Not all homemade hehe the quickmatch between the mortars is comercial! 

I like to share with all of you my first mini aerial shell display, I hope you like it, it was fire in new year and Im very happy with the results.

Very very nice! Love the "flat" breaks on some of them. A little off topic but, I am curious on why you chose to make canister shells instead of ball shells? Is there advantages to canister shells?

Cylinder shells are awesome, ball shells are just your average everyday firework, so are canister shells.

What is the difference between a canister shell and a cylinder shell?

Cylinder shells are spiked and made entirely by hand from paper, chipboard and string. The burst strength is mostly dependant upon the materials and techniques used. Can shells are purchased, usually are bulk filled with stars and the burst strength is dialed in with boosters and flash. Their similarities mostly end with their shape.
I love cylinder shells because of the skill and dexterity required to execute them, it's rewarding and the burst patern is just a matter of preference.

I have more practice building can shells, when I started building shells Im was not having access to hemis then I start to learn how to build italo style shells, I dont have preference in one or other, is depend the effect you want, for example the ball shells are perfect for the simetry and can shells are nice to build multibreaks

I dot not like cylinder shells for two reasons:

 

1. It is impossible to obtain a symmetrical aperture;

2. The cylinder shape obliges to use a star plate instead a star roller.

 

For the second reason, using metals like titanium of a particular mesh will grip the pistons of the star plate inside its cylinders

and everything will finish into a big mess.

 

The biggest firework in the world was a rounded japanese 48" shell and not a 48" cylinder shell.

The multibreak will be obtained also with a traditional rounded shell playing a lot with the delays.

Not all true it will depends on the spiking pattern you decide to use, in spherical shells are easier to obtain regular pattern but that can be done also in cylindrical one. I like this video inthe end there's an explanation on spiking patterns and effects on breaks.

Is joined like mascletà, quick match with timefuse, 2s of time fuse

The multibreak will be obtained also with a traditional rounded shell playing a lot with the delays. 

 

It is not impossible to get a symmetrical break with a cylinder shell, it just depends on the orientation of the shell to the viewer which, unless the shell is mounted as a header on a rocket, is largely at random. 

 

It is also not required to use pumped stars in a cylinder shell. Single break shells can, and are, easily made using cut stars, or even rolled stars if you prefer. When building multibreaks pumped comets are generally necessary to provide structural integrity, but then it's something of a moot point because how many guys are building multi-break ball shells? I know people do build peanut shells, but cylinder shells are far more conducive to multi-break construction. Also, there are solutions to problem of pumping stars with hard metals: use a small layer of comp without metal or chipboard disks. Yes, it's more work, but it can be done. 

 

As for the biggest shell. 1. So what? 2. Comparing ball and cylinder shells based simply on diameter is somewhat misleading. The volume of a cylinder is 1/3 greater than a sphere of the same diameter. That aside, many Italian and Maltese multi-breaks are as long or longer than the guns they're fired from. I've personally made a 4" multibreak that was over 22" tall. A 4" ball shell is...4" tall. 

 

I like ball shells, and admire the skill it takes to get a perfectly round break, or a well time color change, but man do I love those big multi-break logs.

Really nice setup Aspirina ! Great shells.

Quick question: can you share some details about the TF to QM link? How did you do it?

I hope is clear enough!

It is too me, thanks! Basically just like fusing a shell. Was hoping for some quick trick in order to connect everything like they do with a pyroclock for instance.

But then the powder core is way bigger so it makes sense that you have to crossmatch it with TF.

No quick tricks hehe, only patience, cord and paper
