This is strange. My local Home Depot has them in the Irrigation isle. Their online website lists several models that are in your local store and not for online purchase.

My local Home depot doesn't carry sprinkler valves either. I just order mine from Amazon.com

I'm not ripped, that's my son the Mauser donater.

hah, my bad Though you could have just claimed you were him and we wouldn't have known.

I always thought it was Hans.

And yeah, it is Han Solo. See?

This started life as a Star Wars laser tag gun. Yes, in a galaxy far away, Hans Solo chose the Broom Handle Mauser as his side arm. Mine's 100K volts, his is a lot more.

I'm guessing it's just a typo, but it's Han Solo, not Hans Solo

Here's a few pics of my second spud gun, ready for expert reviews.

Put a shirt on. Just kidding, you look fairly ripped. anyway, it looks like a nice, solid gun. How's its performance?

A QDV has no pilot valve. You're assuming instant opening time on the pilot valve with your estimation. A normal piston valve also has some resistance to the piston moving back produced by the not-yet-vented pilot volume, a QDV does not. GGDT actually models all these effects, if you punch in a pis...

How would a QDV have a faster opening time? As I see it, when you're pulling open the QDV with your finger as in this gun, you are opening it with, say, a max of 30 lbs of force. And if you had a pneumatically actuated valve with 400 lbs of pressure it would have ~ 400 lbs of force pushing it open (...

Uh, I didn't want to seem to reject your proposal without consideration, I'm not saying that you're wrong or whatever else ! I'm just saying that the actual system is way powerful enough for me, I'm not trying to reach the max efficiency by adding pneumatic mods Wink I have a preference for mecanic...

Ewwwwww Pop Rock.... lol That's a pretty nice gun, though i'm more of a pneumatics guy

Please explain the pump too

Im guessing its a sturrum (Spelling) pump that uses a bought check valve?

I'm guessing you mean a "stirrup pump"?
Here is a how-to page on how they work and how you can make your own. hope that helps

I don't think that using a pneumatic triggering system is a good idea, it would add a lot of pieces and complexity, for an infime gain. For me, the main interest of this firing system is it's simplicity ! It's cool. It was just an idea. After all, it would add efficiency, and eliminate the need for...

Hmmmm. I'm liking the spool valve and especially that onboard pump...you could have the QDV activated pneumatically with a schrader valve, blowgun, or even a pushbutton or hammer valve...Anyway. Nice build! Also, I like how you're wearing gogles and gloves when you're shooting! Just a thought. You c...

Your probably right mate!?,Looks and sounds to have decent power too= its the same guy who made this beast!

Sweet gun, but what a waste of perfectly good soft drinks!!!

That's quite a nice gun you've got yourself there, django!

Yeah, it's a powerful pistol, but it looks way too big to aim accurately.

HAHA I was just in Cincinnati today!!! Nice city. I know UC has a good music program, but I don't know much else about it. Not that that really helps you lol :D Anyway, I know two people who studied mechanical engineering at the University of Kentucky, and they both got very high paying jobs right o...

Haha. Wow. That is one long-ass mother!! Looks to be a lot of fun to shoot!! Nice, interesting build!
