Foguete Posted October 8 Posted October 8 Hello to everyone, welcome to this thread. The main focuss is to share diferent building tips and techniques involved in cake manufacture from stars, building inserts,insert tooling, tube sealing, fusing the cake and more! Do anyone has any experience with It? Please feel free to share your thoughts🎆🎆🎆
cmjlab Posted October 8 Posted October 8 I believe there are a few threads here on APC related to making cakes and a few more titled "bombettes" (those having more to do with manafacture of the inserts for cakes and less to do with cake construction or tubes). I've tried them a few times with some success, but because of how much time they seem to consume and the difficulty of working with such small effects, I just sort of lost interest in making them anymore. I look forward to your attempts, and hope you record them to share here. Maybe I'll learn something from you that will reignite my interest in making them! Good luck! Chuck

Thank you for your comments, i 've been doing this for a while and i can agree that is a time consuming work , however with the propper tools you can speed up the process for good. Here is a test that i did some years ago: I used 7 mm silver glittering stars (modified D1 glitter) , 1.2g of flash for burst (KClO4+ Ba(NO3)2 + Al + S. This was a 16 shot fan quick cake module, this is meant for compound cakes. received_181772546935006(0).mp4 1

Can you elaborate on the burst charge composition - ratio, and does it have a unique advantage compared to regular KNO3/Al/S slow flash or 7/3 hot flash for this application?

Can you elaborate on the burst charge composition - ratio, and does it have a unique advantage compared to regular KNO3/Al/S slow flash or 7/3 hot flash for this application? Thank you very much. The flash composition is: KCLO4 30% Ba(NO3)2 20% Al 30% Sulphur 20% I used this because the lack of perchlorate avaiability. I have never used nitrate based flash so i cannot tell if its suitable or not, 70/30 flash is great for reports but too energetic for colour breaks. To be honest when It comes to reports i stick with shimizu thunder #3, always great results with it. In cakes you must achieve a Hot burning composition that light all the stars but strong enough to disperse the effects correctly. I also used this composition with good results KClO4 50% Al 40% Sulphur 10% Slower flash but It shatter the bombette easy. I Will post another video with this composition so you can tell the diference.
Foguete Posted October 9 Author Posted October 9 This is a 19 shot cake, btw all the cakes are 1.2" caliber. The burst is KCLO4/Ba Nitrate flash. Some tiger tail stars (vineyard charcoal) and silver glitter is used (replace Na bicarbonate with barium carbonate). received_2740148086197763(0).mp4
johnnypyro Posted October 10 Posted October 10 Nice pacing of the shots. Any photos of the device and fusing? This bit I’m still working on.

No photos unfortunely, all rows are connected with QM so the order goes like this: Row1- fast visco - Row2 - common visco - Row3 - fast visco - Row4.

You do realize that, Quick Match ( a piped black match item ) and Visco. ( a lacquered spun type fuse ) Are two distinctly different products.

Each row is composed of 4 tubes (fan shape) each tube in the row is fused with QM. These rows are interconected by 2 kinds of visco fuse,each one with diferent burning speed. That is how i got his firing pace

LiamPyro Posted October 23 Posted October 23 Here’s my attempt at a cake insert, pardon the terrible out-of-focus video: IMG_0263.mov I used a 3/4” ID x 2-1/8” tube and pressed clay plug with time delay fuse imbedded (I used willow effect fuse so that it also created a tail). Buell red and C8 +15% FeTi stars, granulated BP + 7/3 flash break. This was mostly a test to see if the stars would light, which it appears most (if not all) did. 1 1
Darkonez Posted October 23 Posted October 23 This is perfect timing! I’ve just made 2 12 shot cakes. Just need fusing and filling!
johnnypyro Posted October 24 Posted October 24 (edited) I have three types of visco for cake fusing - 1 cm/s (standard), 10cm/s, and 100 cm/s. It's not very convenient for say half second delays. I really could do with 4 or 5 cm/s "pink" visco, but I can't find it in the UK. Edited October 24 by johnnypyro typo

Chuck When you say "bombettes" do you mean the actual shells that go into the tubes? Thanks.
cmjlab Posted October 27 Posted October 27 Yep - bombettes being one name I've seen them posted under. Cake inserts, mini shells, etc.

Cake inserts, mini shells, etc. Yes, this is a bombette in the process, fuse Is pressed along with clay and a layer of moist pulverone + dextrin. All in one single operation, brazilian firework factories work this way, you can also use color or glitter composición in order to give the bombette a Tail. Once the layer Is dry the bombette Is ready to be loaded with effects, flash and finally be sealed. There is no need to prime anything. This differs of the chinese method however Is very effective, I've tested a Lot without any issue. Edited Sunday at 11:04 PM by Foguete
skysparkler Posted Monday at 05:51 AM Posted Monday at 05:51 AM 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. 1

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!

skysparkler Posted Monday at 03:06 PM Posted Monday at 03:06 PM (edited) 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. Edited Monday at 08:09 PM by skysparkler
