SpudFiles

now i never built a potato gun (yet) and im looking to build something small pneumatic that i could use a bike pump to use it, and im looking to use chary-tomatos as projectiles. im not expecting for plans to build one (it would be great but) so i just need help with what i need to use how to use it and etc.
10q from Mr. Beaver

(if someone here nows hebrew and could help me it would be great............ lol XD)

I don't understand your question. What don't you understand thats keeping you from building? Try and be more detailed in your questions.
Welcome to Spudfiles.

Omg that was what my first gun was. Use like a 11/2pvc tank with a sprinkler valve or a 3/4" ball valve. Use 1" pvc for a barrel cus i know cherry tomatos work good with it. pm me if u desperatly last hope need plans. try it on ur own

'bout as simple as it gets. And like gunner said, 1" PVC is good for cherry tomatoes.

Have you done any searching? Try and research some on the spudwiki there is lots of useful information. Sorry if that sounds a bit rude.

I agree with BigJon, he needs to have actually research. You cant go waltzin in and asking for plans. We are not in pre school and spoon fed everything. Im just saying you need to take the initiative to look because from what i see you have no knowledge of how a pneumatic works. So learn the basics by starting with the spudwiki.

Once you get a general idea, then if you have any questions that cant be answered searching, which is almost none, then i suggest ou make a post.

dude thats kind of wrong cause i didnt asked or expected anyone to give me plans i just wanted to know what should i use and how cause its kinda hard to get it, everywhere i checked its all simples and stuff for ppl who already understands it.

I also wanted to know what machneri il need what exactly is tapping and where can i get it all.....

Once you have your layout, or however you want to build it, it is suggested to use a sprinkler valve. These can be modded for better performance.

Tapping, basically, means to cut threads.

Sprinkler valve vs. ball valve
Quite simply, the sprinkler valve opens faster, giving you more power. What you need to tap it (you are referring to the sprinkler valve right?). All you need is a drill with a half inch bit to drill a hole in the top. (check the how to section or the video here)
For supplies, it depends where you are. What country do you live in?

EDIT: hey! You stole my thunder.

I live in Israel and from how it sounds ill think ill find the stuff at home center but btw i asked what machinery i need to have to build it so can someone tell me plz...

A hacksaw, a drill and bit, a tap, a flat file, a piece of sand paper 100 grit, a vise, and the most importent tool of all -- common sense!

whats a flat file? excuse me for my lack of knowledge, and also in 1 video i sow he used some kind of tape to wrap the lower part of something before he connected it to the PVC what kind of tape was it?

Ma Shlamech?

I don't see why you'd need a pipe tap, if you're using PVC, the threads will pretty much carve themselves using steel fittings.

A pneumatic cannon is incredibly simple- Just two pipes with a 2:1 (or 1:1) volume ratio and a valve in between. There are some plans in the "cannons" section of this site, and a very good guide on modding a sprinkler valve in the how-to section.

I'm going to assume any tape used in a spudgun is Teflon tape, which helps seal the threads.

10x hehe, tov toda, you have a future.... with hebrew.

so anyway im seeing always the sprinkler valve but i don't know how the ball valve looks and anyway what with all those guns handles and triggers attached to a sprinkler valve, do they really work and how also can i use this with ball valve??? can i use an old cap-gun i have like toffy gun style??
