Great job on another video. It was great how you took the time to explain all the facts and myths about mortar tubes. I wish I would have seen your videos years ago as I began to learn and purchasing hdpe tubes, firing systems, etc. Great for those just getting into this hobby.
This is actually exactly what I was looking for. I thought you were going to cover the brands of shells so I clicked out of curiosity about what you were going to say about them. I was totally looking for this vid though. Thank you very much for putting this video together!
@@JoelRobinsonPyrotechnics I get about 2 tubes every year with 6 shells each then add them to my rack and now I'm up to about 5 tubes soon to be 7 I built what you call a poor man's rack last year but some stuff got put on it broke 1 of the tubes base so I followed your video on making a rack but made some slight modifications
Just to be safe, I wouldn't use those cardboard mortars if they got soaked. Being wet will cause the cardboard layers to unwrap. I would go buy a smaller canister shell kit that comes with an HDPE mortar. A good one to get would be the Sir Lancelot (Excaliburs just come in a kit of 6 shells). Than you can use that HDPE mortar to shoot your remaining shells plus any more you buy in the future.
Cardboard also expands, both near term and long term. Until now I have just been using the same dozen Excalibur tubes for everything the past few years.
the majority of my mortars are dr9. everyone says cannisters don't fit in dr9, that's because they haven't tried. I haven't come across a 60g can yet that doesn't fit. The only thing that doesn't fit my dr9 is hot shot braggin dragon ball shells and also critical acclaims. Those hot shot braggin dragon shells are huge compared to other ball shells. So when people say dr11 is for cannisters and dr9 is for balls. That's a bunch of BS. Cannisters soming out of a dr9 are going to have a louder thump, go tad higher, and are probably safer due to the increased thickness of the mortar.
I agree. Started out with a 12 shot dr11 rack because of all the bs around saying you have to use them but you don’t. I tried some dr9 and found they fit everything too! Won’t go back to dr11. All the cans and ball shells fit nice and snug in my dr9s and drop in nice and smooth too. Agreed with the louder, bigger thud out of the tube too.
Basic physics. A longer tube for a given shell will propel the shell farther on a given lift charge, so long as the pressurized lift gasses exceed the volume of the shorter tube. The lift gasses build over time behind the shell accelerating it up the tube. The serious "thump" when firing a shell denotes the gasses escaping the constriction of the tube after the shell exits, demonstrating that you still have compression. Ideally, the shell should leave the tube after the gas pressure has already peaked for maximum velocity. The faster the shell is moving when it leaves the tube, the higher it will go.
Yes, with diminishing returns and up to a point. There can be friction against the walls. Also when the shell is accelerating up the mortar, the air in the mortar is confined and will compress, counteracting the lift gases, which will be escaping past the shell. Probably not worth making the mortar much longer, but you can have fun experimenting.
If you REALLY want to you can harden up cardboard mortars and reuse them for quite some time. Coat them in side and out with Minwax Wood Hardener. Another method, you can also rinse them with a calcium chloride solution and then when still a little damp coat them with "water glass", sodium silicate. I did it to a batch of cardboard mortars years ago just for a project one rainy day. They still are in fine shape. Or just keep your HDPE or fiberglass kit tubes and forget the hassle!
I have some Premium Artillery Ball Shells that are pretty much the same size as average Festival balls. I wanted to get some DR9s because everyone says they are great for Festival balls. Though now I'm able to get Some Excalibur shells too so would it be safe to use DR9s for Excalibur shells? I saw a few guys put Excaliburs in DR9s and it worked but was it just a lucky shot or is it actually gonna work? I like to do some smaller stuff and some bigger stuff just for backyard shows on occasion. So should I get a mix of DR11s and DR9s or is it cool to just by a bunch of DR9s and save money by buying them in mass? Saving money would be great but i also dont want to get somthing thats not gonna work rite and be versatile.
At this time of this video, I was only aware of the 1.25" internal diameter DR9 tubes. Now they have 12" tall 1.81" ID DR11 tubes which would likely fit most ball shells and a lot of canisters since DR11 is 1.91" ID. I suggest getting a few of whichever you are thinking to test with your commonly bought shells before going all in.
I use different color electrical tape on the tops of my tubes, write it on a piece of paper to keep up with what shells are in each tube. Super cheap and easy way to keep up with where everything is. Just a tip
So I have been looking around and havent seen what I was looking for tell seen this video and remember where I saw red white and blue mortars. I have looked around and am struggling to find red white and blue mortars. I really want to build a few 30 shot patriotic racks for my 4th display. Any help would be so appreciated. That is for the informative videos Joel. Cheers youall!
Last July I had some pretty awesome artillery shells but after we had more. Since some of our cakes were still smoldering we wet them but someone drenched the cardboard mortars in water. I don't use them since I believe they'll blow up. What can I do? Are they ok? Should I wrap the tube is layers of duct tape? I want to be able to use these shells in the tube again. Anything I can do?
I had a neighbor light off fans cakes, those smoulder a lot long time compared to box or cakes that are three to 5 shots wide. Fortunately, I keep a 5 gallon buck handy with about 3-4 gallons in it for such items and was able to help them out. I think it was Black Dynamite, it's a cool looking firework. Much better then Tommy Gun which they also lit off.
HEY JOEL, NICE VIDS. I WANTED TO GET INTO BUYING FIREWORKS AND PUTTING A SHOW FOR MY FAMILY. AS A BEGINNER IN THE PYRO WORLD. WHAT CAKES ARE GOOD TO BUY AND WHAT SHELLS ARE GOOD. I KNOW EXCALIBER IS THE MOST POPULAR ONE. BUT WHAT OTHER ONE ARE GOOD. AND ALSO, WHAT FUSES ARE GOOD WHEN ATTACHING OTHER FUSES TOGETHER WHEN YOUR COMBINING CAKES AND MORTAR TUBES? THANKS. AND MUCH RESPECTS ON THE PYRO WORLD.
The base of the shell is the lift charge and will be smaller than that of the actual ball shell if that's what you mean. As long as there is not a lot of extra room around the shell, you'll be fine. Extra room around the shell can be a cause for low breaks.
To say that a longer tube would shoot a shell higher in the air sounds reasonable, because a longer tube would keep the shell straighter for a longer time.
The question is whether or not it is a significant difference. Same for 5" shells vs standard 4" shells. To me I seen no difference. Just avoid anything sold by a roadside stand like Shock and Awe, TNT, etc. and get the real 60G canisters and they are mostly the same except the 2017 Excals which stink.
I know this is dangerous. But, I been buying many boxes of Excaliburs every year and I have more than 100 mortar tubes lol. But I been using the same old tubes every year and they all go well. The cardboard one popped inside and it deteriorated during time. I would recommend polyethylene mortar tubes.
Always rather have 12'' over 15'' rather have to much fuse than have to add it. Also your right there is no proof that you get more height on the shells with the longer mortars. I have 50's, 30's, 20's I would hate dragging them around if they were even longer there heavy enough as it is lol.
Hey really want to know if a fiberglass will suppress a explosion error such as a upside down mortar long story short will it through explode sending sharp objects everywhere
HDPE is the way to go if you are buying tubes or racks. Fiberglass is okay, but not as safe. I have fired upside down salutes in both, and the results are always the same. Fiberglass will send chunks flying everywhere. They are lightweight chunks, but still chunks flying. HDPE holds up and flexes. I've never seen a junk of HDPE fly from a mortar.
One thing I'm a little in the dark about: is the 12" taking into consideration the thickness of the plug? Are they actually 13" or 14" depending on if you have a 1" or 2" plug?
@@JoelRobinsonPyrotechnics Got it. So I'm sure a 13" tube w/ 1" plug leaving a 12" internal length wouldn't make that much of a difference but might serve to find a good median to control standard fuse lengths. Looking forward to putting together a 6shot. Thanks for the info!
If you use a 2" tube like ABS there is a huge gap around it where the force can escape. Excalibur HDPE and most fiberglass tubes are 1 7/8" inches (1.87"), not 1.81" (DR9) or 1.91" (DR11).
Platte River Fireworks, mortarsupply.com and PyroBoom are always restocking. I want to build mine while the garage is still warm and not cold like it will be in a few months.
What??? I watched this whole video and didn't get to see the break??? Good info... Epic failure on the climax... Be safe Pyro Brother!!! Happy 4th 2021!!!!!!!!!! Make Some Pretty Loud Noise!!!!
Ken Quesenberry pvc is not good for 2 reasons 1 because it’s not as thick the inside diameter is larger which creates to large of a gap around the shells leading to low breaks because the pressure from the lift charge has too much room to escape 2. If a shell explodes inside pvc it will shatter and send shrapnel everywhere
Depends on the kit the retailer everything. A good guideline is they will have one mortar every six cannister shells so a pack of 24 has 4 mortars. For balls, usually 1 mortar for 12 balls so a 24 pack would have 2 mortars.
Depends, I usually get 4 in my boxes, I have tried, Excal, Golaith and Power Shells and will try some Brother shells soon but do not have any now. I have just use the Excalibur tubes (screwed to treated plywood) for everything but am ready to upgrade to my own build.
Its not a good idea to use a pipe because if the morter explodes in the pipe, it will shatter like a granade with sharp flying peices! So I woundn't. :)
you get more velocity out of a longer barrel... 15" will shoot higher... also, and I'm only half-way through the video, so maybe he says this, but NEVER use PVC
+jerrod hilton No you can't. PVC breaks up into shards when it explodes (which is dangerous), but other tubes like HPE or Fiberglass. Confetti is less dangerous than shards.
No, schedule 40 PVC can not take the heat and will deteriorate. If something goes wrong i will also shatter but you will not get the dangerous shards of fiberglass so it is still better then those in most kits. Another problems is PVC (like ABS) is 2.0 ID not 1.81 or 1.91 and more gas escapes so less lift.
"Yeah I use PVC pipes, my uncle's a plumber and gives them to me. I cut them at a 45 degree angle then stake them into the ground. problem is you can't use them over and over again and you have to plug the bottom." This is incredibly stupid, PVC will shatter and leave sharp shards if you have a shell fail in the tube, the reason people use HDPE is because it is a polymer that will tear but will generally stay as a large piece By using PVC you are endangering yourself and anyone watching your fireworks
I am going to order my rack in 2 weeks... What should I use for a artillery shell that is 2 inches? Dr9 or dr11's? Please awnser now this is serious I gotta get 100 racks and put all of my 30 shot racks and put the ball shells in
I built a shoulder-mounted bazooka for my shells. My greatest fear was a premature detonation of a canister shell, so I made mine with 1/4 inch galvanized steel pipe (welded) with a cap threaded on the back. Have you ever tested that with a canister shell?
There could be something that prevents large bore HDPE that I do not know about. My guess is: cheaper, so they are easier to replace if damaged. Lighter, so you don't break your back during setup.
HDPE is the only way to go.... I have seen a 6" shell explode in a tube and the tube expanded and took the explosion.... The HDPE tube can then be re-used.... you will not see that with any other style.... this tube was 8years old and still took the blast... HDPE only.....
I have had my Excalibur tubes for about 3 years and they have even sat outside without any problems. When I finish my racks I will store those inside. I'm also doing a roman candle rack in perpendicular to the mortars. I used treated plywood and #10 screws.
also he is wrong about fusing the mortar racks lollol cracks me up when fusing a mortar rack you dont want any more than 2 inches MAX of fuse hanging out if you knew what your doing youd know you have to cut the wicks shorter lollol
Can you elaborate as to why you think you need to cut the fuse shorter? Your comment doesn't really do anything other than accusing me on a 9 year old video of saying something incorrectly.
@@JoelRobinsonPyrotechnics all the Xtra fuse sticking up and out the tube are made for consumer and individual use for 1 shot at a time having all the Xtra fuse in a rack when not needed cause if done right only a little bit needs to be fused to the excess fuse that you use to light which will prevent the fuses from jumping and lighting other mortars
For small shells toy can use PVC ABS or HDPE or Fiberglass. The larger shells and a longer tube life HDPE is the one. It is rare to see tubs of HDPE outside of black. The colors in this video is most likely ABS and sold as HDPE.
RElight snowboarding the shards that fly are, but you should be at a safe distance in any case. A can shell lift may be too much for PVC, but balls would be fine, the worry is a flower pot.
+Michael Jobin That just makes no sense. Why use PVC when it can fail at anytime and seriously injure someone? When there are other safer alternatives? That is how people get hurt. You don't know when it's going to fail or where the shrapnel is going to go. Why not just use what you are supposed to use and take the danger out of the equation. Maybe we will have one less injury and one less attempt at local legislators trying to ban fireworks?
+BigMac Fullerton I don't like PVC but ABS casts less than HDPE and Strength ABS piping has a higher impact strength than PVC, especially at lower temperatures. However, ABS can deform under sun exposure. Durability ABS is highly durable with high impact strength. PVC is less durable, as it is designed to be flexible and softer than usual plastics. However, both plastics are resistant to chemical and water degradation.
+Michael Jobin Sound like you know your plastics. Let me ask you this....I just bought a 10 shot rack from Pyroboom with the HDPE tubes and the solid wood caps in the bottom. Can I use these over and over again? How long until they fail? They look like they are pretty thick.
+BigMac Fullerton thy won't if the staples don't rust out. thy should be in a rack with a 2x timber bottom or at least 1/4 in. ply i would go more than that for class C milk create. but HDPE does have a life span so there is a rule of thumb for "shots" but i don't know what that is.
dude was wrong as fuck... 15inch tubes launch your mortars higher Okay!! *FACT* 15 inch tubes also will show more of the mine on your mine shells!! *FACT*
PlatteRiverFireworks has better quality tubes and uses screws but you have to submit an estimate form so you have no clue about shipping costs. PyroDirect does not even have tubes in stock. mortarsupply seems to have them. If you want colors only mortartubes.net supplies them but they want $2.80 instead of the $1.99 - $2.40 of other places.. My DR9's from PyroBoom were great but the DR11 ones all look like a lion chewed on each one. If you want DR9 go with PyroBoom but with DR11 shop around for High Density PolyEthylene tubes.
I like this man. "what would a video be without shooting something off." Very true words

I used DR11 this year for my excals and several of the shells had stars hitting the ground. Never used dr9, but going to look into it for next year.
Power Shells do not fit well in a DR9, the shell fits but the fuse fits too tightly against the side. The Excaliburs do fit a DR9.

They appear to not sell them any more.
Where do you get mortars for that cheap?
What size do you think I should get if I have the trilogy triple break shells 12 kit. I plan on getting the rack too.
If you REALLY want to you can harden up cardboard mortars and reuse them for quite some time. Coat them in side and out with Minwax Wood Hardener. Another method, you can also rinse them with a calcium chloride solution and then when still a little damp coat them with "water glass", sodium silicate. I did it to a batch of cardboard mortars years ago just for a project one rainy day. They still are in fine shape. Or just keep your HDPE or fiberglass kit tubes and forget the hassle!

I tried Power Shells this year but look for any that state 60 grams and you will be happy. 60G = 60G regardless of brand.

One thing I'm a little in the dark about: is the 12" taking into consideration the thickness of the plug? Are they actually 13" or 14" depending on if you have a 1" or 2" plug?

To replace the plug, do you just pop it out and hammer a new one in?
Then pre-drill and screw in 2 or 3 3/4" to 1 1/4" screws each. It's never coming out if you use screws instead of staples.
the card board will be fine as long as they don't get wet and are properly stored back in the day all we hard was paper and steel
If i had for example a 1 3/4'' shell, could i put it into a 2 inch mortar??
You could, but the shell wont shoot nearly as high.
If you use a 2" tube like ABS there is a huge gap around it where the force can escape. Excalibur HDPE and most fiberglass tubes are 1 7/8" inches (1.87"), not 1.81" (DR9) or 1.91" (DR11).
For us people that live in 'Merica
Our larger HDPE tubes (4" to 8") warp over time.

No you can't. PVC breaks up into shards when it explodes (which is dangerous), but other tubes like HPE or Fiberglass. Confetti is less dangerous than shards.

Another problems is PVC (like ABS) is 2.0 ID not 1.81 or 1.91 and more gas escapes so less lift.
Yes, but the issue is cost. The only tubes that are 1.75" are exhaust pipes. If you are rich they would be the ideal material.

Wait?? Mortars are 10 cents? JEEZ I SHOULD'VE BEEN A PYRO BACK THEN!
lmao he said 12" mortars were 10 cents cheaper than 15"
Yeah, who cares! BUT the fuse issues is the real reason to go with 12" tubes.
I am going to order my rack in 2 weeks... What should I use for a artillery shell that is 2 inches? Dr9 or dr11's? Please awnser now this is serious I gotta get 100 racks and put all of my 30 shot racks and put the ball shells in
I got a mix. Both are 2.4" externally so the same racks can hold either.
I built a shoulder-mounted bazooka for my shells. My greatest fear was a premature detonation of a canister shell, so I made mine with 1/4 inch galvanized steel pipe (welded) with a cap threaded on the back. Have you ever tested that with a canister shell?
I thought about it a decide to skip it.
how to lit these mortars
If Fiberglass mortars are worse, why do the professionals use it more?
There could be something that prevents large bore HDPE that I do not know about. My guess is: cheaper, so they are easier to replace if damaged. Lighter, so you don't break your back during setup.
@@JoelRobinsonPyrotechnics Thanks!
HDPE is the only way to go.... I have seen a 6" shell explode in a tube and the tube expanded and took the explosion.... The HDPE tube can then be re-used.... you will not see that with any other style.... this tube was 8years old and still took the blast... HDPE only.....
HDPE is elastic unlike ABS which is actually stronger and more heat resistant but less elastic.
I shot off like 9 ecscalaburs and the mortar it comes with us already messed up
Nathan Ramirez use one of the other 3 mortars that come with the kit
I have had my Excalibur tubes for about 3 years and they have even sat outside without any problems. When I finish my racks I will store those inside. I'm also doing a roman candle rack in perpendicular to the mortars. I used treated plywood and #10 screws.

Be safe guys. I can know you it's dangerous. Please guys

I cant get HDPE because i *LOVE SMELLING THE TUBE AFTER A SHOT WAY TOO MUCH*
U know.. toxic hdpe gasses.. need i say more.
cant you just use a pipe?
HDPE is the best over-all choice. You can use a paper towel tube but do not expect good results.
That doesnt happen man i have shells never happened so you dont need to be scared about that:)
I have had cakes explode but not mortars, yet.
also he is wrong about fusing the mortar racks lollol cracks me up when fusing a mortar rack you dont want any more than 2 inches MAX of fuse hanging out if you knew what your doing youd know you have to cut the wicks shorter lollol
Can you elaborate as to why you think you need to cut the fuse shorter? Your comment doesn't really do anything other than accusing me on a 9 year old video of saying something incorrectly.
@@JoelRobinsonPyrotechnics all the Xtra fuse sticking up and out the tube are made for consumer and individual use for 1 shot at a time having all the Xtra fuse in a rack when not needed cause if done right only a little bit needs to be fused to the excess fuse that you use to light which will prevent the fuses from jumping and lighting other mortars
For small shells toy can use PVC ABS or HDPE or Fiberglass. The larger shells and a longer tube life HDPE is the one. It is rare to see tubs of HDPE outside of black. The colors in this video is most likely ABS and sold as HDPE.
RElight snowboarding the shards that fly are, but you should be at a safe distance in any case. A can shell lift may be too much for PVC, but balls would be fine, the worry is a flower pot.
+Michael Jobin That just makes no sense. Why use PVC when it can fail at anytime and seriously injure someone? When there are other safer alternatives? That is how people get hurt. You don't know when it's going to fail or where the shrapnel is going to go. Why not just use what you are supposed to use and take the danger out of the equation. Maybe we will have one less injury and one less attempt at local legislators trying to ban fireworks?
+BigMac Fullerton I don't like PVC but ABS casts less than HDPE and Strength
ABS piping has a higher impact strength than PVC, especially at lower temperatures. However, ABS can deform under sun exposure.
Durability
ABS is highly durable with high impact strength. PVC is less durable, as it is designed to be flexible and softer than usual plastics. However, both plastics are resistant to chemical and water degradation.
+Michael Jobin Sound like you know your plastics. Let me ask you this....I just bought a 10 shot rack from Pyroboom with the HDPE tubes and the solid wood caps in the bottom. Can I use these over and over again? How long until they fail? They look like they are pretty thick.
+BigMac Fullerton thy won't if the staples don't rust out. thy should be in a rack with a 2x timber bottom or at least 1/4 in. ply i would go more than that for class C milk create. but HDPE does have a life span so there is a rule of thumb for "shots" but i don't know what that is.
whhhat
dude was wrong as fuck... 15inch tubes launch your mortars higher Okay!! *FACT* 15 inch tubes also will show more of the mine on your mine shells!! *FACT*
Actually, it's a very very minor difference. You would likely not even notice from the ground at all.
first lol trolol
Don't visit Pyrodirect.com, Addyracks.com, nor mortarrack.com. Instead, visit the best, which are PlatteRiverFireworks.com and PyroBoom.com.
PlatteRiverFireworks has better quality tubes and uses screws but you have to submit an estimate form so you have no clue about shipping costs. PyroDirect does not even have tubes in stock. mortarsupply seems to have them. If you want colors only mortartubes.net supplies them but they want $2.80 instead of the $1.99 - $2.40 of other places.. My DR9's from PyroBoom were great but the DR11 ones all look like a lion chewed on each one. If you want DR9 go with PyroBoom but with DR11 shop around for High Density PolyEthylene tubes.
