Could you test penetration into a mock standard civilian home with the cavity space filled with spray foam and pea stone gravel? I think you will be surprised by the high density spray foam at home depot mixed with pea stone rocks.😂🎉 thank you!
My closest local range: "No rapid fire! Approved paper targets only!" This guy's range: "Bro, is that an actual canon?! Hell yeah, you shoot all the homemade gyrojet shells you want!"
The rangers come and watch sometimes too! We had to make a call to them to be sure it was safe to bring it there and they checked the bylaws and there's no rules about cannons so they were like "bring it on".
Entry level model rocket motors are very weak in total impulse. The fuel KNO3-C-S is the same as traditional black powder.. Gryo Jet ammo uses smokeless, rumored to have been 16" battleship surplus which had been machined down to fit. A solid lead projectile would hardly see any benefit.
We actually just got a nice metal lathe so now I've got to learn how to use it though but I can hopefully make some nice steel versions and fill it with a real version of solid fuel and see what happens!
What we learned about the first rocket shells is that the rocket doesn’t develop thrust until the projectile is well down range. If the rockets are supposed to spin the projectile to stabilize it, they would need to get the thing spinning before it leaves the barrel. Since they can’t do that, the shell tumbles upon leaving the barrel, usually ejecting the rocket motors, which then fly off in random directions. However on that one shot, they remained in the shell and the shell happened to be pointing upwards when the spin took effect, causing the shell to rocket off into the sky. This obviously didn’t hit the target but it looked pretty cool anyway. It would be interesting to fire one of these shells in true Gyrojet fashion, where it’s just placed in a tube and the rockets are ignited with no powder charge giving it an any additional push. It wouldn’t go nearly as fast as being shot out of a cannon and it probably would have zero accuracy, but it may put on a good show.
I'll see if I can work something up like that... I've got an idea or two to see if I can make them work like that but it might just be a shell and a PVC pipe!
@@TheCannoneer The thing about Gyrojets is that its the rocket motors that are supposed to propel the projectile out of the bore; there isn't supposed to be a primary charge blasting it out of the barrel! If you could just ignite the motors instead of treating it like a cannonball I think you'd get a very different result.
Thanks! It's a super nice range and the people there are always super excited to see the cannon too. It's our summer time range so we might run into you!
pretty sure gyro jet rounds didn't have a powder charge to propel them out of the barrel. it would be interesting to see some launched with just the rocket motors, you'd have a hard time lighting them simultaneously though.
@@TheCannoneer Problem is it was blowing the rockets out of the shell. a much lighter charge, or no charge and ignition with just fuses would have possibly worked better.
@@TheCannoneer you could try loading the gyro jet projectile into a casing. The casing though is not containing any powder but a capacitor bank hooked up to both rockets. Then you cold run the cable connecting the cirquit outside of the fuze hole and just connect it when you want to fire. The cirquit would close lighting both rocket engines at once.
Gyrojet shells great idea if they where to be improved on I would mount a single fuel source inside and have the ignited propelant vented through the vents like in the original ammo... also been thinking since my last post to ya bud.... if you wanted to dragons breath I guess it would be a canister shell of lit magnesium but be very careful as it lieks to start fires
I'll try to see if I can make something similar in the future of metal as we just got a lathe! I think we could safely shoot that at one place at the range. There's a giant fire pit there. Thanks!
They found a bunch of VOC anti-ship missles from the 1600s in indonesia recently. They have an initial propellant charge that fired them out of the barrel, and then a fuze would trigger the rockets after they left the barrel. They were just canisters i think, no fins or anything I think you would just cover the fuze in clay so only the tip ignites
This may be quite difficult to make for a cannon conventional cannon, but tank cannons can fire fin discarding sabot rounds, some sort of kinetic round with fins that pop out and stabilize the projectile would be quite the sight I would think
Hy Mr Cannoneer, Major Rodman ! Your Barrel is sooth or rifled ? Smooth y think . You cannot succesfully obtain great results without a good stabilizer with fins around a solid rod rear. Make an angle on the fins to produce a rotary effect. A rich man in my country in the last 60's had hit a 2 meters by 2 meters target at 4 Km (2.5 miles ) with plain steel shell fins stabilized, machined for him at high price. The caliber was 20 mm smooth and he fired from the top of a hill on the target on the top of an other hill over the city (!)... The lenght of the barrel was around 1 meter , this was a homemade machined cannoon and he was sold 500 € few years ago. Y don't bought it because y have some plastic injection press barrels perfectly reamed in strong steel heat threated and in various caliber, the wall thickness is approximately equal to the bore. This will do perfectly the job and y will make my own model in the futur...
They are pressed fit. You have to use a rubber hammer to get them in there they are so tight I didn't think it needed glue but next time we play with rockets they will get glued!
Your powder charge is destroying the 3D printed shells long before they leave the barrel. From the vidoe you can see that you are mostly shooting out the rocket motors and some chunks of plastic. No FDM print will stand up to those Gs of acceleration. Can you do it again but just use the rocket motors to accelerate the plastic body out of the barrel? Nice video none the less :D
Hmm, so using fins to spin-stabilize rocket propelled grenades and etc since WW2 wasn't "just because" :) Yes, this was a real argument, and yes that was what they claimed... Thanks for the video, I have already rubbed it in his face
On the first 50 yard shot, the shell left the two rockets behind. The two rockets just flew downrange by themselves. I think inertia is causing the shell to just leave the rocket motors behind.
The engines need to ignite inside the barrel, and just before the canon ignites . a quick match may ignite them, or an igniter that lights from the gunpowder going off, but it will need to be put deep into the rocket motor so it lights the propellant quickly.
I feel like figureing out how to put propper ignitors into the motors and then letting _them_ set off the charge vs the other way around would probably go a lot better. maybe there's some small gauge wire that can pass though the fuse hole
Not necessarily, since what differentiates rocket from a bomb is the nozzle. If you first start the rockets you effectively eliminate the nozzle (as it's blocked by the main charge), so I'd presume it would just became part of the main charge.
@@_muody they are getting ignition from the black powder charge right now, if they are surviving that, they will survive properly starting and then having less pressure differential than normal for their startup phase 😂
@@seldoon_nemar But it's not like the black powder is ignited all at once. The projectile will be already in motion and it will be hot gases that will ignite the rockets, which might actually fire already outside of the barrel. If you start the rockets fist, they will build up pressure by themselves when still backed with solid propellant of the main charge. You really don't need much material to contain it and make a firecracker. And the other question is - do they really even survive current configuration?
@@_muody depends on how high the black powder spikes the chamber pressure. it's possible that the internal pressure of the motor could support it. The biggest problem is keeping the grain intact. if it internally fractures, it'll run away, or if the cannon chamber pressure spikes the motor pressure, the case will fail, and like you said, pipe bomb. My hope is that if the motor is started first, it will be structurally stronger against the blast, as it wont be trying to go THOUGH the motor to light it, it'll be fighting against the thrust
Hey cool. Just found your channel, and subscribed . I have 3 cannons, but I'm known for my catapults. Check'm out. I've built over 30 of them, and won a bunch of tournaments, and set some records.
Hi! I've been watching your channel for a few months and overall I really like the idea. I'd like to offer some sincerely friendly observations.

I don't know if that's down to another job or role you play outside the channel? Maybe it's nerves, and who can blame you, it's kind of a stressful position to be in. I'd also like to see you make predictions about whether or not a particular projectile will work - or not - based on your own expertise as the guy who owns the cannon. This might help others who'd like to send in an idea, but need a bit more guidance in making a shell that has a chance of working. You could then follow up with a post-mortem on what went right or wrong, as the case may be. No matter how you proceed, I'll stick around simply because this is a novel and interesting idea.
It's job related haha. I'll try to add in some predictions and things next time we film, I'm always looking to improve. Much appreciated and thanks for keeping up with us!
The Gyrojet rounds were fired by a primer, and had 4 nozzles with the propellant in the round. If you had worked up something where the initial powder charge in the cannon fired off the rocket grain that was built in; it might have worked.
Looks like the light projectile just gets pushed away from the rocket motors, or totally disintegrates in the barrel! Gluing them in and just using very light powder charge might result in more gyro jetting action! 😅
This gyro-jet projectile was a disaster. Not accurate. Not stable. Not durable. I don't recall him saying it, but it looks like he was using a black powder charge to launch the projectile and at the same time ignite the rocket motors. It seems that the black powder charge ignited the rocket motors, but also disintegrated the 3d-printed projectile. The gyro jet pistol only used the propellant in the projectiles. Perhaps try shooting these without the black powder charge.
A couple of things you could try. 1. A minimal charge in the cannon, ideally little more than the priming charge you would be touching off with a slow-match. You only want it to flare in the cannon barrel enough to touch off the rocket motors. 1b. Insert a small amount of rocket fuse into the nozzle of the rocket motors, the powder flare should light that fuse and then the motors. 2. Depending on how large the touch hole is on the cannon, see if you can snake two thin insulated wires into the cannon. Connect those to a pair of electrical igniters for model rockets, then just use a battery to set off the motors.
Someone needs to cast that form in lead. Also that distance is propably too short to show the effects when the conditiones for the desired "rocket supported projectile"-effect are finally met by the design of the projectile.
Not sure if he knows how a Gyro Jet really works. You should not have any propellant to fire the shell out. Only the igniting of the rocket engines is the way to "shoot" the shell.
I do haha It's just a viewer submission design he wanted us to try based on the gyro jet haha. I think if we lowered the powder charge to maybe just ignite the motors we would be on to something.
I think using the rocket propelled cannon projectile you need to ignite the rocket engine first and allow that to touch off the powder. That way the rockets are developing thrust as they are being down the barrel, otherwise the rockets take the shell in whatever direction it happens to be pointing in when they ignite.
From what I've read we have to have the cannon light the projectiles (for legal reasons) but I do think that if we really reduce the powder charge we could be on to something. Just enough powder to light the motors.
You'd be surprised! We've got a viewer submission that took a 100 yard shot fully intact and hit the target. I found it after the impact and you'll see it in a video soon!
Can not say enough about the format of these videos. Hope to see the subscribers double by the end of this month. Everyone remember to like, comment and subscribe.
Give us a Meat Target in the style of Paul Harrell! I'd suggest stacking two or three of them in a line to see if your cannon would penetrate all the way through. Might lend interesting perspective on cannons used against formations of infantry.
Ok! Next time we shoot I'll get something for y'all! We're limited in targets and projectiles depending on the range we shoot at! One range has limited targets and the other has limited projectiles! No pointy things since animals.
@@TheCannoneer For those who haven't seen it before the meat target is four T shirts and a piece of scrap leather (as "skin") wrapped around a pork or ham steak (stand in for Pectoral muscle), rack of pork ribs (to simulate ribs), bag of oranges to simulate lung tissue, Ribs on the back, and backed up by a high tech bullet stop made of old folded up fleece blankets. Almost all pistol and shotgun rounds stop in the target or in the first layer of the "fleece backstop" but I have no doubt your cannon would blow right through a single target!
Oh for sure next time we're playing with the rockets. I had to use a rubber mallet to get them in there so they are incredibly tight so I'm surprised they came out like they did.
Any idea what material the case was made from? I’d been thinking of doing gyrojet using a resin printer for better surface uniformity, but it’s always good to know what material is holding up
It's just PLA. I printed them myself after he sent me the STL. TPU stands up really really well under the pressure of the cannon. I've got another viewer submission that will be coming out that's TPU based.
What powder, and grain are you using? I will need to calculate the pressure in the bore so I can figure out the best material to use for a projectile. Thanks.
@TheCannoneer you have to excuse my anal attentiveness, I reload and turn my own projectiles. I tend to over think everything. I'm looking at making some mini APFSDS rounds for you, but need to know the pressure and velocity so I can figure out the band thickness, fin angle, and sabot material.
There needs to be enough resistance in the barrel to develop thrust. It's why the gyro jet has to overcome the inverse hammer before it even enters the barrel. The round also needs to be more durable so maybe use the lost pla mathod to cast those shapes in bronze about 23 percent larger then turn em down in a laythe to dimension and use rubber cement to keep the motors in and these would work quite a lot better. If you don't have a laythe you could look up bronze shrinkage and cast the sizes apropriately.
Honestly with just a laythe you should be able to drill the motor holes too. It's interesting to me that the motors lit off at all which says this has a ton of potential if your cannon is smoothbore this should make for a particularly steady round and proves the viability of the dual phase boltor round from 40k; powder charge followed by rockets to keep velocity at any range.
@@America_Yea We've played with them with just one but I was a bit worried with two trying to get them to go off together. We will get a working prototype of these soon. It's smoothbore btw. They didn't' introduce rifled cannons until the 1850's and our cannon is a revolutionary war "Robinette" style cannon.
That'd tough, since there's no way to vent the gases in a cannon. And if you leave some free space behind the projectile, it all might be inconsistent and/or ineffective.
What would you like to see us shoot next?
Some more apfsds rounds? You should make the wings out of steel and not plastic so they stay attached
Maybe apcr and apds too
Maybe try square projectiles with a spacer behind them ofc
Discarding sabot rounds

@@User-dc6sm Oh I'm not that skilled!
Seems like they may be failing at the outer wall of the holes for the rocket motors due to how thin the walls are.
I can agree with that 100%!
Gyrojets have one "motor" and 4 outlet ports. It appears 1 estes motor lights and not the other.
Or the whole round disintegrates and the motors just fly off to the four corners of the Earth.

Why are you using a charge behind the gyrojet?! The gyrojet should propel itself, this is a waste of time.
Operation of original Gyrojet is quite different than a cannon, and you can't simply emulate one in the other.
A couple of things you could try.
1. A minimal charge in the cannon, ideally little more than the priming charge you would be touching off with a slow-match. You only want it to flare in the cannon barrel enough to touch off the rocket motors. 1b. Insert a small amount of rocket fuse into the nozzle of the rocket motors, the powder flare should light that fuse and then the motors.
2. Depending on how large the touch hole is on the cannon, see if you can snake two thin insulated wires into the cannon. Connect those to a pair of electrical igniters for model rockets, then just use a battery to set off the motors.
I think you're onto it with the reduced charge just to get it to ignite. I"ll try that!
I would very much like to see a "Low buck cannon build"
How low buck are we talking? lol
Home Depot or Lowes, maybe Ace hardware
@@GUE5TPA55 I'll see what I can do!
Someone needs to cast that form in lead.
Also that distance is propably too short to show the effects when the conditiones for the desired "rocket supported projectile"-effect are finally met by the design of the projectile.
Oh 100% for sure. The non rocket assisted cannonballs will for forever haha.
Not sure if he knows how a Gyro Jet really works.
You should not have any propellant to fire the shell out. Only the igniting of the rocket engines is the way to "shoot" the shell.
I do haha It's just a viewer submission design he wanted us to try based on the gyro jet haha. I think if we lowered the powder charge to maybe just ignite the motors we would be on to something.
@@TheCannoneer 😉.
That might work better 😉😂. Have you seen a Gyro Jet pistol in action? It's a weird invention
@@metern Oh yeah! Brandon's video was super cool, at least my barrel didn't fly off!
@@TheCannoneer That funny as hek 😂
I think using the rocket propelled cannon projectile you need to ignite the rocket engine first and allow that to touch off the powder.
That way the rockets are developing thrust as they are being down the barrel, otherwise the rockets take the shell in whatever direction it happens to be pointing in when they ignite.
From what I've read we have to have the cannon light the projectiles (for legal reasons) but I do think that if we really reduce the powder charge we could be on to something. Just enough powder to light the motors.
tech priests be like
I would try these rounds again with less of a power charge, just enough to ignite the rocket motors and push the projectile out the barrel
I think you're on to sometime. We will try that next time we get to play with the rockets!
3d printing may not have the tolerances for accurate flight. They are cool concepts, but not precise enough to hit the target.
You'd be surprised! We've got a viewer submission that took a 100 yard shot fully intact and hit the target. I found it after the impact and you'll see it in a video soon!
Can not say enough about the format of these videos. Hope to see the subscribers double by the end of this month. Everyone remember to like, comment and subscribe.
Thank you so much!
It looks like the shell is leaving the rocket engines behind to go on their own paths? Maybe a screw-on bottom to hold the engines in?
I think that or some epoxy might do the trick. It took a rubber mallet to drive them in there so I figured they would be ok!
Get the slow mo guys out
I'll reach out to them!
BOLTERS BROTHERS
I still don’t think they will fly strait but maybe glue rocket motors in ?
Next time we play with the rockets for sure! It takes a rubber mallet to hammer them in so I'm surprised that's happening.
Damn, I'm gonna have to bust out the lathe....
Hahaha! Glad I could serve as the inspiration!
Ayyyy! I am hella happy to see you actually make this video after we talked about it really cool 😎
Thanks!
Well it would get someone's attention. That's about it.
Haha! Sometimes that's all that's needed.
i wonder if epoxy would have helped with retention of the rocket motors in the shell
100% for sure would help. It took a rubber mallet to get these pressed in there so I figured they would be ok!
I bet you that would extend the mortar range for better bombardments, yeah?
Oh... that's food for thought. We do have a mortar....
Give us a Meat Target in the style of Paul Harrell! I'd suggest stacking two or three of them in a line to see if your cannon would penetrate all the way through. Might lend interesting perspective on cannons used against formations of infantry.
Ok! Next time we shoot I'll get something for y'all! We're limited in targets and projectiles depending on the range we shoot at! One range has limited targets and the other has limited projectiles! No pointy things since animals.
@@TheCannoneer For those who haven't seen it before the meat target is four T shirts and a piece of scrap leather (as "skin") wrapped around a pork or ham steak (stand in for Pectoral muscle), rack of pork ribs (to simulate ribs), bag of oranges to simulate lung tissue, Ribs on the back, and backed up by a high tech bullet stop made of old folded up fleece blankets.
Almost all pistol and shotgun rounds stop in the target or in the first layer of the "fleece backstop" but I have no doubt your cannon would blow right through a single target!
@@ScoutTerr Thanks for the directions too!
Use a set screw system to hold the rockets in place. Or epoxy
Oh for sure next time we're playing with the rockets. I had to use a rubber mallet to get them in there so they are incredibly tight so I'm surprised they came out like they did.
The enemy would be very pleased to see you pull out a crate of these shells
Right? The first one goes off and they just keep charging after that....
Need to glue the rocket motors into the projectile
For sure! Next time we play with the rockets. It took a rubber mallet to get them in there so I figured they would be ok haha.
The rockets are coming out of the shell on firing.
I'm going to glue them in next time. It took a rubber mallet to hammer them in so I figured they would be fine!
Any idea what material the case was made from? I’d been thinking of doing gyrojet using a resin printer for better surface uniformity, but it’s always good to know what material is holding up
It's just PLA. I printed them myself after he sent me the STL. TPU stands up really really well under the pressure of the cannon. I've got another viewer submission that will be coming out that's TPU based.
We found out TPU worked really well after we'd filmed this one so I'll revisit it in TPU hopefully!
You need a 6 pounder cannon next that would be awesome
100% agree! We're talking about building one if the channel gets big enough!
Dude I hope you get your hands on a high speed camera 🤞
Me too!! I'm saving for one but it's going to take a bit!
The Codex Astartes approves of this experiment. The results are unsatisfactory though and require more effort.
It will be refined!
@@TheCannoneer The Emperor looks benevolently at your determined diligence.
The rockets motors appear to separate from shell.
They needed a rubber mallet to press fit in there so I'm shocked they came out!
I need some artillery...
Agreed! So sorry for the delayed reply! Idk why UA-cam didn’t seem to show me everyone’s reply!
A few more things to iron out, and we'll soon have boltguns for real!!!
We're getting there!
@@TheCannoneer FOR THE EMPEROR!!!!!!!!!
What powder, and grain are you using? I will need to calculate the pressure in the bore so I can figure out the best material to use for a projectile. Thanks.
We usually shoot 400g but we can go up to 800g for some distance shooting. It tends to drop after 75 feet or so on 400g.
@@TheCannoneer what brand powder do you use?
@@NOTSOSLIMJIM Currently Graff and Sons.
@@TheCannoneer standard black powder, or pyrodex?
@TheCannoneer you have to excuse my anal attentiveness, I reload and turn my own projectiles. I tend to over think everything. I'm looking at making some mini APFSDS rounds for you, but need to know the pressure and velocity so I can figure out the band thickness, fin angle, and sabot material.
There needs to be enough resistance in the barrel to develop thrust. It's why the gyro jet has to overcome the inverse hammer before it even enters the barrel. The round also needs to be more durable so maybe use the lost pla mathod to cast those shapes in bronze about 23 percent larger then turn em down in a laythe to dimension and use rubber cement to keep the motors in and these would work quite a lot better. If you don't have a laythe you could look up bronze shrinkage and cast the sizes apropriately.
We actually just got a lathe like last week so I'll be revisiting these I'm sure at some point in metal form haha
Honestly with just a laythe you should be able to drill the motor holes too. It's interesting to me that the motors lit off at all which says this has a ton of potential if your cannon is smoothbore this should make for a particularly steady round and proves the viability of the dual phase boltor round from 40k; powder charge followed by rockets to keep velocity at any range.
@@America_Yea We've played with them with just one but I was a bit worried with two trying to get them to go off together. We will get a working prototype of these soon. It's smoothbore btw. They didn't' introduce rifled cannons until the 1850's and our cannon is a revolutionary war "Robinette" style cannon.
wow! something new )))
Thanks!
That was great brother, I had a chuckle on the tripod hit thank you I need it
Glad I could help! Thats the second one that we've taken down with the rockets....
*subbed 10 seconds in*
Thank you!
The diabolo shape is the way to go. No need for spin stabilisation
Yeah, but rockets are fun :-)
@@_muody but can still be rockets! But can put them straight forward
@@daled4191 True that :-)
I've got a viewer that's sending me a mold for one he made that we will be testing out soon!
@@TheCannoneer amazing, I hope it works well!
I'd like to see it operate as the gyro jet did, on rockets alone.
That'd tough, since there's no way to vent the gases in a cannon. And if you leave some free space behind the projectile, it all might be inconsistent and/or ineffective.
I might do PCV pipe tube and see what happens!
Are you thinking of getting a bigger bore cannon in the future?
100% We're either going to build it entirely or buy a barrel and build the carriage but that's the plan!
@@TheCannoneer Cool i will be here ;-)
