ok so i am making a cannon for the contest and i need to know what the best sabot is to hold water and not leak through in a 1" barrel.....i need something that absolutely doesnt leak through any ideas??

3/4" SCH 40 pipe with a little sanding will fit in 1" pipe then make a bottom out of a plastic material and glue it on.

BTW got any thing you can tell us about this mystery gun , ill keep it on the







LOW
KEY

u mean tell u about it in pm or on here...well i cant reveal alot but i can say some stuff...

1. it is a homemade piston valve....the piston is machined from teflon and is within a 1000ths of and inch so i dont need orings.....

2. it has a custom paintjob--moms and artist...

3. most of it is copper.....

cant tell u anymore....but i will try that sch 40 3/4 thing im still open to more suggestions though....i dont really want my sabbot to go far i want it to be something soft so i can maybe soak some people from like 10 feet away


edit: be back in an hour watching new mythbusters....

So you're going to shoot it at people?

Have you ever had cold water sprayed at you when it's moving really fast? It hurts...feels like a razor. Try drinking out of the "mist" setting on a garden hose to see what I mean.

well spuzi u go on youtube and type in pneumatic cannon water shot...they all shoot at people with water and of course it wouldnt be top pressure but when water shoots out of so big of a diameter it dousent feel like a arazor....only out of small diamter things..like a hose nozzel

This is true. I guess if you're not shooting at me then it's not really my problem.

lol.....ok well still open to suggestions guys i need something that wont kill my freinds when coming out of my gun

Can someone explain whats the purpose of the sabot and if there is a stopper at the end of the barrel keep it in or if it flies out with the projectile (here the water)?

marshmellows enuf said, oh wait, cheese curls!

Seperate from the above post....

Water should be safe if pressured to a moderate low PSI. In paintball games there are landmines and such that are charged with 12g CO2's and then shoot out paint (a supposedly) 15-40 feet.

yes it is safe...but zeig wont marshies get the barrel sticky as hell???

What about expanding foam??? Get a section of pipe the same diameter as your barrel and grease it up so the foam wont stick. Spray some in and then cut it into little sabots. I dunno how well it would work though.

How about just styrafoam it would be easier to get out you can easily find it and it is cheap.

I say forget the sabot all together but put a drain valve on the gun somewhere, like a spit valve on a trumpet or sax.

No, no... don't forget about the sabot.
In my experience, unsaboted water scarcely moves. Which is boring.

On the other hand, the only thing you'll get which actually stops all the water from flowing is something with an O-ring or such device... so you should probably get a drain system of some sort.
