Almostparadise Posted August 7 Posted August 7 I'm wondering about one of the images that are shown at the top of the main page when you log on to APC. It was only a quick look and I neglected to get a name. The guy was holding a giant ball shell over 12 inches and it looked like it had all kinds of goodies dangling off the sides. Are these garnitures that are side fused onto the ball shell? If so how does that work? I'm just curious what all was going on there.
Richtee Posted August 7 Posted August 7 Hmm... sometimes “tails” are attached to shells to keep them in a certain orientation in flight for the burst. They are loaded with a “top” and “bottom” Maybe that’s what was going on?

It is fast burning mixture formed as a pumped star and it is wrapped with few turns of Kraft to avoid all of its surface to ignite at same time. It is allowed to ignite from one side and it is primed with bp slurry and granules and it lots by hot gas /flames by lift charge.
Almostparadise Posted August 8 Author Posted August 8 Not the rising tail. I wish I could do better describing it. They look like fat rolls of quarters I couldn't tell what they were strong to the Shell with. I will see if I can find the picture.

It is called "Kyoku" If yes it adds another beauty to shell. It consists of Kraft paper tube of desired diameter and it usually contains pressed comets or simply stars at its both sides and bp grains in middle. At both ends paper disc are pressed just like we prepare mines. Hole is punched to middle of tube and time fuse is added to ignite burst. Look at position of tubes. If two tubes are placed horizontal then above two tubes are placed at right angle to bottom tubes. All tubes are highly secured with jute and covered with mask tape to prevent jute from being ignited by lift....All sets of tubes are timed differently with few second delay.

Almostparadise Posted August 8 Author Posted August 8 Ha! That was amazing!! I have no doubt that the shell in the picture I saw was set up for this type of an effect. The cylinder casings attached to the shell i saw looked about the same as these, except they appeared to be hanging around it. Top fused maybe off of one of the rising tales mounted to the top of the shell. Very nice!
Almostparadise Posted August 9 Author Posted August 9 (edited) When it pops back up I'll post it here. This is off topic but I saw a video of a willow shell you posted and thought it was beautiful. Now I can't find it again. It was a very delicate effect. Like small stars, but alot of them. Really amazing. I was wondering how exactly you did it. The stars etc. I also like the look of the full and bushy tail of well milled TT. Looks like a spider star. If there were a way to slow it down some so the stars could be smaller to fit more in the shell. It could help to get nice dense break like your willow shell. It would need a more gentle break so the stars would go into a downward curve. They wouldn't spread as far in that case which may be okay. Maybe some coarse charcoal or metal for a lingering tail?

If you try to slow down TT stars with addition of Charcoal then it will spoil bushy tail. if you want star to go downward curve you may use willow type formulation. There are two terms for this, Chrysanthemum stars and kamuro stars.....Chrysanthemum is fast burning star that dont form downward curve when shell is bursted and chrysanthemum is always bursted hard which means it uses much amount of burst charge, kamuro is slow burning star which use high charcoal than chrysanthemum & forms downward curve which is known as brocade effect.
Almostparadise Posted August 10 Author Posted August 10 Okay I understand. I have more questions about Tiger Tail Stars I will make a post in the newbie section.
Edwin Posted August 11 Posted August 11 found a clip of a fireworker in the process of making the kyokudu effect, in this case, its the splitting comets. 1
ThrownBiscuit Posted August 11 Posted August 11 I'm definitely going to try and do a shell with the kyokudu effect. I didn't know it existed before this thread, but it seems really neat.

Be sure that you time it precisely, another important thing is that it must be secure enough and survive against shock produced by lift plus jute or whatever you are using to tie it must not burn from fire generated in mortar while launching shell.
Almostparadise Posted August 12 Author Posted August 12 (edited) Haha! We must have posted 1 minute apart. Yes, that's the one. That is a serious looking shell! Edited August 12 by Almostparadise
Zumber Posted August 12 Posted August 12 And it is "Kyoku" No doubt about it. It functions like splitting comet. 1
