Ahh, this is nice, all the old UKSGC regulars are still about. Gonna get the welding cylinders full from the gas suppliers and then just get it refilled, im not gonna sit there and pump it up myself. I was thinking regarding jellybabies, you know those electric fly swats that zap the flys? They give...

Hi Everyone, Thanks for the response, that reg looks perfect. We have however done some maths and worked out that the paintball cylinder would only fill the gun to pressure a few times. Im now looking at welding cylinders with a 10bar regulator on it, which is the cheaper option anyway... Il let you...

Using a paintball bottle for charging pneumatic canons..

Hi Everyone, Been away from the spudgun scene for a while, I used to own UKSGC, a small forum for the UK spudgunners. Unfortunately had to let it go, as very low users, and no one wanted to put in to help keep the site going. Anyway , the other day I decided to resurrect my big tennis ball gun. I al...

Hi, Yeah I was thinking about water. I was thinking it would be interesting to shoot an old fish tank. I suspect that most of the glass panels would shatter from the pressure rise as the ball breaks the first panel and enters the water. As far as frame size goes, we will have to tinker on the day. D...

Yeah we were going to do this months ago, but unfortunately the guy who had the camera lost the insurance he needed to take the camera out on personal, non paying jobs. Also the camera we were using before (Phantom HD) is not fast enough to catch the ball, and these more capable cameras have only ju...

I just had a look at the cannon, which has been in my garden for about a year. I covered it all up to keep it dry, and luckily, its fine. It all works, the valve was a bit sticky but I pulled it out, cleaned it and re greased it, shoved it back in and its all working perfectly. It all seals fine, an...

On my big cannon, I found that superglue and epoxy didn't really work. My sealing face is made of 5mm thick hard black rubber, originaly used to push poo out from drain pipes. I scored the surface of the piston face and the rubber first. I used an adhesive called 'Sticks like sh*t'. It is a real glu...

Hmm, yeah could be good, but a coke can wont fit in the barrel... Also I am wary about shooting heavy objects, as I think the recoil could damage the valve and the guns structure.... You have just reminded me that i need to go and pick up that aluminium angle that I used to keep the barrel striaght....

It is a Phantom v710. Brand new, saw it up close today for the first time. Its about a week old. Fastest camera ever, 1.4 million FPS max. Hopefully we will be able to get this camera for the shoot, he seemed unsure about availability in Europe. If not, we will be using the Phantom v640. They have a...

Hello again,

After afew months of nothing, I took the piston out and re-greased it and cleaned it up. Turns out that a highly greased piston increases power by a good margin.

Heres a recent video:

Video.

Note how the backstop flew backwards. If the MDF board was supported better, im pretty sure the bottle would have compleatly cleared the board.
