How to Make a Ball Valve Air Cannon (Under $30)

The tutorial shown in this video is about the PVC cannon video uploaded a while ago. So many people wanted me to make a tutorial, that I decided this would be the first. Here it is.

This was the first video that took longer than 1 hour to edit and upload to Youtube. In fact, it took more than 8 hours total over a period of days. The first day involved getting the shots like the stop motion and videos, the second involved making the first half of the video, and the third day was basically cramming to finish it on the deadline. I hope you Youtubers enjoy this video.

If you are having trouble getting the parts down, please comment on my blog or send me a message. The script is posted on the blog if it is needed.

I only accept requests from subscribers, so if you have an idea, please subscribe. I want to hear your ideas!

I was wondering what I did wrong, I used a standard bike tire valve stem and I epoxy puddied it into the hole in the end cap. But when I fill it (using a standard compressor) it leaks and I'm not sure why and it wont fill above 30psi no matter what I do. It used to fill as high as I wanted. What would you suggest?

[TSRAA]

@shocktoberfest08 Stick the end of the cannon with the bike valve stem in some soapy water after pumping it up. If there are leaks (bubbles flowing out of some areas) then you could try using hot glue around the epoxy putty first. Wait till it's fully dry before pumping because the air will make bubbles in the glue. If there are a lot of leaks, cut off the end with the valve stem and put on a new end cap and valve stem (with lots of epoxy).

If I used very small pipes and tubing, do you think that the design could be created pocket-size?

[TSRAA]

@ncx1234 Maybe, if you can find piping that small with pressure ratings. You'd also have a problem with finding the right pump.

Very good but how much psi do you think it can hold max if it's made exact to the one you made

[TSRAA]

@guesswho357357 Probably 100-120 PSI. Enough to launch a tennis ball 350 yards.

@KingBeast1216 Simply spit upon your ball area and whack it in and out until the epoxy comes out. If you do this fast enough over and over it will work. It certainly solved my stiff ball problem. I would also suggest moistening the nozzle and nipple area too.

I was wondering if i could reduce the 1 1/4" pvc pipe to 3/4" pvc pipe at the barrel end so i could fit airsoft bbs into it without any room for the bbs to move around. Would that cause the 3/4" barrel to have to much psi when im ready to shoot it since i reduced it?

[KingBeast1216]

hey my ball valve is real stiff so how exactly do i open it fast enough?

[cooperDG123]

@53coolrunnings it would work but it might explode cuz u dont how much psi is in it i dont recomend this

[lezamarinesi]

did u use glue???

[hotdogsandlettuce1]

Nice!!!!!!!!!!!!!! :D



[YouAskWeDestroy]

How did you make the animations?:)

[UltimateWorkshop1]

i am going to make this just to have fun and for airsoft, i am going to build it and then make a video of how to make my airsoft shells for it and i will give u cedit for the cannon!!

[shallowstorm211]

y do that when i can buy a bb gun for 27$

hey dude im keen on making something like this but instead use a cricket ball/balls (similar to baseball) to practice my cricket. 4 questions mainly

1) is it possible to make the turret to rotate in the x and y axis (im possibly thinking to move the entire base on the x and y axis using motors)

2) is it possible to have a dispensing device so that you could release many balls in a row.

3) Is it possible to connect it to a continuous air compressor device
