Nice!
How are you going to attach the barrel to the valve, and what is the copper fitting in the bag?

The copper fitting is a coupling. I needa go back to lows and buy some more 1/2 male adapters. 1 to fit to my bb barrel(copper) and one to fit to my extra pvc. So far I cut the pipe and glued the male adapter and cap to it. The coupling will go on my bb barrel so the bb will go through stay in a detent. Now thinking I need another coupling so the bb can be housed between 2 detents. So far it's goin good. P.S I wore a respirater while gluing haha.

Edit: Gun will be finished tonight. The Chamber is done but I just need to teflon tape the threaded male adapter so the ball valve wont leak. Ball valve needs to be oiled a pinch so I can pull quicker. I also need to finish the interchangable barrels =).

Edit: 1ST barrel is done after a trip to lowes =p.The 1st barrel chambers marshmellows and other things that are stuffed down =p. Second barrel is being made.

Weird question, but can you get a close up on your bag of bb's, preferably the printing? It looks like you are using 8mm bb's, not 6mm. If so, then the 1/4" copper will be just fine.

Not to whine too much, but proxywars, you need to compress those pictures. They're like 5 mB each. I have highspeed now but they still take their jolly old time. Also, some of us(crowley for one) have connections with bandwidth caps. It's usually best if you cut them down to a few hundred KB.

Yep sure np. I use 6mm .25 and .28. My barrel has detents which perfectly fit the bb. My gun is finished with 2 interchangable barrels. What should I showcase this at since it is a bb and sabbot gun? I will fire this badboy in the mourning after the 8hr curing.

I butchered the primer. It was sad so you know I let it be free..... The copper is bent but That was the straightest I saw. Accuracy is not a big wtf for me. Its power. I fired a sabbot and it made a small hole in the wall =p. Not bad for MY first pneumatic =p. and btw how can I make a pvc air tank?

1. Priming is easy and doing it properly can make your gun look loads better.

2. Try straightening the copper by putting it on flat ground and gently tapping it with a hammer or mallet while rolling it slowly.

3. You'll get better power with a straighter barrel, and accuracy.

4. What are you using for a sabot?

5. You just made a PVC air tank...

Even if you are new at this hobby, you should think about making something like this: http://www.youtube.com/watch?v=fD1cxik6 ... er&list=UL

Its a really simple mechanism and isn't hard to get your head around but is much more powerful and rewarding than what you are trying to make.
It also makes it more like a 'gun' than a cannon.

The user has an explanation video on his channel if you dont understand it.

Nail and duct tape is a dart... A sabot is used to push a projectile that is smaller than the barrel (for example, a BB in 1/2" PVC).

Build a piston valve.

You don't need a shock pump for it, just make a big PVC one.

I found out 50psi was going through it and I made a thin paper cone with a nail sticking through and it went clean into a 1in piece of wood. I will just buy a 100psi shockpump. For now ima stick with this than make a $7 piston gun.
