MilkyJoe Posted March 11, 2009 Posted March 11, 2009 That last mine was brilliant! well done. ~Milky~
Yankie Posted March 12, 2009 Posted March 12, 2009 IT RAINED!!!! OMFG!I let off everything I had lying around, hightlight was this 3" shell.Plastic shell, pasted with gummed tape, 1/2" TT rising comet and some pumped golden glitter stars in the lift, burst was cut D1 stars, plain BP burst, no flash. 3inchD1.wmv
pyrogeorge Posted March 12, 2009 Posted March 12, 2009 That last mine was brilliant! well done. ~Milky~ That starmine was intense, like a wave of fire thanks! And another one 3" ball shell
Steps Posted March 12, 2009 Posted March 12, 2009 thanks! And another one 3" ball shell Sweet dude, little more practice on burst and your set. Sweet shells Yankie, looking forward to more
al93535 Posted March 15, 2009 Posted March 15, 2009 Plastic shell tester, going to reduce the flash in the break.... 6inchtester.wmv
TheSidewinder Posted March 15, 2009 Posted March 15, 2009 Very nice shell! I saw "Tester". Single, or part of a series?
al93535 Posted March 15, 2009 Posted March 15, 2009 Ahhh, I would consider it a good shell, with different stars.. Lots of testing... Testing the methylene chloride seal, the new fuse, priming, x-matching, lift and burst... So I used some easy to make glitter. 36-6" plastics for the 4th party, 52-4", 12-8" and 6-12" shells. We will be testing the 8's and 12's next. I want it all right before it goes to an audience... Man i have to make a HELL of alot of break...
TheSidewinder Posted March 15, 2009 Posted March 15, 2009 Sounds like you have your work cut out for you, though it should be fun! Make sure to get video for us. We need Winter entertainment.
Richtee Posted March 15, 2009 Posted March 15, 2009 Lots of testing... Testing the methylene chloride seal, the new fuse, priming, x-matching, lift and burst... Soo..what's your opinions? You did no pasting on that one? What type of burst?
al93535 Posted March 15, 2009 Posted March 15, 2009 No pasting at all, Simply dissolving the seams with dichloromethylene and closing. I used KP burst, 6:1, using airfloat KClO4, airfloat charcoal (hardwood) commercial, rubber makers sulfur and dextrin. I used 15 grams of flash to break it with, which was obviously WAY too much. that was my report mix, KClO4 64, S 6, pyro al 30. My opinion was that it lifted well, but it broke too hard. The fusing, x-matching and timing were great. I will reduce the flash to 5 grams and test again.
Richtee Posted March 16, 2009 Posted March 16, 2009 A 3" shell... I call an "Octo-pow". Description posted with vid.... Octo-pow
swervedriver Posted March 16, 2009 Posted March 16, 2009 Nice shell Rich, those were timed well! Now I'm on a mission. Beat Richtee's timing or Bust! heh
Richtee Posted March 16, 2009 Posted March 16, 2009 Nice shell Rich, those were timed well! Now I'm on a mission. Beat Richtee's timing or Bust! heh In all honesty- it was mainly luck ;{) The 1" balls used BP primed visco fuses. I WILL admit to slightly different lengths, but given the method- I got lucky...
Yankie Posted March 16, 2009 Posted March 16, 2009 Nice shell Richtee, very similar to one I made, same method for the inserts, was beautifully timed, was like a crunch the timing was so good. unfourtunately I didn't get the shell entirely on film, only the audio and the las few seconds of the silver sparks burning out.I made a 3" blue smiley face shell today, hope it works, also made a ring and bow tie. Will be shooting them and many more on the 28th hopefully, having a show for a birthday party.
Yankie Posted March 20, 2009 Posted March 20, 2009 I am baffled and annoyed, I made a batch of C8 cut stars, and decided to add some 20-100 mesh MgAl for a nice effect. I used water and metho to wet it, it went well, then after about 2 days of drying it formed white crystals all over the surface of the stars, a day after that and the slab rose like a cake, I went to break them up but they were all crumbly and wafer-like.... WHAT HAPPENED!
andyboy Posted March 20, 2009 Posted March 20, 2009 The nitrate reacted with the MgAl. Did you force dry the stars?
psyco_1322 Posted March 20, 2009 Posted March 20, 2009 Next time you cut those stars spread them apart and get a fan blowing on them. No more than a fan, and by the end of the day a lot of the water that causing you issues will be dried up. If you want, leave the fan on for about 1-2 days. Then allow natural drying for about a week and they should be as good as gold. It may help to throw in a percent or two of boric acid. Some will say it won't help but not hurt in trying.
Yankie Posted March 20, 2009 Posted March 20, 2009 I had a suspicion that something reacted with the MgAl, I didn't know that MgAl reacts with nitrate, I only thought Al reacted. Well you learn something new every day. I decided to make them with acetone, plus it drys in 4 hours . How much red gum should be added? I used 5% but the stars broke easily, I have about 150g of useful stars left, out of my 500g composition.... The stars that I still have are very poor, all different sizes and odd shapes, I am not having much luck. I am going to get a star plate
psyco_1322 Posted March 22, 2009 Posted March 22, 2009 5% red gum should have been ok for holding them together. If you want you could bump up to like 7% and try that. I would just bind them with dextrin next time and eliminate any issues of them falling apart. Odd shaped stars are good for test shells. If you need to test something like your break or lift and need something to fill the shell, you can always use the not so good stars.
Miech Posted March 23, 2009 Posted March 23, 2009 I'd just go with plain water and dextrin. I always dry them at roomtemperature or slightly below, and I have never had any problems with soft stars or driven in stars. Yes, it does take more patience when you bind them with water, but they should be dry in two weeks.
Richtee Posted March 29, 2009 Posted March 29, 2009 3" shell: probably the best yet Nice shell, eh! What was the rising effect?
yellowcard Posted March 29, 2009 Posted March 29, 2009 (edited) I've purchased some 3'' and 4'' hemis from pyrodirect some time ago(nice price btw). But these hemi's have 2 fuse holes already punched in 1 half. Normally I just use simple visco wrapped in papertape/gomtape and glued in with woodglue as delay in my round shells. So these holes are way to big(9mm, I only need 4mm). Do you guys think that these holes are bad if i want a nice symmetrical break ? I thought of just drilling a third 4mm hole, glue the fuse in, and just fill the 9mm holes with woodglue and just paste regular. Thanks . Edited March 29, 2009 by yellowcard
