The PG Update damage pics

Unread postAuthor: bigbob12345 » Mon Feb 18, 2008 8:28 pm

Okay so this is my most piston gun that I just finished today.
It is not my first I have made quite a few others but this one is my favorite so far since it is so nice to hold.
I named it the pg beacase it is a pg(piston gun)

I dont know the power yet Im waiting for the glue to dry Ill put up some damage pics up tomorrow when the glue is dry.
It costed a lot more than expected I expected something like $20(already had the sprinkler) but it costed $30 still not alot by spudgun standards but it is a lot to me off my 8 buck a week salary.
I dont mean to brag or any thing but check out my priming job I dont think there is a single stain. I have always done a pretty good job on priming but this is definatly my beat priming job yet.Im done bragging.

the specs
Chamber:2ft of 2in pipe
Valve:1.5in piston valve with a 1in porting piloted by a 3/4in sprinkler
Piston:1.25in pvc dremeled down to fit in 1.5in pipe
Barrel:I dont know yet I havent bought it yet

Pics

the gun(I know the pilot volume is unessecarily large)

I really is nice to hold

Update impressive damage shot and added a golf ball barrel and replaced the ball valve with a 1/2in plug.

The gun with the barrel on
Image

I shot at a 2 by 4 at 100psi with a golf ball
recoil knocked it off the chair it was standing on
Image

I got a lot of splinters trying to put the peices of it back together for this photo.

lol, you make it sound like you have a job. For $8 a week, I'm guessing its allowance. :wink:


EDIT: oh, and btw...very nice gun for $30 bucks.. It would cost me that just to get the sprinkler valve + gas.

Looks clean. I've never actually got around to making a fully operational large scale piston valve, and my 3/4" porting steel barrel sealer was just recycled as parts for a 2" porting TBD valve.

JSR's going to have a heart attack when he sees that pilot volume though...

On an unrelated note, you really need to do something about that $8/week "salary" of yours. There are always ways to make some easy money if you put some thought into it. With some creative setup I made a profit of $200 on a lemonade stand in 1 day. Of course, I now have a job, which pays better (and is significantly more legal) than my former ventures.

You would be right there every now and then I do some extra work and up that to $13 a week.

DYI:I dont think JSR will like the extra pilot volume very much eighther but I wanted a gun that was nice to hold and thats what I got.

Edit:Dont ask what the ball valve is for.

I got my job when I was 14. Lots of my friends got jobs when they were 13. I'm thinking that you're just a procrastinator, and your desire for money hasn't quite overcome your laziness yet :P

Shmanman:Okay the ball valve is there for no reason whatsoever .
it is there beacause I didnt have a 3/4in coupling to use where that tee is so I used the tee and the tee needed blocking off at the one end and I just had that conveinently and put it on it reduces to 1/2in threaded so Ill take it off next time I get to go to hardware store and get a 1/2in plug to replace it.
Happy now

Edit:god i just relized i just used one whole sentence explaining the entire thing my grammar really does suck.

DYI:Im not a procrastinatorexept in school
I dont even think you can get a job at my age where I live i think you have to be 16.

Very interesting setup. There is enough pilot volume there to add another barrel to the other end of the sprinkler valve. It looks like a nice build and must be fun to shoot.

Elitesniper:A3/4in sprinkler is overkill for a 1.5in piston so adding a little more volume wouldnt effect performance by more than a couple fps.

sthorne:Mercer Island washington it says in my profile

Origin unknown: did you steal that second barrel idea from me since Im sure Ive metioned it and iv done it before.
Or did you just come up with it yourself
