Hello everyone, today I will show you how I made a 50mm (2 inch) firework shell.
I began by making the time fuse. For a shell this size I made a 2 seconds spolette wich consisted of a kraft paper tube ramed with black powder.
I then formed the casing around a 40mm PVC pipe with 4/5 turns of thick paper. This leaves enough space to make the spiking and the pasting and still have about 4mm of clearance with the mortar. This amount of clearance is very importante : You don’t want to make your shell explode in the mortar !!
I done the spiking in a terrible way but it works so… This step is very important beacause it enable the shell to build up pressure when it explode otherwise it will just tear apart and the stars will fall.
After the spiking comes the pasting wich main goal is to fireproof the shell and make the wall thicker.
The shell was filled of about 20 grammes of stars and packed with granulated black powder.
Once it was done I fused the shell with home made quickmatch and put the lift charge wich consist of a tenth of the weight of the shell so about 5/6 grammes of granulated black powder for a 50mm shell.
The quickmatch is just two string of blackmatch (black powder coated cotton string) in a paper tube.
At this point the shell is done, I just wrapped a piece of paper for the finish and I enjoyed the show !
DON’T TRY THIS IF YOUR NOT SURE OF WHAT YOU’RE DOING !!!
