3'' shell. question

[lokys]

hy, for all..

 

 

 

I want to ask how i can increase my shell break? 

 

This is my shell video : http://www.youtube.com/watch?v=LZVb3gRI4IE 

 

burst, bp on on hulls, booster - 2,1 g thunder flash #2 , stars Red on D1 glitter .. Red stars not ignited, but it's no matters.

 

pasted 3 strip method ,5 wraps Kraft 70g paper.   hemispheres - 3 snowflake 120g paper. 

 

if i put 3g booster ? or increase number of wraps ?

 

or I can do something else ??

 

 

 

yes, yes, my english is not wery god, but i think yuo-all will understand me

Why break the shell harder? It sounds like you are blowing them blind already. I use 10 grams homemade 2FA with 1:10 whistle coating them. They break fine for me.

I think it's to small for 3'' shell.. diameter of this shell was abuot 10-15 meters, I have seen biggest, and I want largest break in the sky..

What kind of hemi's do you use???

 

Just do one step at the time, or increase the amount of layers (for normal chinese hemi's 5 should be enough) or ad more flash.

 

btw the link doesn't work.

[dagabu]

or ad more flash.

 

Really? Flash? I would think the brisiance would shatter the stars.

[lokys]

My hemi's is home made, one hemis made of 3 layers of paper ..

hmm, i`ll try to ad more booster..

3'' shell D1 glitter to red , fail

[Mumbles]

Your stars are burning out before they can reach their full spread. Try a slower mix to see how big of breaks you're actually getting. I imagine it had something to do with the red stars not lighting. That's just a priming issue.

 

I'd go with more pasting personally if you arn't satisfied. Solidly filling the shell, and piping fire to the center did quite a bit to improve my breaks too.

 

I think people watch too many chinese shells, and get obsessed with bigger breaks personally. Sparse, but huge, breaks isn't an advantage.

[lokys]

stars in this shell were : Red ( K. Chlor ) -> sulfures prime -> D1 Glitter -> prime BP , i don`t know why red stars is not ignited, in another piro stuuf they work well..

 

thanks, I `ll try with another,slower, stars composition ..

 

maybe i`m to many watched another people shell`s.. but i want , that my brake wuold be better, it is not sin.

I think the shell and the rising effect looked great! I didn't see much red but that is as star issue, not prime. D1 is plenty hot to start the star.

 

I wouldn't change a thing but look at the red comp.

 

Bravo!

With a thin casing the brisance is not that much of course. And there's also a difference between flash and flash. It's one way or the other, you can have good breaks on 8"" with only 4 layers of pasting, so....

Depends on the type shell you build. I haven't seen sparse chinese shells, or it should be that type of effect.

I can show you enough shells breaking hard and still have a perfect dence and symetrical break, but most important big.

Getting more out of a certain amount of powder is true art.

 

Lokys, After seeing the vid, I don't think your burst is too soft, think you'll have to work on your stars first.

Try long ballmilled TT to practice, they light quite easy with a thin layer of fast meal. This streamer effect is easy to make and is easy for studying the video's you've made.

I know that the Pyrotechnics is art, and it is not easy way, but this way is very interesting.

my D1 glitter is ballmiled abuot 40 min, i`ll wuold try 25min or 30min,in onother piro stuff these stars look`s greate..

yuo are right to say ,that to practice need streamers, they are cheapest then colored comositions ant anothers.

 

thanks, for answers..

Looks like a good break for glitter but little red is shown. Try to soften the burst charge till all the stars show rather than get shattered. If you go for really big breaks they will have to be sparse as there will not be enough stars in a 3" casing

 

A 3" shell takes typically 110 stars of 6mm, and 8 inch shell takes about 150 stars of 1" diameter. There are more stars and they are bigger so they burn for longer and you get bigger burst spheres. You cannot get good breaks from a 3" shell that compare with a good large shell.

[FREAKYDUTCHMEN]

6mm stars for a 3" is too small, and 25mm stars for a 8" is too big

[lokys]

6mm stars for a 3" is too small, and 25mm stars for a 8" is too big

 

 

 

I agree with you , i think in 3'' shells: 10mm-12mm stars are great.

[Mumbles]

For colored stars 6mm isn't a bad size in 3" shells. 10-12mm is approaching the larger side of things for streamers. I guess it depends a lot on burn rate. It's the size I generally use for the inner petal for 6" DP shells. I've gone as far as using 6mm stars as the inner petal in an 8" I made, which was 5". Those stars burned exceedingly slow though, around 3.5 seconds.

 

Another thing to keep in mind is that the smaller the stars, the more burst you can fit in there, and the bigger the break gets.

[lokys]

i don't say what i use 10-12 mm colored stars, i used 5mm Colored core to streamers or glliters and anothers compositions.
