Like Master Yoda speaking Inuit....

Wish we had ...like....spellcheck...or somethin' :roll:

I only got guestimates for you.
I think it's about 3 liter and it takes about 5 to 8 minutes...

All in all, I think it's not bad, considering the powerful shots I get in return.

I fill it (deja vue) with a fridge compressor.I plug it in and fill it.
As in...in one go..

:roll: ? :D
You probably think I use a regular compressor to do the bulk first, but no..I don't even have a regular one anymore.
Who needs 'em..?


what coupling are you using with these high pressures.

Questionmark, I presume..

I use regular Quick Disconnects.
They are rated for 40 bar.
The problem ( more of an issue, than an actual problem) is, you can't manually disconnect them under that amount of pressure.Even if you could, you'd wreck them in no time.

So, I use a bleedvalve to take the pressure off before I disconnect.
Lessens wear on the O-ring as well.
Even at 100 psi ( 7 bar) I recommend doing this for the same reason.
I've worn out my share of QD's before I adopted this method.

Double post, but news, and no need to start another topic:

I've shot it in front of 100 people at a carnaval-parade!!!! :D

Strange to walk the streets with a very overpowered spudgun and not having to fear arrest.
Some went WOOW when they saw it, others acted like it was normal, but no negative response.

I strapped it to a bench, stuffed the barrel completely full of confetti, and fired at 12 bar.I had to tell a lady to move over, she barely stepped aside :? .So I went for it.
Cha-Woooooshhhhh.
A cloud of confetti, about 15 meters up and 10 meters wide rained down slowly onto the crowd.They all went: " Aaaaahhhhhhh"

I have to say, I liked it better than shooting Redbull-cans at work! :P

Actually, I did a test before that, with all neighbours watching, at 5 bar, but the main event made my day!!

I hope I can get a vid.I didn;t shoot one myself, as I had a job to do.

Cool! Did you get a special permission from the carnival brass/security people to use it there?

Wow when are you doing that again? BTW what's up with maggotman's dislay picture? Maybe somebody should ban him, he gets annoying with his ''inability to click the spellcheck button''.

You can tell how awesome a cannon is by the pressure used.

I wouldn't.

A 2 inch porting piston valve for a 1/2" barrel???


Talk about massive choke!

I don;t get how an aa battery would be more impressive than a redbull can full of concrete, for example.

Like trying to crossbreed a great white with a pirana, cause piranas are cool....

Anyway, considering your postcount, you'll probably have to learn about this stuff.


I did not get permission, and with Mr.Porter all charged up, I don't need permission neither! :D

@ Stickytape: If you have a problem with anoter member, PM PCGUY about it.I can't help you.
I ridiculed maggots way of writing, and he seemed to better himself.
Humour is preffered to banning, IMO.

New vid..shot at work...in more ways then one..

I am unable to edit this vid without losing the audio...
Pressure used was only 12 bar..I did manage to damage the wall behind the target..a redbull can leaves quite an imprint..try and spot it in the vid.



This vid was shot sometime October..
