i like the erganomik desing . you should get a backpack or somthing to put a tank in (5 gallon works well for that) and get a cartrige. i want to no wat the range accuracy and power of it is so post the results

Thank you, its been a fun build, and my future ones will only get better, more power, more accuracy, more realistic

Why thank you "Dude" the power is untested but I expect it to be exceptional. the accuracy will be questionable with a smoothbore and marbles

A 20 litre tank in a backpack...hmm okay :roll: what the f*ck

The cannon needs a new piston, so I can assume since the valve is not working, neither is the cannon for the time-being.


Edit: Forgot to comment on the nice build ;)

Definetly a nice cannon you have here. Like dudeman, I too will be waiting upon the performance results. You did a good job mounting the stock to the PVC as well. :)

Ha thats what I was thinking.

I found this on mcmaster, does anyone have any objections to whether or not this would work well as a piston

Might be some friction it being neoprene and all. I'm not sure how well lubricant would lube it up. It could work but I wouldn't know for sure.

Is it large enough diameter for 1 1/2" PVC?


Check my edit in the post above btw ;)

very nice build, great looking cannon you have there.

one question though, how did you attach the stock?
is it just jb welded on there?
can't quite tell from the pictures.

otherwise, great cannon. hope you get the piston working so we can see it
in action :)

thanks Crowley,
I thought about that too, so I might get some solid stock abs plastic for a piston, and machine some O-ring grooves perhaps then just mount a rubber face.

Oh it can be done, it's just about as practical as a DVD rewinder.
