Peacemaker MK2 (Water cannon)

Unread postAuthor: Lokoyo » Tue Apr 07, 2009 2:42 pm

This cannon is pretty plain and simple

Specs:

Firing Valve: 1.5" Ball valve (Firing water)

Chamber:
- (13) 1' 2" Sch40
- (2) 2" 90 degree elbow
- (9) 2" T's
with some other stuff that I didn't measure :P

Barrels:
- 4' 1.5" PVC
- 4' 2" PVC w/ transition from 1.5" to 2" and nozzle from 2" to 1.5" at muzzle

C:B - Approx. 3:1 to 4:1


Firing water:
45 ft+ effectiveness (Stayed pretty straight/on target)

Recoil:
The cannon would slide back 2-3 feet
(I can't carry the cannon by myself because I have to hold the barrel up in order to keep the water in and it's sorta heavy + im scared of holding)

Reason for all the T's and vertical pieces:
Gives support from the recoil caused when firing water (Over-under designs are destroyed when shooting water)

looks like a lot of fun :D
I would add some kind of lever to the valve handle for easier/faster opening.

I was thinking about that but I was scared because if I make a handle, then it might take me longer because its a farther distance, thus the recoil will be in play and I could hurt my wrist/hand.

With this cannon, I rarely am able to fully open the valve. Sometimes Im even scared of firing :P I already cut my finger somehow because of the recoil

You say scared, but thats actually just wisdom. Dont overhaste and do stupid things, recoil can do terrible things.

Your barrel/reservoir looks like it has DWV reducers.
You should replace those, and then experiment with smaller nozzles. A larger reservoir is also an option.

Overall: Nice water gun!

I would mount a handle on the ball valve such that as the cannon begins to recoil, your hand would tend to open the valve further.

as to the cuts, wear gloves :wink:

How big was the cannon? I can't imagine this cannon breaking bones. Injuried for a few minutes/hours maybe but not breaking bones O.o
