PSR .50cal [final]

Unread postAuthor: Darkside 6ix » Thu Jun 12, 2008 10:54 pm

Well this baby has been keeping me busy for a while. It's not entirely finished yet because I still need to install the fill valve and the pressure gauge. I also need to glue all of the parts together. It should be finished by this weekend but I cant promise anything. If I can pull together 5$ in change...then Ill probably invest in some spray paint. Hope you guys like her.

PSR .50cal (Pneumatic Sniper Rifle)
Barrel - .5" sleeved in 1"
Bipod - .75" with medium sized hose clamp.
2x 90 elbows
1x 45 elbow
Valve - 1" mod sprinkler valve
Pilot - Blowgun (for ergonomics)
Chamber - 1.5"
3x 90 elbows
1x T

EDIT: I spray painted it black, added some pvc caps to the bipod, replaced the dwv wye with a tee and I have some damage pics also.

This thing has beastly power. I can really feel any recoil because the majority of the time I lay down when I shoot it. But wowee, this thing flings a marble pretty far for just being at 50psi.

Ammo (14mm marbles)

I hope you guys like it. This is probably the longest ive spent on a single cannon, I put alot of work into this one.

Looks nice but is that a DWV wye I see? I know you can get pressure rated ones but those sockets do look quite short.


edit: Beaten.

Check the writing on it, if you still don't know post what it says, we can help you out.

The reason there are no primmer marks is because he didn't glue it yet. :wink:
I also need to glue all of the parts together.

The T along with all of the other parts are marked PVC-I. My Elbows have SCH-40 on them which I found as a relief. But I dont see SCH-40 on the T. But why would it be in the pressure rated section of PVC. My local ace hardware has Pressure and Non-Pressure rated fittings divided by a big red line. So does that mean its pressure rated?

Surely it must have more then 'PVC-I' on it.

And by the way, Sch 40 is not a pressure rating it is a thickness rating: http://www.spudfiles.com/spud_wiki/inde ... _Rated_PVC

You can also see thats DWV because of the socket depth.
Your lucky you didnt glue it yet :D

Idk...because at my local walmart the scopes are like 20$ :( Well I just looked up that wiki that MrCrowley sent me and now I know how to identify DWV. I still cant believe Ace Hardware had DWV in the pressure rated section. The whole thing will probably up and running by Sunday depending on whether or not I can go to the hardware store. :shock:

EDIT: call me dumb, but what does wye mean. Is that another word for a Tee?
