Thanks, It's a lot of fun especially when you load it with silicone filled tennis balls. We can launch one over 200 yards at 10bar pressure set. The valve has a self pilot circuit, it needs a 2 to 4 bar input for a second to close the valve then you can fill at full pressure. It uses a 24 volt magne...

The shop is quite busy at the moment so might be a couple weeks before we can justify the time. I will keep you all info...

Yea it's the first air canon build. But it was built in an engineering test lab for a large manufacturing company that design's and builds sophisticated train brake systems. so we had access to a full machine shop with some talented machinists, and cost was not a factor. We put this together rather ...

The valve is a high flow gate valve rather expensive, The traverse is a simple center swivel mechanism machined from aluminum with a Delran bushing the ends ride on caster wheels to keep it from tipping sideways, its manually operated (for now), The elevation is made from parts of a train door opera...

Hi want to introduce myself and thank you for havin me here on Supdfiles. I recently built my first pneumatic canon for the National bring your Kid to work day. It shoots tennis balls. The canon is all schedule 80 PVC, the reservoir is 6" x 34" and the barrel is 2.5" x 40". We charged up to 150psi a...

Has anyone done rifling in. 2.5" PVC barrel and if so is thre shone that would rifle a barrel to an air canon. Thanks
