Ah I see now! you have enlightened me Thanks!

To lubricate the other side as well, the ball valve would have to turn at least 180 degrees...
I am under the impression that ball valves can only turn 90 degrees. Right?

EDIT: My ball valve looks somewhat like this

Ah thanks, I guess I'll do that. You only need to lubricate one side of the ball valve?

Haha

No luck with finding any unions either...
How can I lube a ball valve with tubes on both ends???

Ah thanks. I have a bottle of silicon spray right next to me! I'm not building a piston because a ball valve is so much simpler
However, I have a problem: How am I supposed to lube the ball valve if there are tubes on both sides? (I can't reach the ball valve)

Hey guys! I'm buying a 2.5" PVC ball valve (can't find a sprinkler valve anywhere) for my spud gun, and someone has told me that after a while it starts to become stiff and harder to turn. Is this true, and if it is, around how long does it last until it starts to become stiff?

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

Looks very nice! A nice coat of paint and that could look real nice.

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

Haha :D 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: http://www.instructables.com/id/Easy-Pneumatic-Potato-Cannon.-Fun-and-p...

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

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. Ho...

Wow well now I feel stupid . Thanks!

Thanks for the reply, but I have no idea whatsoever how to make that lol. Could you elaborate on the process of building it? Also that would be kinda too large for my use (I only have a double tennis court to use it)

Hey guys! I am quite a newbie to creating spud guns, and so I would like your help to get started on my first non mini spud gun. I am looking to build a medium size and power spud gun out of ABS plastic. (I heard its safer... safety first!) I would like to use this spud gun in a double tennis court,...
