Oh that's very interesting. Thank you for sharing! I did notice that the burst pressure was only about 2/3 of what pvc is, but the way it fails certainly makes it much safer for use. I'll have to look into material availability next time I build one. I've never looked for pressure rates ABS and I imagine it will be tough to find a valve.
I built one similar to that but I invested in a brass valve. I found it in a surplus catalog for about $40.00. I tried a PVC valve but it was too stiff. The brass valve is much easier to open rapidly. It is threaded so I can reuse it if I ever have to replace the PVC portion of the unit. I also used a 1 1/2 to 2 inch reducer on the pressure side and used 2" PVC on the pressure side. This gives me a lot more volume on the pressure side than the barrel. With less than 100 psi I can easily shoot out 200 feet of line and have it lift my throw line container. I typically use 60 - 70 psi for most shots.
Nice work. Those pvc ones aren't great for a quick opening. I bought a $50 1-1/4 brass valve for $4 on clearance. Have no plans but couldn't pass up a deal that good😎
I’ve been waiting for a video on this air cannon build topic. Wow, really well done on the explanation and demonstration! I am a loyal subscriber of your channel and appreciate all your detailed content as you work in the trees! Thank you so much!
Excellent tutorial! It was to the point, very informative on all aspects of build, no stuttering or stammering and very particular about safety! I’ve made a potato gun using hair spray and a lighter but just didn’t know how to do using air pressure? A million Thanks to you!
Cool video, and a win for low budget design! I’m taking note of the ergonomics, as my first build was less than ergo. I ordered a 1in brass threaded butterfly valve and found specs for chamber volume. I pre-fabricated a durable pressure chamber from local plumbing store parts (threaded gas pipe, yes it’s heavy). The butt end has an elbow and two street elbows to mount the Schroeder valve out of harms way. We met up and took my friend’s throw bags to the store to spec a barrel. We chose 1.5in ABS because it looked straight and smooth. Also, ABS is used for impact resistance, and is less brittle than PVC. We glued the 2ft barrel to an ABS threaded reducer, and screwed it into the 1 in brass butterfly valve. ABS drain pipe is not tested for a pressure rating, but we justified it on the steel ball bag projectile leaking a bit of air around the edges, and safety glasses helped too. Our cannon launched a 16oz throw bag very well! With a 12oz bag, we had success using some musket packing techniques (wrap bag in loose wad of porous tissue, rag, etc).

Thats super cool man! I live hearing about other people's versions. Everyone likes to make it a little different and that's great. If I could get pressure rated ABS components, I'd build the whole thing out of ABS. It's much more shatter resistant and therefore much safer in the even of a failure.
I suggest a broom handle or 1/2 or 3/4 inch PVC pipe for a ram to push the bag into the tube. Either ram will be soft and light without risk of scratching the tube.
Had I known a month and a half ago I would have gone this route instead of a giant Slingshot. I think I will eventually build one too. I will probably use 2" on the pressure side like someone else suggested. Thanks for sharing the cannon build.
I followed over here from the other video. I see you are aware of the pressure for that PVC. I work with both steel and PVC, but I think I'll use the PVC for cost. I have a nitrogen tank and regulator. I'll add a gauge and wrap the pressure area, only using about 60 PSI, which is water main pressure. I only need a max of 40 feet or so, to shoot a line onto a roof to pull up a rope, for HVAC tools and parts for stores. I used to tie on a roll of ductape, but my torn shoulder ligaments don't allow for much throwing power.
@@arthouston7361 I’m sure you’ll get what you need to out of that pressure. Wrap isn’t a bad idea at all, just make sure there are not chemical conflicts that will weaken the PVC
Excellent content. I’ve been scrubbing through your videos trying to pick up details about your build, so this is much appreciated. One thought I had that I plan to add to my build of it would be to wrap the pressurized portion of the launcher in a layer or two of duct tape, just as a precaution against shattering or splintering in the event of a failure (thinking colder weather, or brittle pvc after extensive UV exposure). Thanks for putting this together!
@@TreeBuds This is true, however it also probably won't hold air if there are any fractures. Maybe its not a reliable inspection method, but I know that cranes have been built with pressurized tubing to make the development of fractures detectable through the use of a pressure gauge 🤷♂️
Awesome project. The only place I could think you needed more line is in 300 foot red wood trees. I am thinking of a spring and trigger for the valve. Thx for sharing.
Pressure rating on PVC is for liquids, not air. Air is compressible and can cause the PVC to shatter. Best to wear full face protection in case it shatters on you. Air compressors in shops are not allowed to use PVC either schedule 80 or 40 per safe workplace rules. I have seen shrapnel from shattered PVC air imbedded in shop walls, tremendous force that can cause a fatality or loss of eyesight etc. Two common mistakes is using PVC for air compression and using cinder blocks under cars. Hope you guys know that too.
For sure, air pressure and water pressure behave very differently when released rapidly. Can't argue that. I can't comment on shop airlines because I'm not familiar with those regulations, but I do wonder if it has anything to do with their high susceptibility to being crushed by shop equipment or something like that. 1 1/2" schedule 40 pvc like I used here has a burst pressure of 1100 psi, so it seems as though we are staying well below that with a more than a 10:1 safety ratio. If you have a recommendation for a less brittle material, I'd love to hear your thoughts 😊
I thoroughly enjoyed video , I have been in a few tight spots that needs a air cannon , hand toss was difficult and the ones on the market have a cost . thanks so much for a education on a tool that works for you , I may try it .. im just another tree guy .. who enjoys learning about different tools we use to get in to the canopy .. Joe
Cannons are a sweet way to set a line quickly. Climbing and rigging. Especially when you only need a pull line for dropping whole trees they save a lot of time. Made mine from steel pipe bc it was on hand but every crew should have one
I do some non professional climbing myself and use a throwline so far. My neighbor owns a decent soze tree service and has one like this from 1.5 inch threaded plumbing steel and charges is with his trucks compressor but anything could be used to charge it. With air pressure alone there is no way to have it shatter or blow up.
Oh that's nice, I don't have any air brake trucks, but that's a great idea. Tree stuff sold one made out of threaded pipe, does he have one of those or did he make his own?
I built exactly as you describe. However, when I pump it up, its not holding air. I dunked in tub of water, but I can't find any leaks. My schrader valve has a rubber gasket on both the inside and outside of the pvc cap. How should I proceed?
Hmm that sounds interesting. If there aren't any leaks, but no pressure is building, is there a chance you have a problem with your air source? If you're using a bike pump, maybe it has a leak?
Very cool. I need to develop throw line skills to get in the tops of exceptionally high Pined Trees. I mean Pined, with a D. Because I am pining away at the tasks facing me. This air cannon looks good, but I'm going with a sure thing every time. The tried and now true Schling Schott. Patterned similar to the Roman Catapult, when that baby fires, something is coming down.
Hahaa, yeah, I wish there was a better option. Obviously a brass valve could be incorporated, it just adds to the cost and weight quite a bit. Certainly could be worth it though 🤷♂️ Thanks for stopping by!
For air cannons, please use abs (black) or atleast schedule 80. At least for the tank. Pvc breaks into sharp shards, wrapping it in duct tape can mitigate the hard plastic projectiles.
Fair thought. Schedule 80 abs is really hard to find. I do upstanding that is fails in a much safer manner though. That is a valuable thing to consider.
A decade or more ago, some friends of mine built a similar "beer cannon" out of PVC pipe and we used it to launch beer at people at a festival. The beer was put in a coozie with a little parachute on it so nobody got beaned. Unfortunately, after probably 100 shots or so that "300psi" PVC came apart while my friend was holding it. It wasn't cold or anything. He was lucky and didn't need hospitalization but it left a huge nasty purple bruise all down his torso and on one arm. If the shards had gone a different direction it might have been tragic.
@zaccheus We where using a compact bicycle pump, no pressure guage but my experience with them is that they get very hard to pump after about 70psi, so right around there. Point being I would never again assemble a pressure vessel using PVC pipe. For about the same money you can assemble a much better air cannon using a 2.1 gallon "bead seater" from amazon which is both safer and more effective, having a proper steel tank, trigger, and overpressure relief.
Try putting foam pipe insulation around it. It might soften the kickback and prevent it from breaking if you drop it. It might also stop or slow down the shrapnel if it explodes 🤯
Instead of a single tube ,put a small one inside of a bigger one. This gives extra thickness Wrap the small tube with exhaust bandages to make a super strong barrel. Or just use thick metal pipe. Instead of a bike pump use a gas canister to load the chamber through a tyre valve. Is the throw weight aerodynamic ? If not why not Make a cardboard rocket cone with a nail in the centre like a dart. The rocket cone should be a tight fit in the barrel.
Just built one of these following your design. 55psi launched a 10oz throw weight 110 feet skyward. I was considering making another ... but let me know what you think about these design changes ... Rather than being shoulder-fired, might make it ground supported with a single long compression tube. Then add a 45-degree coupling before the vale to make aiming easier (and likely where I would install the value). This way it rests on the ground, not on your shoulder for better balance. And also keeps all of the compression areas away from your face during the sighting. To make it more portable, the pressure site could have a compression coupling to allow it to be spilt in half. Or the barrel side could be set up as detachable. Instead of gluing the barrel to the value, just drill a small pinhole and slide a nail across to hold it. That seal does not need to be super airtight. Thoughts! And thanks for the great content. Btw, I'm a self-taught climbing homeowner, kinda like one guy you mentioned in a recent video. I have an acre of trees to maintain.
That's great man! I love to hear about people who care enough about their trees to take it into their own hands. Those all sounds like cool modifications. The beauty of the whole thing is that everyone always ends up with their own twist. I have some friends who all made their own and none of them look alike. Thanks for sharing!
@@zaccheus Well my V1 looks just like yours :). Now I need to put it to real use. But I only find time to climb once every few months. I do have all the professional gear and climb with an Echo 2511T. Just rarely have the good fortune to have someone to run the rigging lines so I figure out ways to do that solo, usually with natural crotch rigging. Now i would love to climb and learn from a pro some time. I'm in MD. I also follow @Metaspencer, in central NY, maybe you do too.
@CoolGen10 Yeah, I've seen some of his stuff. He's also kind enough to comment on my videos occasionally. Find help is hard and doing work solo is also difficult. I've been able to use different friends I have in the industry, but they all come at a price 🤷♂️
Absolutely worth a try. I have a client that I maintenance short wave antenna wires that are hung in trees. I think you could use this to do it in the right situation
As André said, it's a throwline and weight. The weight is a canvas bag with lead shot in it. I believe a quick search on Amazon will yield something for you. I'll add a link to the description too.
Great engineering!!! This kinda reminds me of the “potato guns” with bigger pvc to fit a potato, and you would spray some highly flammable spray in behind the potato, screw the end cap on tight then light the charge through a small hole drilled into the charge area behind the potato. Like lighting a real 18th-19th century cannon that uses black powder.
@Rockingruvin The best ignition source for potato gun is a Push Button Piezo Igniter. I’m sure there would be some scaling down needed. The average diy potato gun is usually capable of launching a potato 4 to 500 feet.
If it is buried in the ground with an air pocket at the end at 200 psi then it is an irrigation system. If it is out of the ground it is a gun and must be treated as a gun. With all the safety precautions applicable including storing it. I have seen shards of PVC pipe fly over 500 feet. You do not want that cannon damaged in your toolbox.
I'm not sure what you are referencing when you say rubber... spring loading the valve sounds like a great idea. I'm not sure the plastic valve would handle it really well, but it's a great idea for a brass valve.
@@zaccheus a big rubber band under load with a catch of some sort on the handle... it would serve the same purpose as you pulling on it essentially.... if it were linear with the barrel I dont think it would cause the valve to reach the limit but theres only one way to know for sure
I have seen those units! A pretty good idea for sure. I'm not sure I'd feel comfortable using that on something filled with air pressure right next to my face. It might be fine, and I'm sure it would he fine for drain applications, but for this scenario, I really want 100% certainty that it's the best it can be
Thanks for sharing your design and this video. Like viewers I built a different version about 10 years ago. However I prefer your design. Except I attached a fishing reel to the barrel to feed the a line. 73 Steve AA4SH
Id love to use schedule 80, but I don't know where to find it with a pressure rating. Most pipe is sized by internal diameter so I would imagine the same sizes would work, but who knows 🤷♂️
@Zaccheus Ah Thank you. In my research for a 1-1/2 inch barrel I've seen Guys use 10 12 14 and 16 oz bags. I guess it just has to be heavy enough To continue to fall after it's up over the branch, I'm kind of working that out right now.
@CRUSH* VAPOR That's definitely my biggest struggle with the 12 Oz bags. If I use any of the heavier ones, I have a hard time keeping things on target.
@@zaccheus I started with an 8 oz. weight, now up to 13 oz., it just barely pulls the rope down over the branch. I'm using cheapo 1/4" Hollow Braided Polypropylene Rope, BTW I'm using a homemade weight made of an eyebolt, washers and a wood plug made with a hole saw. Haven't had trouble keeping on target, maybe the weight bags you buy have aerodynamic problems being shot from a cannon. Your vids are very interesting!
I would rebuild the stock and handle or pressure side of the gun out of galvanized pipe Zacceus! You can use a coupling and a threaded reducing bushing to get down to 1/4 inch pipe thread for the schrader valve. Or just tap threads into a cap with a 1/4 inch Pipe tap Do it before you use it again man! Just say you have a hundred psi in there and drop and bust it. It could send sharp plastic pieces flying like shratnel with ballistic force. I'd use a brass 1/4 turn ball valve as well. I don't know much about climbing yet but I grew up in the pipe business!😀 I have twice now had to get out of a broke down bucket truck. LOL! I was stuck for 3 hrs yesterday till my brother got a 40 ft ladder and some tree climber friends to bring some rope to tye me off if something went wrong while going down the ladder which only reached a foot onto the bucket. So aggravating having a bucket truck available to trim some dangerous pecan limbs off the house and it keeps failing.
Keep in mind water pressure is different than air pressure. You can get yourself hurt real fast pressurizing PVC with air. 60 psi max....and that may be pushing it.
I see what you're saying, but pressure is pressure all the same. 60psi is still 60psi no matter is its made by air, water, or shrinking, the pipe around a steel bar. What's different is when the pressure is release by vessel failure. Air is a spring so it propels pieces with velocity. Water is not and so it doesn't.
@zaccheus Ha !! Schooled Him !! 👍 It's hilarious how people read someone else's comment, take it as Fact and then reuse it with out Fact Checking and actually learning the principles behind it. I would of loved if you could of said in life.. Oh yeah, why ? Uh uh because I read it.. 😆
@@zaccheus I think thats a great idea...2 elbows instead of 2 caps... would be a lot more solid... you could even go crazy and 45 the barrel for extra support... not pressurized of course you could just glue the fittings on the surface
@@jbbolts True, true, it would add volume aswell. It might be tough to Fina place to out the schrader valve, but that might not be too hard if a problem to solve
Aw man, I wish I could help. I can't handle the liability of building one for someone else. If it ever did blow up, I'd be responsible and I am not equipped to accept that liability. There is a version commercially available called the APTA I'll link it here: www.treestuff.com/apta-air-powered-tree-access/
Really cool, I'm looking to see if it's possible, a weapon like the one that appears in the movie Fast and Furious 6, the one that sticks into the wall hahaha it's something like a harpoon
@@RC-Heli835 yeah! The 12oz seems to be a nice balance of factors. It not too heavy to get really high, but it still seems to have enough weight to come down once it's over a branch
@@zaccheus Cool! I just ordered enough stuff to climb with a blakes hitch. Have to wait on a climbing device. Finally got the broke bucket truck out from over my house yesterday.
@@zaccheus No one could cross reference the number on the pump but a place called Force America who specializes in hydraulics matched it up for me for 440 bucks! Come to find out I had run one tank of gas in an Echo top handle 14 in chainsaw that I had met someone to buy at home depot at day break. When it ran out of gas I went to take the bucket down for gas and it was game over. What had occurred was a check valve bolted right onto the pump had failed and let its check ball go to the very next fitting which was actually screwed into the check valve. A tee that goes to idle up the throttle hydraulically when pressure is made by the pump. That ball was stuck in the tee with some plastic trash behind it. When I first found the damaged chk valve I got the spring out then but it took us a while to run down a pump and I forgot to look for the rest of the trash and ball from the check valve. So you guessed it my new pump immediately failed. The check ball had the system so completely locked down nothing was circulating. Luckily I found a new pump on ebay identical to the new failed one for 160.00 bucks. So yea all in all I'd say we have a thousand bucks in it and it still needs a starter. The start will start the truck about every 18 trys. Also a solenoid for the backup 12V DC hydraulic motor/pump to make it work again. Also after the pump started leaking, a failing relay cutting the PTO on and off broke the shift fork on it as well. So had to replace that! Because of that I bypassed all the electric and make it air only PTO. Too many failure points on electric to leave man stuck in bucket!
@@zaccheus I lucked up and got 12 Kong Carabiners on Fleabay for 75 bucks. 50 Kn Carbin steel! 150 dollar pelican rope locally. Spent 49 bucks for 220 feet of Vevor 1/2 inch rope on amazon. Its so stiff that a blakes hitch doesn't hold at all on it so gonna use it to zip with. 13 buck hand saw from the hardware. And a few other things. Really 3500 bucks would get a man up in the tree with just the basic Arbor rated gear. You need so much stuff just to get started man. I got the SOB climbing saddle off amazon for 63 bucks and like it ok just wish it had a shoulder harness. That's a 10th of what a Monkey Beaver 2.0 cost's but it works and seems well made. My 11 oz throw bag fits the launcher way too loose! It barely shoots to the lowest branches. I figured it up my air chamber has less than half the cubic inches that yours does so gonna have to get a larger air chamber.
I cannot say, I'm not a plumber or engineer. I don't feel.comfortable putting more than 100 psi in it. But even that much pressure could severely injure you if it broke.
@zaccheus ive been working on something similar but from a reverse perspective. Your solution fires the throw line to the target/shore. First my problem) when going out boating alone and coming back in, its a hassle and a race when docking the boat to try and tie off the lines both at the front and back, to prevent the boat from veering its ass outwards, depending on winds and water currents. Solution) what if when you came in with the boat, the lines would fire from.the shore into the boat, and all youd need to do is tienit off
@grdnsherman mmm, I'm sorry to hear that. It must be a really tight weight. Maybe try just sitting it on top of tue barrel and giving the other end of the cannon on the grass. It's something that doesn't push in very well. It kind bunches up if you push on it
Back in the day we made potato cannons and in the early days of utube had a video of us on a job site in a basement shooting a hard hat and canned vegetables with our potato cannon paid for having fun ... I'm making a mini 1 now for my throw bag ... I'm a electrician but hear with wood amd drop trees for free so I can have the wood
All guages loose psi unless you have one integrated into the system. The thing thay mayyer the most is that it's fairly consistent from one cycle to the next. It's okay if 10 psi escapes, as long as 10 psi escapes every time.
Screw that! I have a 6ft long spud gun i made for a science fair project! 6inx12in combustion chamber, reduced down to a 2inx5ft barrel. And a BBQ igniter for spark. Lol I dont even mess with throwline, i tie my climbline to the bag and send her on her way! Lol im jk. Im not that slow in the head. It would be fun to test it tho! To see if a regular spud gun that uses fuel/spark can out do a similar sized pneumatic spud cannon. I know ive launched potatoes a tad over 300yrds with it. Its a bit temperamental tho, because if you dont get enough oxygen inside the chamber. It wont ignite properly or at all really. But it can be a lot of fun! My science fair project was to find a way to simulate how a combustion engine works. Have you, i think i may have been in 8th grade tops. So it was pretty clever for a 13yr old to do. Basically the potato represents the piston, combustion chamber represents just that. And the screws i had in the sides of the combustion chamber represented spark plugs,, and the ignitor represented an ignition system. Unfortunately, i had to do it via a video. Since school wouldnt allow it on school property. Lol But it was a very fun project. Forgive me for going off topic. Just thought some may be curious what my project was...
Lol, I thought about going that route. It's obviously a little hard to regulate. The pneumatic version here isn't perfect either, but you can atleast work with 10 lb increments
Not at all! I am located in North Canton. Looks like I'm about three hours from you. Not too far to go if you ever need a climber for a day or more. Will you he attending the Paul Bunyan show?
@@zaccheus you are right. My pal told me about it and for some reason we thought it was October 1-2. We will for sure be there. I am assuming you are talking about Cambridge Ohio??
What if it was just a single pipe? Less to fail and you launch it on the ground like a grenade launcher? Less accurate but less to fail and safer. 🤷♂️ I might try building one.
You could definitely try that. I think the accuracy is a big part of what makes this handy, but I imagine you could get good with it in any form if you practiced. It might be good to increase the pipe size if you just go straight with it. If you don't have very much volume behind the valve, you might have to use a higher pressure to get the same results.
Might be safter with metal, though it's bad when it explodes too. I'm not sure using an unregulated pressure source will work all that great for throwline stuff though. Sometimes 400ft is 300ft too much 😅
What? A vertical grip on a polymer stock? That might need to be registered as an "Assault" air cannon... Nevermind, I'm from the Vampire State east of Ohio and have been marinating in overbearing gov't regulations too long. 😂
@@belowfray5251 well I’m sure that was a one time experience for you. I have a video about building a black powder cannon: ua-cam.com/video/Ewr2Ec0pXZg/v-deo.html
Dude how in the can you comment on my page saying I don't know anything about safety and you build an air cannon out of PVC pipe that isn't rated to anywhere near the PSI you're putting through it. Smart kid real smart 😂😂😂
I made one out of a bead blaster for tires. its basically a metal tank with a 1 1/2" valve that you fill with air to seat tubeless tires. Same principle as your except you set min on the ground and aim it like a cannon...... and with a 5' foot long barrel...... lol, watch out. It will launch that bag the length of a football field.
Hmmmm, I'm thinking that increasing the size of the tubing on the air storage tank would make the throw ball go a lot faster and higher 🤔 I won't do the extra 90° and T junction as those would weeken the system...... I'll probably make some handles that can clamp around the tubing...... maybe launch it RPG style and put some sights on it of some sort 🤔🤔🤔 I don't really need one, but just the possibility of such a monster just strokes the "Deadpool" parts of my mind. Don't worry, with the larger air container I won't need to go that high on the pressure, but I might try a bit more once I have confidence that I'm not going to kill myself 😁
That's also a viable option. The only think I don't like about the APTA is that the compression chamber is smaller so it requires more pressure and it's just plain heavy.
Abs instead of pvc. Abs will rupture if cracked or over pressured. Pvc will explode like grenade. m.ua-cam.com/video/D8C_gZls6v8/v-deo.html
Oh that's very interesting. Thank you for sharing! I did notice that the burst pressure was only about 2/3 of what pvc is, but the way it fails certainly makes it much safer for use. I'll have to look into material availability next time I build one. I've never looked for pressure rates ABS and I imagine it will be tough to find a valve.
You could wrap it in cloth.
@@mightyconker3903 I've thought about that before. Even some good duct tape would probable help contain the shards I would think
Commonly available ABS pipe is designed for drain service, not pressure service. Only use pressure rated materials.
haven't been able to find pressure rated ABS. I see people advocating for its use, but it does not seem readily available.
I built one similar to that but I invested in a brass valve. I found it in a surplus catalog for about $40.00. I tried a PVC valve but it was too stiff. The brass valve is much easier to open rapidly. It is threaded so I can reuse it if I ever have to replace the PVC portion of the unit. I also used a 1 1/2 to 2 inch reducer on the pressure side and used 2" PVC on the pressure side. This gives me a lot more volume on the pressure side than the barrel. With less than 100 psi I can easily shoot out 200 feet of line and have it lift my throw line container. I typically use 60 - 70 psi for most shots.
Thats all super great info, thanks for sharing! That was a super sweet deal you got on that valve!
Sprinkler valves modified for pneumatic control instead of electrical solenoids actuate much faster than ball valves.
Nice work. Those pvc ones aren't great for a quick opening. I bought a $50 1-1/4 brass valve for $4 on clearance. Have no plans but couldn't pass up a deal that good😎

I suggest a broom handle or 1/2 or 3/4 inch PVC pipe for a ram to push the bag into the tube. Either ram will be soft and light without risk of scratching the tube.
Had I known a month and a half ago I would have gone this route instead of a giant Slingshot. I think I will eventually build one too. I will probably use 2" on the pressure side like someone else suggested. Thanks for sharing the cannon build.
Sure thing! Might make sense to use a 2" valve too for better flow. Although maybe the weight would try to get stuck behind the reducer...

Excellent content. I’ve been scrubbing through your videos trying to pick up details about your build, so this is much appreciated. One thought I had that I plan to add to my build of it would be to wrap the pressurized portion of the launcher in a layer or two of duct tape, just as a precaution against shattering or splintering in the event of a failure (thinking colder weather, or brittle pvc after extensive UV exposure). Thanks for putting this together!
No problem, duct tape or gorilla tape wrapping seems to be a common thought. Probably a worthwhile idea. It will even prevent UV exposure
if it is covered in tape you cant inspect it to see fractures
@@TreeBuds This is true, however it also probably won't hold air if there are any fractures. Maybe its not a reliable inspection method, but I know that cranes have been built with pressurized tubing to make the development of fractures detectable through the use of a pressure gauge 🤷♂️
Awesome project. The only place I could think you needed more line is in 300 foot red wood trees. I am thinking of a spring and trigger for the valve. Thx for sharing.
@@MrSmith-qu4nx I’d be sweet to engineer a trigger system. Yanking the handle does produce some accuracy problems
Pressure rating on PVC is for liquids, not air. Air is compressible and can cause the PVC to shatter. Best to wear full face protection in case it shatters on you. Air compressors in shops are not allowed to use PVC either schedule 80 or 40 per safe workplace rules. I have seen shrapnel from shattered PVC air imbedded in shop walls, tremendous force that can cause a fatality or loss of eyesight etc. Two common mistakes is using PVC for air compression and using cinder blocks under cars. Hope you guys know that too.
For sure, air pressure and water pressure behave very differently when released rapidly. Can't argue that. I can't comment on shop airlines because I'm not familiar with those regulations, but I do wonder if it has anything to do with their high susceptibility to being crushed by shop equipment or something like that. 1 1/2" schedule 40 pvc like I used here has a burst pressure of 1100 psi, so it seems as though we are staying well below that with a more than a 10:1 safety ratio. If you have a recommendation for a less brittle material, I'd love to hear your thoughts 😊
Plastic pop bottles
Exactly what I was looking for thanks! Heading into the tropics where I need to get a line 100ft up
This thing will do it! Good luck with your trip!
I thoroughly enjoyed video , I have been in a few tight spots that needs a air cannon , hand toss was difficult and the ones on the market have a cost . thanks so much for a education on a tool that works for you , I may try it .. im just another tree guy .. who enjoys learning about different tools we use to get in to the canopy ..

Sure thing! I hope it works well for you. Be safe out there!
Cannons are a sweet way to set a line quickly. Climbing and rigging. Especially when you only need a pull line for dropping whole trees they save a lot of time. Made mine from steel pipe bc it was on hand but every crew should have one
I'd have to agree, they can be a big time saver if used correctly. You certainly don't have to worry about that thing coming apart!
Good idea to duct tape the pressure side in case it blows up under pressure.
I do some non professional climbing myself and use a throwline so far.
My neighbor owns a decent soze tree service and has one like this from 1.5 inch threaded plumbing steel and charges is with his trucks compressor but anything could be used to charge it.
With air pressure alone there is no way to have it shatter or blow up.
Oh that's nice, I don't have any air brake trucks, but that's a great idea. Tree stuff sold one made out of threaded pipe, does he have one of those or did he make his own?
im very impress with what you made!!! the video was wonderful and very informational. thank you
@@erw9604 glad to hear it!
I built exactly as you describe. However, when I pump it up, its not holding air. I dunked in tub of water, but I can't find any leaks. My schrader valve has a rubber gasket on both the inside and outside of the pvc cap. How should I proceed?
Hmm that sounds interesting. If there aren't any leaks, but no pressure is building, is there a chance you have a problem with your air source? If you're using a bike pump, maybe it has a leak?
Very cool. I need to develop throw line skills to get in the tops of exceptionally high Pined Trees. I mean Pined, with a D. Because I am pining away at the tasks facing me. This air cannon looks good, but I'm going with a sure thing every time. The tried and now true Schling Schott. Patterned similar to the Roman Catapult, when that baby fires, something is coming down.
PVC ball valves are the bane of every maple farmer's existance. They just don't last.... super interesting... reminds me of potato gun days...
Same thing basically but easier to judge we’re your shooting
Hahaa, yeah, I wish there was a better option. Obviously a brass valve could be incorporated, it just adds to the cost and weight quite a bit. Certainly could be worth it though 🤷♂️ Thanks for stopping by!
There are some strong laser pointers that are small that would easily mount to that pressure gun for aiming if needed
For air cannons, please use abs (black) or atleast schedule 80. At least for the tank. Pvc breaks into sharp shards, wrapping it in duct tape can mitigate the hard plastic projectiles.
Fair thought. Schedule 80 abs is really hard to find. I do upstanding that is fails in a much safer manner though. That is a valuable thing to consider.
A decade or more ago, some friends of mine built a similar "beer cannon" out of PVC pipe and we used it to launch beer at people at a festival. The beer was put in a coozie with a little parachute on it so nobody got beaned. Unfortunately, after probably 100 shots or so that "300psi" PVC came apart while my friend was holding it. It wasn't cold or anything. He was lucky and didn't need hospitalization but it left a huge nasty purple bruise all down his torso and on one arm. If the shards had gone a different direction it might have been tragic.
@@ackattacker wow, that sounds dangerous on a number of levels. What pressure were they using and how were they pressurizing it?
@zaccheus We where using a compact bicycle pump, no pressure guage but my experience with them is that they get very hard to pump after about 70psi, so right around there. Point being I would never again assemble a pressure vessel using PVC pipe. For about the same money you can assemble a much better air cannon using a 2.1 gallon "bead seater" from amazon which is both safer and more effective, having a proper steel tank, trigger, and overpressure relief.
@ excellent that’s, thank you
Try putting foam pipe insulation around it. It might soften the kickback and prevent it from breaking if you drop it. It might also stop or slow down the shrapnel if it explodes 🤯
That's a great idea, thanks for the suggestion!
Instead of a single tube ,put a small one inside of a bigger one.
This gives extra thickness
Wrap the small tube with exhaust bandages to make a super strong barrel.
Or just use thick metal pipe.
Instead of a bike pump use a gas canister to load the chamber through a tyre valve.
Is the throw weight aerodynamic ?
If not why not Make a cardboard rocket cone with a nail in the centre like a dart. The rocket cone should be a tight fit in the barrel.
Just built one of these following your design. 55psi launched a 10oz throw weight 110 feet skyward. I was considering making another ... but let me know what you think about these design changes ... Rather than being shoulder-fired, might make it ground supported with a single long compression tube. Then add a 45-degree coupling before the vale to make aiming easier (and likely where I would install the value). This way it rests on the ground, not on your shoulder for better balance. And also keeps all of the compression areas away from your face during the sighting. To make it more portable, the pressure site could have a compression coupling to allow it to be spilt in half. Or the barrel side could be set up as detachable. Instead of gluing the barrel to the value, just drill a small pinhole and slide a nail across to hold it. That seal does not need to be super airtight. Thoughts! And thanks for the great content. Btw, I'm a self-taught climbing homeowner, kinda like one guy you mentioned in a recent video. I have an acre of trees to maintain.
That's great man! I love to hear about people who care enough about their trees to take it into their own hands. Those all sounds like cool modifications. The beauty of the whole thing is that everyone always ends up with their own twist. I have some friends who all made their own and none of them look alike. Thanks for sharing!
@@zaccheus Well my V1 looks just like yours :). Now I need to put it to real use. But I only find time to climb once every few months. I do have all the professional gear and climb with an Echo 2511T. Just rarely have the good fortune to have someone to run the rigging lines so I figure out ways to do that solo, usually with natural crotch rigging. Now i would love to climb and learn from a pro some time. I'm in MD. I also follow @Metaspencer, in central NY, maybe you do too.
@CoolGen10 Yeah, I've seen some of his stuff. He's also kind enough to comment on my videos occasionally. Find help is hard and doing work solo is also difficult. I've been able to use different friends I have in the industry, but they all come at a price 🤷♂️

@@floridasaltlife thanks!
Great video. Thank you for sharing. What diameter pipe please?
I found 1.5" to work well. I just took my throw weight to the store with me and test fit different sizes until I found one that worked.
Great content but what is the item shot from the cannon? and where do I get it?
It is a throwline with a weight (throwbag) attached to it. Found in any arborist supply store.
As André said, it's a throwline and weight. The weight is a canvas bag with lead shot in it. I believe a quick search on Amazon will yield something for you. I'll add a link to the description too.
Great engineering!!! This kinda reminds me of the “potato guns” with bigger pvc to fit a potato, and you would spray some highly flammable spray in behind the potato, screw the end cap on tight then light the charge through a small hole drilled into the charge area behind the potato. Like lighting a real 18th-19th century cannon that uses black powder.
Hahah, it's very mucjbthe same. I'd be lying if I said I had never tried shooting various fruits and vegetables out of it 😂
@Rockingruvin
The best ignition source for potato gun is a Push Button Piezo Igniter.
I’m sure there would be some scaling down needed. The average diy potato gun is usually capable of launching a potato 4 to 500 feet.
If it is buried in the ground with an air pocket at the end at 200 psi then it is an irrigation system. If it is out of the ground it is a gun and must be treated as a gun. With all the safety precautions applicable including storing it. I have seen shards of PVC pipe fly over 500 feet. You do not want that cannon damaged in your toolbox.
did you consider rubber or spring loading the valve? You might get a bit more power out of it.. thanks man!
I'm not sure what you are referencing when you say rubber... spring loading the valve sounds like a great idea. I'm not sure the plastic valve would handle it really well, but it's a great idea for a brass valve.
@@zaccheus a big rubber band under load with a catch of some sort on the handle... it would serve the same purpose as you pulling on it essentially.... if it were linear with the barrel I dont think it would cause the valve to reach the limit but theres only one way to know for sure
No bag size
My guess 12oz
Do you trust the pump gauge to not measure the pressure?
Yes, it's not necessary to be super accurate with the pressure. Pulling the handle consistently is a much bigger factor.
Thank you so much my man. Awesome content. When do you believe you’re going to post your next take down video?
I'm going out to film one tomorrow! I haven't seen the tree yet, but I hear it's a big dead elm 😊 should see a video later this week!
@@zaccheus looking forward to it tree brother! Stay safe as always
@@gormaionem4648 Thanks!
If you need to reuse fittings buy the drill bit kit designed to auger out the fittings back to original size.
I have seen those units! A pretty good idea for sure. I'm not sure I'd feel comfortable using that on something filled with air pressure right next to my face. It might be fine, and I'm sure it would he fine for drain applications, but for this scenario, I really want 100% certainty that it's the best it can be
Thanks for sharing your design and this video. Like viewers I built a different version about 10 years ago. However I prefer your design. Except I attached a fishing reel to the barrel to feed the a line.
73 Steve AA4SH
Oh the finishing reel component is a sweet idea! Did that work out pretty well?
Schedule 80 pipe and fittings are available that are stronger. Smaller inside dimensions would require larger size pipe.
Id love to use schedule 80, but I don't know where to find it with a pressure rating. Most pipe is sized by internal diameter so I would imagine the same sizes would work, but who knows 🤷♂️
I ended up spending $110 on parts. Galvanized meta parts that contains the air, PVC barrel, and brass ball valve between the two for lever.
Very valuable information, thanks for sharing!
Great video, How heavy is the weight bag, brand name?
Thx.
It's a 12oz weaver throw weight. I think 14oz bags will fit too, I haven't tried any other sizes.
@Zaccheus Ah Thank you.
In my research for a 1-1/2 inch barrel I've seen Guys use 10 12 14 and 16 oz bags.
I guess it just has to be heavy enough To continue to fall after it's up over the branch, I'm kind of working that out right now.
@CRUSH* VAPOR That's definitely my biggest struggle with the 12 Oz bags. If I use any of the heavier ones, I have a hard time keeping things on target.
@@zaccheus I started with an 8 oz. weight, now up to 13 oz., it just barely pulls the rope down over the branch.
I'm using cheapo 1/4" Hollow Braided Polypropylene Rope,
BTW I'm using a homemade weight made of an eyebolt, washers and a wood plug made with a hole saw.
Haven't had trouble keeping on target, maybe the weight bags you buy have aerodynamic problems being shot from a cannon.
Your vids are very interesting!
So can you recommend a better throwing line that's not too expensive? Thanks
Hello can I use this cannon freely in the field or is it perhaps iligal after all
I've never had any real trouble with legalities. A ranger in a national park told me it was a gray area for use in the park, but thay was it 🤷♂️
I would rebuild the stock and handle or pressure side of the gun out of galvanized pipe Zacceus!
You can use a coupling and a threaded reducing bushing to get down to 1/4 inch pipe thread for the schrader valve.
Or just tap threads into a cap with a 1/4 inch Pipe tap
Do it before you use it again man! Just say you have a hundred psi in there and drop and bust it. It could send sharp plastic pieces flying like shratnel with ballistic force. I'd use a brass 1/4 turn ball valve as well.
I don't know much about climbing yet but I grew up in the pipe business!😀
I have twice now had to get out of a broke down bucket truck. LOL! I was stuck for 3 hrs yesterday till my brother got a 40 ft ladder and some tree climber friends to bring some rope to tye me off if something went wrong while going down the ladder which only reached a foot onto the bucket.
So aggravating having a bucket truck available to trim some dangerous pecan limbs off the house and it keeps failing.
RC-heli: trimming Pecan limbs. From the hurricanes in south Georgia? What kind of bucket truck system is it? Altec?
Keep in mind water pressure is different than air pressure. You can get yourself hurt real fast pressurizing PVC with air. 60 psi max....and that may be pushing it.
I see what you're saying, but pressure is pressure all the same. 60psi is still 60psi no matter is its made by air, water, or shrinking, the pipe around a steel bar. What's different is when the pressure is release by vessel failure. Air is a spring so it propels pieces with velocity. Water is not and so it doesn't.
@zaccheus Ha !! Schooled Him !! 👍 It's hilarious how people read someone else's comment, take it as Fact and then reuse it with out Fact Checking and actually learning the principles behind it.
I would of loved if you could of said in life.. Oh yeah, why ? Uh uh because I read it.. 😆
would be better to connect the 2 handles to increase longevity and cracking
Oh that's a good thought. I have experienced a failure there, but anything is possible!
@@zaccheus I think thats a great idea...2 elbows instead of 2 caps... would be a lot more solid... you could even go crazy and 45 the barrel for extra support... not pressurized of course you could just glue the fittings on the surface
@@jbbolts True, true, it would add volume aswell. It might be tough to Fina place to out the schrader valve, but that might not be too hard if a problem to solve
@@zaccheus Perhaps a y fitting with a cap for the schraeder valve somewhere inline is what came to my mind 👍
Nice video, if you shot 188 feet of line out, half was up, half was down. Trajectory. So you shot 90’ high or so
Thanks!
How much u charge to build one got drone stuck in a tree shoulder hurts from tossing my throw line. Seriously I pay u to build one for me
Aw man, I wish I could help. I can't handle the liability of building one for someone else. If it ever did blow up, I'd be responsible and I am not equipped to accept that liability. There is a version commercially available called the APTA I'll link it here:
www.treestuff.com/apta-air-powered-tree-access/
Really cool, I'm looking to see if it's possible, a weapon like the one that appears in the movie Fast and Furious 6, the one that sticks into the wall hahaha it's something like a harpoon
Is 12 oz bag what you like to use zacceus?
@@RC-Heli835 yeah! The 12oz seems to be a nice balance of factors. It not too heavy to get really high, but it still seems to have enough weight to come down once it's over a branch
@@zaccheus Cool! I just ordered enough stuff to climb with a blakes hitch. Have to wait on a climbing device.
Finally got the broke bucket truck out from over my house yesterday.
@RC-Heli835 That's a good place to start!
Did it end up costing a lot?
@@zaccheus No one could cross reference the number on the pump but a place called Force America who specializes in hydraulics matched it up for me for 440 bucks!
Come to find out I had run one tank of gas in an Echo top handle 14 in chainsaw that I had met someone to buy at home depot at day break. When it ran out of gas I went to take the bucket down for gas and it was game over. What had occurred was a check valve bolted right onto the pump had failed and let its check ball go to the very next fitting which was actually screwed into the check valve. A tee that goes to idle up the throttle hydraulically when pressure is made by the pump.
That ball was stuck in the tee with some plastic trash behind it.
When I first found the damaged chk valve I got the spring out then but it took us a while to run down a pump and I forgot to look for the rest of the trash and ball from the check valve.
So you guessed it my new pump immediately failed. The check ball had the system so completely locked down nothing was circulating. Luckily I found a new pump on ebay identical to the new failed one for 160.00 bucks.
So yea all in all I'd say we have a thousand bucks in it and it still needs a starter. The start will start the truck about every 18 trys. Also a solenoid for the backup 12V DC hydraulic motor/pump to make it work again.
Also after the pump started leaking, a failing relay cutting the PTO on and off broke the shift fork on it as well. So had to replace that!
Because of that I bypassed all the electric and make it air only PTO. Too many failure points on electric to leave man stuck in bucket!
@@zaccheus I lucked up and got 12 Kong Carabiners on Fleabay for 75 bucks. 50 Kn Carbin steel!
150 dollar pelican rope locally. Spent 49 bucks for 220 feet of Vevor 1/2 inch rope on amazon. Its so stiff that a blakes hitch doesn't hold at all on it so gonna use it to zip with.
13 buck hand saw from the hardware. And a few other things.
Really 3500 bucks would get a man up in the tree with just the basic Arbor rated gear. You need so much stuff just to get started man.
I got the SOB climbing saddle off amazon for 63 bucks and like it ok just wish it had a shoulder harness. That's a 10th of what a Monkey Beaver 2.0 cost's but it works and seems well made.
My 11 oz throw bag fits the launcher way too loose! It barely shoots to the lowest branches. I figured it up my air chamber has less than half the cubic inches that yours does so gonna have to get a larger air chamber.
What size throw weight fits in the 1 1/2 pvc pipe ?
@grdnsherman I've found that 12oz works pretty good. I think I've been able to fit 14oz in there too, but it kicks back harder
What’s the most psi i can safely fill it with? I made an exact replica
I cannot say, I'm not a plumber or engineer. I don't feel.comfortable putting more than 100 psi in it. But even that much pressure could severely injure you if it broke.
Thanx man I’ll probably just stick with about 60 no more than 70.. thanx a lot
@@RascalThaPoet That seems to do the trick for me 🤷♂️ the faster you pull the handle, the more it helps too

What about an upgraded version that uses 12g co2 carts???? :)
Oh that'd be cool. Might send the thow weight into orbit 😂
@zaccheus ive been working on something similar but from a reverse perspective. Your solution fires the throw line to the target/shore. First my problem) when going out boating alone and coming back in, its a hassle and a race when docking the boat to try and tie off the lines both at the front and back, to prevent the boat from veering its ass outwards, depending on winds and water currents. Solution) what if when you came in with the boat, the lines would fire from.the shore into the boat, and all youd need to do is tienit off

What psi do you pump it up too???
Typically 60-80 psi depending on the tree
Purchased an 11 oz throw weight. It won’t fit in the 1 1/2 inch pvc.
@grdnsherman mmm, I'm sorry to hear that. It must be a really tight weight. Maybe try just sitting it on top of tue barrel and giving the other end of the cannon on the grass. It's something that doesn't push in very well. It kind bunches up if you push on it
Back in the day we made potato cannons and in the early days of utube had a video of us on a job site in a basement shooting a hard hat and canned vegetables with our potato cannon paid for having fun ...

I used 1.5" but if you have different size throwballs, you can just take your throwballs to the store and test fit them in the different sizes.
@@zaccheus ok, thx 👍
Don’t trust the pump gauge
….you loose psi. Check it though
All guages loose psi unless you have one integrated into the system. The thing thay mayyer the most is that it's fairly consistent from one cycle to the next. It's okay if 10 psi escapes, as long as 10 psi escapes every time.
Screw that! I have a 6ft long spud gun i made for a science fair project! 6inx12in combustion chamber, reduced down to a 2inx5ft barrel. And a BBQ igniter for spark. Lol I dont even mess with throwline, i tie my climbline to the bag and send her on her way! Lol im jk. Im not that slow in the head. It would be fun to test it tho! To see if a regular spud gun that uses fuel/spark can out do a similar sized pneumatic spud cannon. I know ive launched potatoes a tad over 300yrds with it. Its a bit temperamental tho, because if you dont get enough oxygen inside the chamber. It wont ignite properly or at all really. But it can be a lot of fun! My science fair project was to find a way to simulate how a combustion engine works. Have you, i think i may have been in 8th grade tops. So it was pretty clever for a 13yr old to do. Basically the potato represents the piston, combustion chamber represents just that. And the screws i had in the sides of the combustion chamber represented spark plugs,, and the ignitor represented an ignition system. Unfortunately, i had to do it via a video. Since school wouldnt allow it on school property. Lol But it was a very fun project. Forgive me for going off topic. Just thought some may be curious what my project was...
Lol, I thought about going that route. It's obviously a little hard to regulate. The pneumatic version here isn't perfect either, but you can atleast work with 10 lb increments
Drain waste and vent pipes are not for pressure
Yes, I believe I specifically mentioned the importance of getting pressure rated pipe and fittings in the video. DWV materials are no bueno.

What if it was just a single pipe? Less to fail and you launch it on the ground like a grenade launcher? Less accurate but less to fail and safer. 🤷♂️ I might try building one.
You could definitely try that. I think the accuracy is a big part of what makes this handy, but I imagine you could get good with it in any form if you practiced. It might be good to increase the pipe size if you just go straight with it. If you don't have very much volume behind the valve, you might have to use a higher pressure to get the same results.
@@zaccheus I just put a dent in my car trying to throw a line up so anything is improvement on that. Apparently I suck at throwing 😂

Might be safter with metal, though it's bad when it explodes too. I'm not sure using an unregulated pressure source will work all that great for throwline stuff though. Sometimes 400ft is 300ft too much 😅

Hahahaaaa, that's a great idea. I probably would have a trouble keeping batteries in it, but it'd be sweet when it worked!

Your up and coming,
But it wasn’t “about it”
Just like a potato cannon
Hmmmm, I'm thinking that increasing the size of the tubing on the air storage tank would make the throw ball go a lot faster and higher 🤔 I won't do the extra 90° and T junction as those would weeken the system...... I'll probably make some handles that can clamp around the tubing...... maybe launch it RPG style and put some sights on it of some sort 🤔🤔🤔 I don't really need one, but just the possibility of such a monster just strokes the "Deadpool" parts of my mind. Don't worry, with the larger air container I won't need to go that high on the pressure, but I might try a bit more once I have confidence that I'm not going to kill myself 😁
Haha thays the beauty of it all. You can make it however you want!
Tree Stuff $260. no time to make or materials to buy.
That's also a viable option. The only think I don't like about the APTA is that the compression chamber is smaller so it requires more pressure and it's just plain heavy.
Tu parle beaucoup trop
