Well it seems I am going about things backwards, starting with a big pneumatic and giant hybrid and now going to a small pnuematic. I had left over 4" from the big air cannon and decided I wanted a more portable unit so I built this with a 2" 200psi sprinkler valve. It is in its most rudimentary arrangement, the trigger and fill valves will be relocated as well as the barrel mounted more appropriately, although all of the sch 80 is assembled in its final arrangement. It does work quite well, it's testing has enlightened me to that which I probably should have known already. That being that potatoes expelled from tubular objects at any pressure can result in their fragmentation and dispersal on surfaces and there for such experimentation should be conducted outdoors and not in the kitchen. Luckily the potatoe was quite dry so cleanup was not difficult.

The wife must be delighted nice little cannon, we all need a bit of sprinkler fun in our lives

Well right now it is the parents, which I am very grateful for as as long as I dont perminantly damage the house or myself I am pretty well free to build and test whatever I come up with. I am actually only 19, I suspect that may not have been evident considering the scale of my other projects.

You certainly build and publish older than you are, take that as a compliment.

Compliments taken. Thanks! Yeah, I have always been interested in building things and therefore tended(and still do) hang out with adults mores so than people my age, so that is probably why.
