- In this video I show detailed instructions on how to build an air cannon that can shoot a throw line up into a tree which can then be uses to attach a pull rope. This is essential if you need to attach a rope and pull tree that you are cutting.

Hi Dick. I have been looking for a method to build one of these for a bit now and have probably seen most of them on youtube. I must say your video was the most well made. You were informative and left no questions unanswered. I am now headed to Lowes. Thank you so very much.
@@jcalexander552 thanks for watching! Enjoy your air cannon.
That's a work of engineering art...thanks for pointing me over this way! When I was younger and stupider, I built something like this to shoot potatoes, powered by hairspray. It was a beast and I'm surprised I never had an explosion or some other disaster. I'm in the Ozarks woods now, and have several large trees that are dying and leaning over my power line and garage...bought the Masdan rope puller and some snatch blocks and some cable...waiting for winter due to ticks and chiggers....
Thank you!
Well now I see a winter project in my future. Thanks for a step by step tutorial.
Thanks for watching Tony. It sure beats trying to throw a bag by hand!
One of the best tutorials I’ve seen - that’s high praise, indeed 👍🏻
Thanks for watching and thanks for the kind words Mark! It’s greatly appreciated.
Hello. I just built one using most of your design tips, particularly about the 1" valve and the 1.5" pipe. I just shot a 12 oz bag up 93 feet at 80 PSI. Works great. Thanks again!
So glad you like it. Thanks!
Thank for explaining and showing this build. You're the second man I found online using a sprinkler valve. That looks much better than even the butterfly valve I have in mine.
Thank you also for the other comment replies where you detailed your experience with different brands. I will try to find a Rainbird. And I'll see if I can use the idea someone else posted about a safety component.
Thanks Paul. On my first build I used a butterfly valve. The sprinkler valve is MUCH better!
what a great instructional video. step by step was great. i might just have to make one for myself and i have a couple trees i'm gonna need to rope up to fell in the right direction. thanks for doing this.
You found the video! Thanks.
Just completed this build today and it works great!!. Got to work on my aiming some but the cannon gets my throw ball right where it needs to go. Thank you for taking time to show this. You also have me cutting firewood now.
Hi Jody. Glad it’s working well for you!
Great video Dick, your instructions were right on!! Anyone wanting to build an air cannon should have no problem.
Thanks for watching Terry and thanks for the comments. I’ve really enjoyed watching your firewood shed build!
Very nice build, oh, and love your dog!
Thanks for the tutorial!! Will build one after the weather this weekend. Stay Hydrated and Have a Safe Day
Thanks for watching David. If you build one I would recommend going with a Rainbird brand valve like I have on my original cannon. The Orbit certainly works, but I think the Rainbird valve will shoot a bit farther with less pressure.
Thx for sharing your expertise Dick. Interesting build however it wasn’t overly complicated once you showed what parts were required for the device. Looks like it functions extremely well and with great accuracy.
Thx again. Mark from Niagara
Thanks for watching Mark. It sure beats trying to throw the bag up by hand!
Clear, detailed instructions. Well done.
Thank you and thanks for watching and commenting!
Hey Dick! This was a great sit down instructional video, well detailed and informative! I’ll definitely be looking into making a version of this sometime! Thanks! Andrew from NB :)
Thanks Andrew. It sure beats throwing it up by hand!
Thanks for a nice detailed video. After several hand throw attempts (actually using a fishing pole, which got tangled each and every time!) I gave up and looked for better ways and found your video. I really like the trigger you built and will use the preferred 'Rainbird' 1" brand. I believe the trigger is superior to a 1/4 turn valve. I'm going to start getting parts right away and begin building. After a bit of thinking, I was curious IF I went with a larger diameter 'Air Chamber' tube if I might achieve higher throws with the same air pressure.?.? I created a parts list below from your video for quick viewing.
1 1/2" sch 40 PVC pipe - 38" (Barrel)
1 1/2" sch 40 PVC pipe - 26" (Air Chamber)
1 - 1 1/2" PVC Cap (end of Air Chamber)
2 - 1 1/2" PVC inline coupler
2 - 1 1/2" PVC reducer to 1" NPT female
2 - 1" to 1" NPT steel pipe nipple
1 - 1/4" Brass nipple (1/4" to 1/4" NPT male)
1 - 1-160 psi gauge (Merlin 64554 - 1/8" NPT on back) or equiv.
1 - Slime #20128 TR 416 Schrader valve or equiv.
1 - Lever Style Blow Gun (Central Pneumatics #68263) Harbor Freight or equiv.
Thanks for the detailed comment David! I’m not sure if the larger chamber would give you more height. A larger volume of air would probably help. I’ve shot mine around 80’ up which is more than I need.
Dick, you should go into production!! Awesome teaching tool here also 👍 Quality materials, quality video ….Brittany needs one in pink please,😏 Looks like you were well supervised during this production 🐾🐾🐾🐾. Thanks for taking the time to show us how to make one 👍👏 Rick
Thanks Rick! You’re right, my buddy Clifford was watching over me the whole time haha.
Great tutorial . Awesome build . You should have been a shop teacher . Thanks for sharing !!! Del
Thanks Del! It sure beats trying to throw a line up by hand. Thanks for watching… I really appreciate it. - Dick
This is by far the best cannon I've seen made! Definitely the blueprint I'm using for mine, thank you for the awesome content
Thank you Larry!
@oldguyfirewood happy to say I built mine last night! I'm having trouble with it transferring the pressure through the valve into the barrel, if you have any tips!
@@larryenticeher I don’t know unless some of the passages in the valve got some epoxy or jb weld in them by mistake. I found my original gun made with a Rainbird valve functioned a little better than the Orbitz valve. It might be worth a $20 investment to try a Rainbird valve.
Thanks I been needing one of these. Thank for showing how to make one
Thanks for watching Tommy. This was the second one I built. The one change I’d recommend is using a Rainbird valve instead of the orbits brand. That’s what I used on my first build, and I think it releases better.
Great build. Great work!
Thanks my friend!
Thanks for demonstrating this build. Genius! I’ll be building one in the near future. Thanks again!
Thanks so much for watching Rick. It sure beats throwing by hand!
Thanks for the info Dick.. Will definitely be a fun build for a few of us this winter.
Thanks for watching Daniel It’s a fun toy… I mean tool ha!
Dick, great explanation. 👍🏻🇺🇸👏🏻. Larry in Reidsville
Thanks for watching Larry. I’m north of Durham… not too far away. It looks like we will get some much needed rain this weekend here in NC.
Brilliant video!!
Thanks Dan!
Just built one per your instructions great easy build works awesome
Great news Jan. Thanks for watching!
I like your valve trick! I used a brass butterfly valve. Your irrigation valve looks like it’s more readily available and requires physical disturbance to fire.
Thanks for watching. I originally used a bras butterfly valve on my first build, but it didn't;t release as fast as the sprinkler valve, and it tended to make me move the gun off target
Excellent!!
hThanks for watching. It sure beats trying to throw a bag up!
Hey Dick, I built my own cannon thanks to you, but the throw bag I got on Amazon is too big to go into the 1 1/2 PVC...what brand is yours? Added later: I decided to try an experiment and save some money. I heated up a soldering iron and melted a hole in the bottom of my throw back, and the inner bag that holds the lead shot. Took out about a third of the shot, then sealed it all back up with polyurethane construction adhesive (that stuff is really tough). Waiting for it to dry to do test fire...will let you know if I scatter shot all over the woods....
Let me know!
Have you done any experiment action with barrel length? First one a friend made was overall about 8 or 10 feet long. Way too long and held too much air. We ended up making two out of it! Later another friend made an even shorter one. I use mine to shoot a 3/4 pvc slug ( two 3/4 end caps back to back) over a tree to pull up amateur radio antennas.
Thanks for watching. I haven’t tried different barrel lengths. This is the second one I built and I figure “if it’s not broke don’t fix it” lol.
I have got to make one of these! 😮😂 Nice job and thank you.
Thanks for watching! I would recommend the railbird valve which is the valve I used on my first build. I think it releases the air a bit quicker.
I agree with all the other comments...great information!! See you at the PB show. obie from ohio
Thanks Obie! Looking forward to PB… hope to meet you there.
for the projectile i am using, (16oz. throwbag) 2"pvc seems to be a better fit than 1.5". Do you think the same lengths for the barrel and air chamber as you used for 1.5" will be ok or should I use different dimensions? Thanks again, Dick.
I’m not sure. I think the barrel length would be ok but you might need to go booger on the air chamber.
@@oldguyfirewood Thanks again. will do. I figure I can always go up a size or turn 2 90 degree ells if the air chamber gets too long
New sub! Never thought of the sprinkler valve. Built one years ago where I used to work. We had an air starter valve just taking up space and fairly expensive. It worked great! Now I want one for just what you are using it for now. Thanks for the clear instructions.
Hello Lloyd. Thanks for watching and subscribing. It sure beats throwing that bag up! I hope you watch all my available videos. I use the air cannon in all my videos where I’m cutting down large trees.

Great build! What brand throw ball and weight was used in video?
12 oz. don't remember the brand
Very cool. Thank you.
Glad you enjoyed it! It sure beats throwing by hand.
Great tutorial Dick. It looks like it works great. Do you store your throw line in a bucket so it doesn't get tangled when you launch it or lay loose on the ground?
Hi Brittany and Francis. Thanks for watching. I have a throw line cube that I store the line in. It will sometimes tangle if I shoot it out of the cube. I’ve found it best to lay it loose on the ground. The only problem is I get my feet all tangled up in it as I walk around ha!
Old Guy Firewood -> Interesting! A question, if I may. Why use JB Weld (or any sealer)? Why not a threaded plug?
Thanks for watching and thanks for the comments. The passages that need to be plugged are irregular shaped and it seems easier to use a sealer that can be forced into the openings.
nice vid, I added a 125 psi pressure relief valve in case someone gets a little rambunctious. I actually added a scatter shield to a larger higher pressure gun.
The classic term is a potato cannon and I find sweet potatoes go a LOT farther.
Thanks for watching! The pressure relief valve is a great idea, especially if several people will be using it.
Hello Dick we are in Shelby North Carolina visiting our oldest son, are you anywhere close to There? 👍🏼🇺🇸
Hi Larry. No I’m about 3 hours east of there. Are you going to Paul Bunyan? I’ll be there Friday and Saturday. Hoping you and Robin might be going.
@@oldguyfirewood yes we are planning on going to the Paul Bunyan show, See ya there🚜🪵👍🏼🇺🇸
For the trigger mechanism instead of using plastic could a metal t joint work?
I’m not sure if that would work. I’ve only built them as shown in the video. Thanks for watching!
Hello Dick..... My sprinkler valve is 24v AC. Did you just cut the wires and use the bleeder with the blow nozzle, to release the pressure??? Thank you.
I removed the solenoid with the wires and plugged that hole. I show the details in the build video. Thanks!
Nice one . Who is the boss looking in .
Clifford the woodyard dog is in control!
Great video I can't wait to build one. However, I can't help but wonder what keeps the air from flowing through the blow gun/trigger assembly and out of the nozzle, is the other end plugged?
Thanks for watching Harry. The diaphragm in the valve is held shut by the air pressure in the gun. When you pull the trigger air rushes in the nozzle and releases the diaphragm.
@@oldguyfirewood Thank you for clearing that up. makes sense. Guess i was overthinking it too much lol.
I wondered the same thing. I don't know that I fully understand it yet without it in front of me, but I get the idea, I think....
Perhaps you could explain that again or make a simple video to answer it a bit better? Thanks in advance.@@oldguyfirewood
Great video! One thing I’m changing is to add a 90 to the blowgun instead of a straight nipple. This will allow it to lay flat against the cannon.
That’s a great idea. I’d also recommend using a Rainbird valve instead of the Orbits. They seem to release better.
What's to keep the air from rushing out of the other end of the trigger nozzle when you squeeze the trigger?
Thanks for watching! The design actually creates a vacuum inside the valve. When you pull the trigger air actually rushes IN the other end of the nozzle.
The thing that you call a reducer on the barrel end. Isn't that called an increaser?
Hi Maynard. I guess it depends on which way you’re looking at it! Thanks for watching.
A 3/4" plug fit perfectly where you removed the solenoid.
I have all the parts and am ready to put it all together. Thanks for the tutorial!
Thanks for watching!
Awesome build! How much did all the materials cost?
Thanks Matt. It was right at $60. The only change I would make is to go with a Rainbird valve instead off the Orbitz. My original has the Rainbird and I think it functions better.
@oldguyfirewood thanks for the quick response. First time I watched the video I skipped around and now I'm realizing that you state it's $60 at around 2:30...thanks again! I can't wait to build this and use it for my tree service business!
That was awesome
Thanks for your support John. It sure beats throwing by hand!
Can anyone please explain how the trigger mechanism is actually working?
The valve is held closed by the air pressure in the air cannon. Pulling the trigger somehow equalizes the pressure on the diaphragm and the air is allowed to flow through the valve. That’s a high level explanation but it may help some.
Great build but definitely over build. I made mine for about $30. 4in chamber down to 2in barrel, simple ball value, tire value, i did use duct tape to reinforce everything. I haven't needed to go over 90 psi. Been working great for almost 3years. I use a tire inflated machine that has pressure gauge on it.
Thanks for watching and commenting. It sounds like you built a nice functional unit. I had a ball valve on the first one I built but added the trigger mechanism to make a fast release easier. Like you, I’ve never put over 90 lbs in it… usually between 60 and 80.
Great
Thanks for watching!
OGF, I found it, and You can bet a buck this is gonna happen, I book marked this one so I can find it later!! now to buy a laptop so I can take this info with me to the shed and build it.
Sounds good Ben! I would recommend getting the Rainbird brand valve over the Orbit. I think it releases better (it's the valve I have on my original air cannon). Thanks for watching!
What weight is the throw bag? they make those things from 9-16oz etc....
thanks
Thanks for watching. It’s a 12oz bag. If I was to build another I would probably go with a larger sprinkler valve.
@@oldguyfirewood Put a 3 inch pipe for an air chamber I think the valve is probably fine..Thank You!
@@oldguyfirewood do they make one bigger than 1” ? Thanks!
@@rksg2003 not sure what your question is. Are you referring to the throw bag?
@@oldguyfirewood do they make a bigger valve than the 1” inch you used?
👍👍
Thanks for watching Bill!
Just finished building one per your instructions but the blow gun only releases air slowly - not explosive enough to launch my string. Any suggestions?
Hey Gary. I’ve had two other viewers build the gun and they worked great. Are you sure you plugged the holes in the valve correctly? That’s the only thing I could think of unless the valve itself or the blow gun is defective.
Instead of that airgun you are using to trigger the valve, I used a Kobalt Pocket Blow Gun from Lowes ($8), with a 1/8-NPT mini 90* ball valve from Amazon (2 for $10) on the end of it for a safety "switch" so if you accidentally bump your trigger, it won't set off the cannon before you're ready to make the shot. Once aimed, open the "safety" ball valve, and pull the "trigger" NOTE: The pocket blow gun does not have female NPT threads on either end, it has standard straight threads in its plastic body, but it screws onto NPT fittings and seals just fine with teflon tape, since the thread pitch and diameter is close to the same as NPT threads. So it fits onto a male 1/4" NPT nipple fitting, and the 1/8" NPT mini ball valve screws right into the end of the pocket blow gun.

Somehow I missed your comment earlier. I really like your idea for the safety valve. Once loaded it should be treated just like a firearm. An accidental discharge could seriously injure someone. Thanks for watching.
@@oldguyfirewood
It really does give some piece of mind, and helps prevent an accidental discharge from occurring.
