patsroom Posted August 8, 2010 Posted August 8, 2010 Very Nice. Really enjoyed the Vidieo..........Thank You for sharing .............Pat
Ventsi Posted August 8, 2010 Posted August 8, 2010 That was quite amazing! You are really perfecting these! If you don't mind, can I ask how much flash you used in each and how you fused them?
Cookieman Posted August 9, 2010 Posted August 9, 2010 I really enjoyed watching that, great job "Cake Boss"
jimbo Posted August 9, 2010 Posted August 9, 2010 that was excellent,you must put a lot of work in to making those cakes.very repetative, are they plastic shells I would hate to paste that many shells maybe over a year or something or with some help 10/10
Coil Posted August 9, 2010 Author Posted August 9, 2010 Ventsi: I use 2g of KNO3 50 S 30 Al(dark) 20 flash in each bombete. Fusing is simple: I just ram visco into kitty litter. This is how my bombete look like: http://www.piro.projektas.in/forum/uploads/2_bombete.jpgSorry for my bad english. Coil.
portfire Posted August 10, 2010 Posted August 10, 2010 Fantastic work!!! How do you fuse each shot-tube? 1
davis050594 Posted August 10, 2010 Posted August 10, 2010 WOW!! That's awsome. Just curious, why do you use a wood plug on top??? Also, how many hours does it take to make something like that? I'm sure you get to a point where you just have basically a manufacturing line lol.
AdmiralDonSnider Posted August 12, 2010 Posted August 12, 2010 I wasn´t able to watch the vid, but here are a few questions: - is it right that you´re using low-quality paper, as found in consumer cakes, to roll the units? I found that they´re never made from kraft...- what´s their wall thickness?- did you ever use a thinner wall and did you see an improvement in the breaks when swichting to thicker walls?- why are you using nitrate flash, it´s rather uncommon?- the wooden top plugs are nice. I found it hard to sufficiently plug the top. The clay bottom plug is something that spoils the case balance in these bombettes, but it´s necessary for the delay.- what kind (rolled etc.) and size of stars are you usually using for both tailed and color stars? What are they based on, chlorate or perc? Hope you reveal a few details! I´d appreciate a future personal talk by the way, I´ve also been into bombettes for quite a while.
Ralph Posted August 15, 2010 Posted August 15, 2010 that was excellent,you must put a lot of work in to making those cakes.very repetative, are they plastic shells I would hate to paste that many shells maybe over a year or something or with some help 10/10they were paper tubes (take a look at the pics) I wasn´t able to watch the vid, but here are a few questions:- why are you using nitrate flash, it´s rather uncommon? nitrate flash is fairly common among armatures for breaking cake inserts I have seen it done a few times and do it my self for my 2" sky puke shells and they break well enough
Coil Posted August 18, 2010 Author Posted August 18, 2010 (edited) Hello all, sorry for slow response. I will try to answer to your questions. Portfire: To fuse this cake i use Visco, Fast Visco and Quick match AdmiralDonSnider: -Yes, I am using low-quality paper. -About 2 mm-No, I always use tubes with 2 mm wall thickness.-I use nitrate flash, because it is powerful enough to me. And in my country perchlorate is not very cheap.-I use only tailed stars because like i sayed perchlorate is not very cheap for me. Now i am trying to use chlorate stars but i am just starting In my cakes i usually use rolled TT (5-6mm) and pumped Win23 (6mm) stars. Sorry for my bad English. Coil. Edited August 18, 2010 by Coil
jimbo Posted August 19, 2010 Posted August 19, 2010 (edited) yeah, didn't realise they were the bombettes bunched up at first, sorry thought they were something else. Edited August 19, 2010 by jimbo
dagabu Posted September 1, 2010 Posted September 1, 2010 BAD ASS, VERY WELL DONE Again, Shhhhhhhhhhh! Stop yelling, we can hear you fine.
angelluis Posted October 1, 2010 Posted October 1, 2010 A Few Fotos: http://www.piro.projektas.in/forum/uploads/2_saliutai.jpghttp://www.piro.projektas.in/forum/uploads/2_bombetes.jpghttp://www.piro.projektas.in/forum/uploads/2_cake.jpgAnd video: What type of lift did you use for the bombetts ?
AdmiralDonSnider Posted October 1, 2010 Posted October 1, 2010 I´m pretty sure he used 3/4FA or a pulverone equivalent. The only thing that I don´t like about this kind of bombette design is the wooden plug. On the other hand it´s hard to find a good top plug. Many commercial units do use a clay bulkhead pressed in place, others use multiple disks or cardboard end plugs. I tend to think that the clay bulkhead is something that spoils the case balance, as mentioned above. If the top plug is flimsy, the bombettes tend to make a spray or bow-tie type break, nothing symmetric.
Col Posted October 1, 2010 Posted October 1, 2010 Coil mentioned the lift as being 3-4g of black alder. I`m making similar sized bombettes (28mm id x 80mm long), if they turn out half as good as Coils i`ll be happy
AdmiralDonSnider Posted October 1, 2010 Posted October 1, 2010 Coil mentioned the lift as being 3-4g of black alder. I`m making similar sized bombettes (28mm id x 80mm long), if they turn out half as good as Coils i`ll be happy Use a pusher disk (loaded after the lift and before the unit). This drastically reduces the amount of lift needed. 3-4g is plenty for units which I´d say come out at about 30-40 grams each.

AdmiralDonSnider Posted October 1, 2010 Posted October 1, 2010 A simple single disk or a piston? That sounds easy Just a cardboard/strawboard disk showing a small central hole and matching the tube ID in size. 1g will send the things 25 meters up.
Col Posted October 1, 2010 Posted October 1, 2010 Is it common for bombettes to have fairly thick bottom bulkheads? I presume the thickness sets the delay timing (encasing the visco) and provides protection during the lift.
