicer to use a bigger inner petal, I think a 2.5" would be perfect. Looking forward to see a 6" double petal from you. Link to comment Share on other sites More sharing options...

fredhappy Posted May 15, 2011 Author Share Posted May 15, 2011 Thanks for your comments guys. Next time I'll build a Saturn shell this way, and I'll use an 2.5 inch hemi. Stars for outer petal were 8 mm buell red to 4 mm bright blue core ( 1.5% Mg/Al), slurry primed with KCLO4 hot prime, and then a final Si meal dusting.Everything lights reliably as far as I can tell. I am very precise with screening my stars. I screen with up to 1 mm precision, those screens cost me a bundle, but are worth every penny. The 4 mm bright blue cores were all nice and round, unfortunately they burned out rather quickly. The camera doesn't pick up the blue very good, but the change was there.I ve got loads of these 4 mm cores, but will simply roll them up to 6 mm, and use them as longer burning cores....the joys of star rolling.. Inner petal stars were 6 mm shimizu B70 with CuO. I like this blue, it gives a nice contrast. Al star compo's were just screened, nothing fancy, Link to comment Share on other sites More sharing options...
21littlewolf Posted July 22, 2011 Share Posted July 22, 2011 Very nice 4 inch shells. Your shells look very professional. The double petal was awesome! Link to comment Share on other sites More sharing options...
angelluis Posted August 4, 2011 Share Posted August 4, 2011 (edited) I myself have made a few 4 " D 1 shells they where very nice but where plastic with 5:1 bp on rice hulls and about 8 grams slow flash but seeing how beautiful your breaks are with just screened kp and paper hemis I am making the switch to biodigradable .
