I certainly wouldn't trust PVC pipe to stand up to that kind of abuse for long. You'd be holding a potato cannon that one day would decide to be a fragmentation grenade...
OCC made a 25mm copper pipe version, charged it from a compressor, could fire like a spud gun or alternatively a broom handle.
Considering the quality of the bikes they make, they made a complete Bo$$%Łks of the capillary soldering and bodged up the joints with some kind of
epoxy.
Worked well, fired a spud slug right through a cheapo internal door,
i've looked into this previously.
You don't want to use PVC, it shatters sending spliters all over the place. It also is affected by exposure to UV light making it weaker. You
want to use a different type of plastic that for the life of me i can't remember. That ruptures - making it far safer.
The 'better' safety is to use cardboard - it disintegrates into little fibres.
Wish i could remember the plastic now ....... arrgghh
OMG!!!!
Pwned big time
me and my palls built on about ten years ago we use to fire tennis balls and potatos we usad easy start but if u squrted too much in it wouldnt work there was a bit of a nach to doing it but when u get it right its awsome
We used to fire a water powered bottle rocket from a pipe using the compressor at my mate's yard and we could land a 2ltr bottle on the factory roof across the road about 300 yards away.
i have made one from drainage pipe with a screw on inspection cap. great fun but the only problem is the cap with after a bit of use blew to bits!! i
have a empty fire extinguisher ready to make a new one but aint had the time.
a word of warning though these aint toys and can be very dangerous as the apprentice in my old work thought it would be funny to shot it at the other
apprentice!! it hit him on his upper leg, only 6" from his groin!! he took it like a man but ended up with a blood bruise as bigger than his open
hand!!
you will be really supprised by the power of a spud!
great fun on a summers nite after a BBQ though.

When I was a lad we used to use electrical conduit hammered flat at one end, a banger and a ball bearing. It would pass clean through an old galvanized water tank and then dissappear into the distance. Happy days!
remember you could end up doing time in jail its a wepon.
