SpudFiles

Hey guys! I am looking to create a pneumatic spud gun. It will be quite small and will shoot tennis balls. I have decided to use ABS plastic so that my gun doesnt turn into a pipe bomb. (discuss?) I am going with a basic design of a 1 ft long chamber, 1.5 foot long barrel, and a valve in between. How big should the pipes be? (shooting tennis balls) Where can I buy the stuff needed online? Thanks a lot in advance to people who help.

The pipe definitely needs to be 8'' for the chamber, yep that for sure.

Thanks! Are there any online shops for buying ABS pipes?

ohh shit you actually bought that lol i was just taking the piss because you didn't do any research, i would download GGDT and read the usage page then use it too find the optimal chamber size, im sure you can buy abs online use google to find a dearer near you.

built completely out of standard off the shelf parts.

Visit the plumbing section of your local DIY superstore, make sure you have a bit of cash on you.

OR

Settle down a bit, make a simple combustion which actually works, have some fun with that, then consider moving on.



It's a n00b thing

Haha
Long story short, I was going to do the combustion spud but I was like... PNEUMATIC sounds so fancy! Hence I am now creating a pneumatic spud gun.
Well anyways, if your interested I found a simple pneumatic gun tutorial:

I am scaling the Pvc's to 2.5 inches and making each one 18 inches. Will this work jacks?
(p.s. your link leads to a 404 page!)

EDIT: found a website for buying PVC's
flexpvc.com

that's interesting doomburger thank you for the link..btw, already started your spud gun?hope to see it if its done

Hey no problem cristofkelley.
I will post another thread detailing the build and end result of my simple build, so look around in a few days. I will make sure to pm you the link when I create it! Try to make one too and we can compare our results

Don't use a ball valve, A sprinkler valve opens faster and will allow you to be much more accurate.

Better then a sprinkler valve get a dust collector valve or as eBay puts them pneumatic relief valve very powerful no modifactions needed just barrel and chamber nd your good

Ah a ball valve is is the only thing in the online store I'm using, but I will try look around for a sprinkler valve or a dust collector valve. Thanks guys! Will post the build for my gun once UPS ships my orders
