My first paintball gun

Unread postAuthor: nth_power » Thu Jan 05, 2006 1:55 am

After viewing many sites and studying a host of fine spud guns, I decided to attempt one myself. I think it turned out nicely. First paintball gun.
Bolt action breech loading
2 reservoirs with a regulator in between
Direct compressor hook up and on board bike pump
Functional silencer

some explanation of the works

Unread postAuthor: nth_power » Thu Jan 05, 2006 4:20 pm

Yes, that’s a modified sprinkler valve with blowgun activation. I have two air reservoirs, the big one (the main reservoir) towards the front of the gun and the smaller one (the firing reservoir) with a regulator and shutoff valve in between. This allows me to fill the main reservoir and get several shots out of the gun with just one fill. I fill the main reservoir and close the valve, cock in a paintball, fire, then open the valve to fill the small reservoir, and repeat process. At 125 psi I can get 5 good shots at a regulated 40 psi per shot.

Looks like you got the whole look thing down, but how about the preformance? Hang-time? Nice gun. This gun defently needs paint though. Possibly post a pic of the loading mechanism? Looks good man, like the blowgun by the way?

The gray area towards the front of the coupler is JB Weld. Yeah..... i messed it up and had to fill it back in. I thought if I shaved it down it would kinda scoop the paint up and keep more than one from going in at a time. But it

I compare tested it to my cousins $200 paintball gun setup. Not only does this gun shot as far as regular paintball gun, it is actually more accurate. The longer barrel makes it far more accurate. Also, using my on board regulator, I shot a paintball at 90 psi and with out really thinking about what I was doing........shot may car and it shatered a chunk off of my gas cap. :cry:

I like this gun a whole lot!! Looks like one of the best in PVC so far.I do have a few suggestions however.You have a lot of room underneath the barrel to extend the primary chamber forward.
Bigger primary chamber means more shots.if you also increase the diameter of the secondary chamber you get better performance AND extra shots!!! These moderations won't affect the overall look
.About painting it: try cutting pieces of bike inner tire to sleeve( outside) most of the pipes instead.That way you get a satin black gun with a rubber coating to help prevent damage or scratches when you bump it into something.Also it makes the PVC pipes stronger.I do it on my guns and it works great.U can use different sizes of tire or cut smaller rings so it's easier to stretch around bigger diameter pipes.Build up a sleeve from smaller sections that way.
These are just suggestions.Your gun kicks ass as it is.My compliments

Is that a bike-pump on the primary chamber? Lovin' it! :D
How many pumps does it take to fill lets say...40psi?

When I was first building the gun I thought about having a bigger primary chamber but I didn’t want to make the gun any bulkier then she already was. I love the inner tube idea, I’m goona try that!!

20 full pumps will put at a little over 40 psi

wow that thing is a-m-a-z-i-n-g you've just inspired me to create a paint ball gun, i love the idea of the two chambers what size are they? is it alright with you if i build one similar to this? also did u use any kind of stopper to prevent air from going into the stock on that tee?
thanx

The only reason I have this gun is because I got on this website among others and was inspired. So, to anyone who may be inspired by my guns I definitely encourage you to try replicate or improve upon this design.

The main chamber is 10” of 2” pvc pipe and the firing chamber is 6” of 1.5” pvc pipe.

As far as plugging, I drilled out about half way into the tee that the stock goes in. I cut a little piece of pipe with one side at about a 45 degree angle and filled it with JBWeld. Glue it inside the tee with the angle creating a nice little sweep to direct the air out the barrel. It acts like a 90 degree and keeps the air from traveling around in the stock

I haven’t had time to try the tubing idea because I’ve been working on a gun that is a powerhouse. I’m done with the construction, I'm just working out some cosmetic details. It shot a golf ball over ¼ mile the other day!!!
