Alright guys, I spent quite a bit of time working on a 3'' cylinderical multibreak shell, and well.. I finished it. Im having a hard time deciding what to do next. I am pretty limited on chemicals but was wondering if you guys could just give me a few ideas of what to do... I dont want to make anything bigger than 1'' for rockets and 3'' for shells/mines. Thanks for reading guys..

If you have aluminum or Ti maybe try a farfalle shell. Though, it's quite hard to pull one off good in a small size such as 3", it would still be a project a bit more in-depth with thinking than just a standard canister shell.

Very Nice, but I dont know what those things were or how they were made... were they comets?

Might I suggest my favorite? Breaking glass comets or palm tree shells with rising palm trunk. Both are a bear to master, require lots of research and trial but are gorgeous when done right.

 

Parlon screen cut stars are rich in color, easy to make and don't take to many chems.

 

Z-bomb inserts are pretty cool too.

I'm sorry, but what the heck are breaking glass comets? I've looked and looked but can't find zilch on them.

 

You could try making some cakes if you have the time to actually try and perfect them. Or color changing stars.

Haha thanks for showing my video here.

This weekend a 4 inch farfalle will be launched. I really like to make those shells. I sure recomend building a farfalle shell.

From Eric Hunkins:

 

This formula\method was tested side by side with breaking glass comets from Ace and was judged to look better by those observing.

 

Meal D 40%

4F 26%

Charcoal 80 mesh 5%

Aluminum 12%

Sulfur 12%

Dextrin 5%

 

A specific aluminum is required.

 

I used commercial Meal D, but home-made will work if it is of a decent speed. The 4F was commercial but a granulated home made version would work also as long as it of a decent quality. This would be an ideal use for red gum granulated powder. You could also use the fines screened from 2F.

 

Testing was with 2.5” comets. I am not sure how smaller ones would work. Comets were hand rammed with a 3lb deadblow. Pressing them would probably be better, but I wouldn’t press them too hard and I would drop the water slightly.

 

All of the ingredients are mixed together except the 4F, whetted with 4 - 5% water. The mix is kneaded a couple of times over 15 – 20 minutes to allow the dextrin to set up. The 4F is mixed in at the last minute and then the comets are pressed. These will take 2 – 3 weeks to dry. If you try to force dry them, they may take considerably longer.

Or you could go into bombettes like I did. Superb effects with mousy devices, probably the most efficient way to use stars. As a side effect there would be one pyro more knowing about these, they´re really a blind spot of amateur pyro...

After doing some research I have decided to make a 3'' cylindrical crossette shell. Any tips or teqniques you use for making them?

Quite small for a crossette shell, usual sizes are 5" and more. You´ll have to use quite small stars, don´t know if it´s possible, but with the right tooling and technique, it might.

You can make 3" crossette shells without too much trouble. Seven 3/4" crossettes fit in a ring in a 3" shell. I've made them this size, and they're not too hard. I wouldn't go much smaller than that though.

Depending on how the shell breaks, the ring can be extremely pretty! I saw one recently on youboob that was pressed with one added increment to each crossette so they would break one at a time. I have no idea what the shell size was though.

How well do the crosettes below 3/4'' work?

Guys,

If he is limited on chemicals, he might be able to afford crossette tooling, and making it is a task in itself. Although a good ring shell made with crossettes is amazing, me a asilentbob made one at the 08 PGI convention.

 

If you have rockets up to an inch, try putting some nice shells on top of them. A 1lb (3/4") rocket should fly 4" ball shells or 3" one break canisters, with 3lb (1") rockets you could get more exotic and add another break or a bottom shot to your cans. Speaking of rockets, try staging some, 2 or 3 stages, a salute and a camera. See how high you can get them to go.

 

You could always try your hand at timed inserts.

 

Breaking glass will require the correct Al as dagabu stated. I made up a batch of cut breaking glass stars bound with resorcinol glue for some 4" canisters. Hope they come out nice, we'll see on Christmas.

Those suckers are a bear to dry!!

The ones I have made only jetted out the fuse hole, PITA. I have seen a bunch for sale at PGI and the like that look great in the air so someone knows hoe to make them well. Gary Hansen at Precocious Pyrotechnics sells them.
