Can someone help me with my fatal flaw in my spudgun design?
So i have built spudguns in the past and with every new gun i make it gets bigger and better. So i just found pressure rated 3" pvc and im going to use it for a new air chamber. Its a simple end around gun with a piloted sprinkler valve so yea the design is good. Except for one thing. I am enthusiastic enough of a spudgunner to use an air compressor to power it when im at home. but when im at a park or some open feild i bring along a bike pump to pump it up. But with each size up for the air chamber it takes longer and longer and longer to pump. Im not enthusiastic enough to buy a compressed air tank for $60. so what should i do to power it up. i dont have enough room at my house for a distance or height shot and it will take forever to use a bike pump so what should i do. PLESE HELP ME i will try to post pics of it soon HELP ME
