I assume Moonbogg meant 90 psi, which is roughly 4 bar.

Yes, it means you shouldn't pressurize it.

Always use pipe that has a pressure rating printed on it. Schedule 40 by itself means nothing, it only designates how thick the wall is.

I havent tested it yet, it doesnt work inside, but I'll post it when I did. Do you use fluorescent lighting in your house? I have an F1 Chrony that only works indoors under incandescent lighting. IIRC, fluorescent lights flicker and the Chrony needs a steady source of light in order to function pro...

Palmer's Stabilizer. Its a paintball regulator and its not cheap, but its the best out there. Fully adjustable 0-700 psi.

Any videos of this with the barrels spinning?

By the way, nice foot, and welcome to Spudfiles.

Impressive to say the least. Definitely not what I was expecting opening a thread titled "New Cannon"... I'd suggest you change the title so this thread doesn't get lost among the countless threads with similar titles. What made you chose hex screws instead of making the parts threaded? I like them ...

Looks like you missed this topic.

PCGuy just posted saying he's having some email server issues.

I have the tubing rp181 linked to and its a great fit. So tight that pellets have trouble fitting and bb's take a while to roll down. I'd suggested getting something to sleeve the tubing in, because the walls are thin and the barrel will be bent by the recoil. I'm still looking for something suitabl...

It sounds like you've got everything covered, but a picture of one of your completed guns would be nice, just to make sure. I'd feel comfortable using PVC, but some might suggest using all metal pipes and fittings. Does your gun have any type of barrel support? When firing heavier projectiles (such ...

I agree with the others. Just make sure you have a decent light near or above it. I've tested airsoft guns in my basement all the time.

That looks awesome. Was it all done on a drill press like the previous prototypes?

I can't wait to see that magazine in line with the barrel.

Take a look at JSR's coin launcher.

Edit: Jook read my mind!

Excellent test. Do you have a AC clamp on Ammeter? The power draw would be good to know. Also pay attention if the motor current goes up enough and the start relay picks up again. If you miss this and it runs with the start relay engaged due to high run current, it can quickly burn out the motor. W...

Interesting discussion guys but since I have both an A/C compressor and a dehumidifier compressor (practically the same as one out of a refrigerator). I can do some timed tests of filling the same volume to a certain pressure. I could also test how high they can pump in a certain amount of time. I h...

There's a link there where I got my A/C compressor for $20, free shipping. Brand ne.

Excellent first gun!

I'd love to see some pictures of that door. Oh and you'll be fine with a golfball barrel on this, but I'd recommend sleeving it in Sch 80 pipe for extra strength.
