I need it to be threaded so it can attach to my piston valve i have.

I have been looking at all the hardware stores and I can not find a 2 inch pvc threaded street elbow. I have found them on mcmaster but they are 10 bucks, same with launchpotatoes.com. Anyone know of a store and or site that sells these for reasonable a price?

I just sleeved 2.5 inch pvc into 3 inch pvc and the soda can fits perfect. I wanted to save my 2.5 inch for tennis balls and I was inquiring if there a different way to make a soda can barrel. I checked "How-To" already and I did not find anything.

If you need the launcher to be portable you could attach the bike pump to the launcher as I did. I have a small chamber and it takes me a 30 seconds to fill it up to 100 psi.

The paintballs: if they are wrapped tight the will stay together and burst on impact, before the game I plan to shoot this ammo at my old mask. I know the mask can probably take it fine but...

Its launches paintballs wrapped in saran wrap, the occasional potato, and (my friend has a heat sealer) plastic bags filled with colored water. You might be wondering why th...

I am in the process od building a combustion launcher with stungun ignition, propane metering, and a chamber fan. I have looked at many other lauchers for inspiration and I was wondering, what is the most prefered method for making grips? I was thinking of using a tee fitting, cut in half, and using...

Is the fan you have in the chamber? From the pictures i viewed it appeared that the fan was external. And if it is external, what kind of fan is that and where did you purchase it? Any info is appreciated. Very nice cannon.

I recently ordered 10ft of 2.5 inch pvc and an adapter from mcmaster. I got the shipping charge today and it cost me 50 dollars to ship it. So I was wondering are there any other plumbing supply stores or websites that carry 2.5 inch pipe? I am aware that 2.5inch pvc is for sale on spudtech but I ne...

Nice, about how much did you spend on the project?

could you provide me with the link to the QEV on mcmaster?

Where is a website that sells 1" QEV's

Where is a good place to buy 3" to 1" reducers?
