Harvests of a cheap water gun

Post by mysterio » Sun Aug 29, 2010 4:47 am

Well, i went to the 99 cents store to go and get a water gun to take apart. After dissecting it, I found all the thing you would expect in a water gun, (2 check valves, trigger, flexible pipe). After tinkering with an especially think section connecting the trigger and check valves, I found a seam, and pulled it apart. inside, i found a piston cup, and a waterproof spring. the spring is really strong, and the piston cup matches up to about 1/2 inch in diameter! They most likely vary with different types of water guns, but I'm sure that some of them are exact.

I'll post pics if i can.

I'm gonna try and get a different kind this time, a stream machine one. this one should have a larger piston

Edit: wow. the piston from the stream machine gun had an exact 3/4 inch seal, with a 6/16 inch ID. its like a double piston cup, but all one piece. you could put it on a threaded rod with washers and nuts and make a pretty efficient pump with it. ill put up a pic of it and the other one sometime soon.

all this from the 99 cent store.

I've found some simular things at Dollar Tree.

Also, you're sort of double posting. You should make edits.
