Holy shit! That went way the hell up there... The delay was Loooong, not to mention the time delay on the sound from the break and the dragons eggs. Wow... The pics of it look totally proffessional, you are definately a damned good pyrotechnition. =) wow....

Wow is right. Damn nice shell, Al.

 

How many paste wraps on that shell, if you don't mind revealing your secrets? ;)

Thanks guys. I was a bit disappointed about the pistils burning so fast. I wish they would have spread farther.

 

I had 4 layers of pasted 70lb paper, and 2 layers of 40 lb pasted paper. These were overlapped over the previous strip by one half. So really 8 layers and 4 layers.

 

I make the hemi's myself, and so I start with a rather round starting point. Also I make football shaped papers to paste. This really helps to keep the shell uniform and round.

 

Like this:

That goes exactly half way around the shell.

 

And just in case anyone is wondering, I make the hemi with 4 layers of 70 lb kraft.

doesn't the football shaped papers are too time consuming?

So what. Al takes his time and the results are obvious.

GREAT job Al ! Chemistry as art! You, sir are a master craftsman.

 

What's your estimation of the height at the break, and how much lift powder did you use? Also, while I'm being nosey, were those lead tetraoxide dragon eggs or bismuth subcarbonate?

Al, I have to say that it one fine looking shell! Being a member of WPA I have seen some very nice looking shells and rockets and I would have to say you would give some of the big boys of the club a run for their money!!! By any chance you a wpa member? If you are, do you plan on going to "Do-It"? I would love to pick your brain on some stuff.

The football shaped paper take about 20 minutes of extra time. But I would rather spend the time and have a nice shell, both in appearance and performance.

 

Humm, My estimation of the height: about 600 feet or so. I really cannot begin to estimate the diameter of the flower. I am sure with some math I could do it, but I'd rather not :)

 

I used 98 grams of lift, the shell weighed just under 1600 grams. My lift is home made, -6 +12 corned grains.

 

I am not a member of any pyro group yet, I am however joining WPA this January. I want to attend both WWB and Do-it!

 

And thanks for all the compliments!

Well Al, If you do make it to Winter Blast let me know! I would love to do lunch and pick the brain!! Me and a few friends have started out making shells about 1 year or so ago and would love to learn some good tips. Also WPA is always looking for guys to do "how to" classes for both Do-it and Winter Blast so if that might be your cup of tea let me know!

 

Thanks

George :ph34r:

Cool thanks for the info, those shells look better than 90% of the manufactured shells we have been shooting in shows lately. :lol:

Al, as always, that was a high-class device. Keep up the good work!

 

And noslo98 is right - better than some professionally manufactured stuff I've seen.

Here in Belgium you will be lucky if you can buy a 3" shell for 20 $ -_-

 

Hey Al, how did you put the pistil in? Did you just put the glitterstars inside you break charge?

 

I don't know how to make a pistil in my shell, can someone help me out?
