Glitter and firedust are great. It may be a cold day in... (eh,hem) before I exhaust those options! 🙂

Hi it's great that there is a topic about cakes. I really like to play with them. It doesn't take up much space, it doesn't require a mountains of ingredients.I have created my own or modified from sources star compositions. in one way or another, they are similar to all the others, but they are adapted to a small shells. Differs in that the stars are not too bright and have a suitable delay and small diameter, which is suitable for small firework shells. Cake are my main fireworks, so I spend most  time on them. 

 

Before i begin i really loved rockets and shells, also im a big fan of candles and fountains but cakes its a chance to somehow create a more stunning display. Also you can play a lot with timming, rythm, show design and so on.  Making small shells that look good is a real challenge, this seems a great discipline.

Im glad you liked this thread, really apreciated.

I want to make sure i have this straight. In the first Pic, that's the layer of pulverone and dextrin which is pressed underneath the clay plug w fuse. It could be pulverone or star comp which ignites upon lift and who's purpose is to leave a trail to apogee lighting the visco to the bombette payload. Yes? Great stuff here! 

You can watch it by yourself at 8:48, they show the tooling with the fuses, they add clay, then the tail powder + some bp and then press the tubes. Look at the finished inserts at 9:19. 

Watching firework factories is a great chance to learn first hand how other`s pyro think and how they work, making the process more faster and effective is also a good improve to learn.

Can ask for you right now. There any comp. Can by compresed, glitter or   firedust, color to ,but for color is to expensive. For color beter add few drops color composition slury, anyway for color need hot prime slury  ontop of the color  and dip in bp grains to got ignition.

After the first increment of clay, the tooling is shaken in order to settle down the clay, after thisyou can add the moist color comp, shake again, add the priming + bp grains, tap it with the pressing plate to keep all tight and then press. A simillar process as what i mentioned is shown at 7:38 but in the video is used for adding delay composition + priming for small salutes.

ok i understand but my question is hoy are you fusing each tube? 

punch 2 holes per tube or just one? sometimes this affects each delay of each shot.

 

Tubes are drilled with 4mm holes to take 3mm diameter fuse. I use a simple chaining of one tube to the next and have never had problems with launch pressures. However, the fuses need to be secured with tape to stop them blowing out prematurely. Here's a three-tube "cake" post-firing

Nice set up, yes the tape does the job for protecting the sequence. Those tubes look good, are those rocket tubes?

I don't think so. They're just parallel wound tubes that come as 50cm long tubes which I cut to length. ID is 1/2 inch/12.7mm.
