The reason I get so excited over range is because the piston cannon was able to get consistent 70 foot puddle ranges anywhere from 105 psi+ max pressure without any lamination. Even if 80 feet is over-the-top right now doesn't mean its not possible with 120+ psi, lamination, and constant pressure given the right design.
I still want to keep this thread going for simple ideas.
Do you think it would be a good idea to rename the project and put it in a new thread geared toward experienced builders?
(NOTE: The CAPH successor 'complex design' was not meant to be for beginners)
About your diagram, did SSCBen get a 73 ft range on the riot blast or the 1/2'' nozzle? On his Supercannon II thread (which is what got me into building water guns), he says 73 feet range @ 100 psi, but lists only the output of the 1/2'' nozzle at 100 psi. The riot blast output is measured only at 60 psi, which leads me to believe the 73 ft range was done on the 135X 1/2'' nozzle and not the 500X riot blast. If that is true, then it fits directly above the SuperCAP while having only 1.6 times the flow rate of the 2'' Cannon (albeit for longer that 0.58 sec) and it would be reasonable for the 2'' piston cannon to shoot 70 feet at 150 psi.

watercrazy007 wrote:The range depends on the pressure set by the regular and the pressure lamination is intended for. As far as I can tell (correct me if I'm wrong), lamination has never been attempted at constant pressures above 100 psi, so it is unknown how far this water gun can shoot.
