During a 2 month period  March to May this year I built 80+ cylinder shells from scratch using traditional construction techniques for a rocket festival display near to  my workshop in Sakgeow Thailand where i run my Pyro Holiday School.

I made videos of almost all the work I did stage by stage for anyone interested in making cylinder shells.

 

2 videos showing the finished shells and the show itself. These were all cylinders. I don't make ball shells :)

For anyone  interested in seeing how these shells were made here are a few clips showing some of the construction.

http://youtu.be/jQNVwLo_dag        Cutting end discs with an Allpax gasket cutter

These are just a few of the 50 or so clips on my youtube chanel showing different aspects of the construction.

I frequent your videos all the time, they are extremely well done. Love your work.
If only I had the money to come over and build some shells with you!
Thanks for sharing,
Jess

Great vids, Bangkokpyro.  Perhaps they would be a good start for an APC tutorial section?

 

Mumbles?

Paul,

I have watched your you tube on this big project. It is a distraction in life alone to get pyro done by a dead line. But to include the making and publishing of the work and still get the day job done and what ever else pops up is truly amazing. Kudos to you! 

 

Mark

How have I missed your channel?! This is fantastic content!  May I ask where you got your ball mill?

I've watched a lot of these as time passed, and i've spent some time on his webpage as well. He's got a few things going on that i don't care for, mostly along the lines of being a lot more aggressive then i'd like with tapping, banging, and shoveling stuff.

Just a matter of personal preference, i guess, but for example, i wouldn't use my hand shovel and push it in to the composition, scraping against the working surface when screening, or collecting the mixed product. It seams to work for him, but it makes me screech through my teeth.

 

Perhaps a bit lax on the protective gear as well, but i can see heavy fire-retardant equipment, and such as being an issue in the climate he works in. I got 30c here now, it's the peak of summer, and i can hardly breath just sitting down.

Anyway, i'm hardly going to go around saying "he's unsafe" since quite clearly he's got quite a bit more experience then i do, and the level of detail in his tutorials is quite nice. But i'd hate for him to get hurt, and never finish up the website... Yeah, how about that reason of concern for a fellow humans well being. I'm kidding of course. I don't want anyone to get hurt. Least of all me, but everyone else as close seconds. Stay safe, take care.

B!

Your videos are very awesome! I'm just starting out in the world of pyro so I'm trying to learn as much as I can before starting, and your videos are very clear. I also think Thailand is gorgeous so I'm jealous of that.

 

Thanks for the uploads!

I'm glad so many of you enjoyed the videos and found them useful.

I should point out in that the seemingly harsh tamping with dowels you see being done while the shell cases
were being filled was done while using Charcoal based stars which are pretty insensitive to impact and friction.
Should you be using Chlorate stars, stars containing any sparking metals, stars containing Antimony Trisulphide or any star comp of a sensitive nature tamping the stars with a dowel or rapping the case hard on the bench to compact and consolidate the content is very dangerous and likely to cause a serious accident.

When making large shells esp multibreak shells it is essential to ensure the contents of each break are packed solidly with no air spaces so the result is a rigid solid cylinder that will not compress and rupture when the shell is fired from the gun.
Consolidation of Chlorate stars should only be done by patting the outside of the casing gently along with pushing down using light finger pressure to settle the stars into the most compact configuration. The use of polverone filler in most cases particularly when using large cut stars case will help ensure a solidly filled case.
When fitting large comets inside the shell case rather than trying to force the final comet into the ring
and risk an accidental ignition caused by friction I prefer to aim for a loose fit that I can tighten up using wooden spacers as practiced bt Maltese shell builders.

If you use the chimming method, do you use wet cases, chim everything and let the casing shrink to really lock everything in place, or do you dry cases and chim a little harder?

It's shim not 'chim' and no I use dry cases. Only the final wooden spacer needs force to push it into position and tighten up the ring sufficiently so that you can turn the casing upside down and shake it without the comets falling out. I use mostly Balsa wood for my spacers; it's soft, bites into the comet sides and grips well.

Thanks for posting those. I didn't expect to learn as much as I did from the pasting video.

Man, you look like you have a whole firework factory to yourself! Definitely something I'm looking into for when I'm retired.

There are very few problems that cant be solved with explosives.
