Ive been working at this for a while and Im finnally almost done.Today I went to lowes to get some 1.5in sdr21 and got a ten foot stick for 4 bucks.I also got some other stuff to finish it.The chamber is 32in of 2in pipe.And the barrel is five feet of 1.5in sdr21.

heres some pictures

I didnt put it in the show case section because it is not yet finished.Any comment/suggestions are highly appreciated.If you want more info on the piston visit this link

EditEdit:Could some body please GGDT this for me

Okay sorry for the double post but I finished this thing today and it was really powerful .I have made piston valves before and I would like some comments on how I could make the valve even better and more powerful than it already is.
by the why I dont know why but this valve is very quiet for some reason.All my other piston guns have been very loud. Is this a bad thing.
And a GGDT on it would be nice too.

i think your pilot volume is way to big

You got 1.5" sdr 21 at lowes? I've never seen any there

What do you mean I have like no pilot volume at all its just a cut down plug that goes straight into the tee.You might mean that thing at the back of it thats a secondary chamber that I use to seal the piston beacause it doesnt seal when I just pump into it with my bike pump.

And daberno I was surprised when I saw it there too but they have lots of it its not all the lowes around me its just this one thats closest to my house.

lucky you. next time i go i will have to root around in the back of the rack. I was able to find pressure rated 3" and 4" pipe doing that.

Yea thats where I found it in the back rack.

Was it all dirty and such when you got it? Cuz mine were. I had to give them a bath before using them

Yea most of them were but the ones under neath all the dirty ones are pretty clean as you can tell by the pictures of the barrel.
Edit:Can anyone do a GGDT
and does anyone have any advice to make the piston better
