I know this is old but PC Guy this came up on the Random Cannon side image and I had a quick question.

I see that Joel both fills the twin Chambers and checks the PSI all from the handle. Is that accurate?

That would save me money having to put a PSI on each gun, i can just go with a setup like the above.

When you get a chance..

Nice cannon.

Am,
That cannon inspired me too!
I think the Mega design is good for any size cannon except I would change the design so when you are practicing Redneck Roulette and shooting straight up in the air....the force from the cannon is straight down into the ground as you see with my cannon. It's good straight up and down but not so good at a 45º. I would change the design with 45º chambers.

I liked Joel's video of a water bottle going sideways thru plywood with virtually no argument from the plywood.
I'm sure there is a jumper line somewhere on his cannon that makes the two chambers common.
I use two pressure gages on my WaterDawg™...just to make sure as I normally fill from a 2500 psi nitrogen tank.

Then..... there was the flour episode at Spudtech:

Memorial Day is fast approaching.....I need to shine things up.
Here my gun toting family elected not even to go shooting as is family custom instead...we drank beer and landscaped my backyard. Watch the plywood argue with the projectile on this video:

I was also inspired by the mega launcher, and by your waterdawg.

when I built the swat, I wanted the biggest gun out there, so I used 10 feet of 6 inch air chamber, and a 18 foot 4 inch barrel, along with the now 27 foot long 2 inch diameter barrel.
seen here...

the tip of that barrel is at least 10-12 feet off the ground. (the picture below)

The big cannons never get old.

I kind of had to start from scratch when I moved out of my parents 2 years ago into my apartment, but while I was living there, I couldn't really build/fire anything because I'd totally spook my neighbors. So I had to patiently wait until I got my own house...

Fast forward to February, when I finally have my own place to live and my own garage... I already got myself a nice little drill press, but I'm saving up for a lathe and miter saw.

Once that happens and I save a bit of $ for parts... Well, my garage is ~21 feet long. That's about how large my big gun will be. And all I can say is good thing I have a trailer hitch on my truck! lol
