Clear, detailed instructions. Well done.

Very nice build, oh, and love your dog!

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....

One of the best tutorials I’ve seen - that’s high praise, indeed 👍🏻

Great video Dick, your instructions were right on!! Anyone wanting to build an air cannon should have no problem.

Well now I see a winter project in my future. Thanks for a step by step tutorial.

Thanks for the tutorial!! Will build one after the weather this weekend. Stay Hydrated and Have a Safe Day

Thanks for demonstrating this build. Genius! I’ll be building one in the near future. Thanks again!

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.

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 :)

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.

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

Great tutorial . Awesome build . You should have been a shop teacher . Thanks for sharing !!! Del

Thanks for the info Dick.. Will definitely be a fun build for a few of us this winter.

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.

Thanks I been needing one of these. Thank for showing how to make one

Great build. Great work!

Just built one per your instructions great easy build works awesome

Brilliant video!!

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

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

Very cool. Thank you.

I agree with all the other comments...great information!! See you at the PB show. obie from ohio

Dick, great explanation. 👍🏻🇺🇸👏🏻. Larry in Reidsville

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.

I have got to make one of these! 😮😂 Nice job and thank you.

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?

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.

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.

That was awesome

Old Guy Firewood -> Interesting! A question, if I may. Why use JB Weld (or any sealer)? Why not a threaded plug?

👍👍

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....

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.

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?

A 3/4" plug fit perfectly where you removed the solenoid.

Great build! What brand throw ball and weight was used in video?

Great

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.

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.

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.

What's to keep the air from rushing out of the other end of the trigger nozzle when you squeeze the trigger?

Can anyone please explain how the trigger mechanism is actually working?

Hello Dick we are in Shelby North Carolina visiting our oldest son, are you anywhere close to There? 👍🏼🇺🇸

Nice one . Who is the boss looking in .

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. www.lowes.com/pd/Kobalt-Pocket-Blow-Gun-with-Safety-Nozzle/1000404937 www.amazon.com/dp/B09D91R8TD?psc=1&ref=ppx_yo2ov_dt_b_product_details

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.

The thing that you call a reducer on the barrel end. Isn't that called an increaser?

What weight is the throw bag? they make those things from 9-16oz etc.... thanks

Awesome build! How much did all the materials cost?

Just finished building one per your instructions but the blow gun only releases air slowly - not explosive enough to launch my string. Any suggestions?
