Spudgun Build Help!!

[doomburger]

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.

[doomburger]

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

[Crna Legija]

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

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

[doomburger]

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
