Hmmm.... this is why I put it on here for some brainstorming. I will post the final plans for approval. I have an idea for a slow leak system that will do it. I know hydraulics may be easier... but more fun? I think not :wink:

Would you really need a piston valve to actuate the cylinder? You do not necessarily need speed here, just force. That's the thing... if you think about what the force is like for an average man to swing an axe and split a log, you could just imitate it with pneumatics. I don't want something slow ...

What kind of pressure you do you think this will need to run at? I'm basing ...

And what would be the best way to achieve this if i want to be able to split the log? My idea was to have some sort of...

This is my second cannon actually submitted to the site, however it is one of many that I have built. It is a coaxial piston cannon with a 2'' chamber and 1/2'' barrel and seals like a dream using a 1.5'' end cap and a spring. I will soon post pictures of the inside because I machined the barrel sta...
