I just wanted to make an official apology for the really poor management of the Spudguns Yahoo Group over the last year or two. I've been incredibly busy with...
Rusty, I have been watching the pending members and approving those that looked like they were interested in the “art”. Things have been rather quiet. Dan...

10-04 Rusty, Fill a plastic pipe with an explosive, ignite it and someone gets killed, or injured....DUHH! * It's called a PIPE BOMB ! Stuff like that gives...
I have been active in the fireworks hobby for the past few years and we have the same trouble. The reporting of accidents is terrible and not precise in any...
Does anyone know William Mark Worden? I think he was in Washington state and was a member here years ago. Thank, Dan Thames http://pyrodan.privatedata.com/ ...
I'm making my first pneumatic spud gun (made many combustions before), and I want to do it right the first time. What I want to use is a piston or supah valve...
Carl, There has not been much message traffic here in the past few years. However, there are still some of us diehards around. I don't know about tutorials,...
So I've been reading alot about piston valves and am about to build my first one, but I have about 3 questions. 1.)I'm wondering if there are any advantages...
Carl, I think that you might be confused (or it might just be me as it's been a long day, please bear with me) The piston seals at both the barrel AND at the...
No, I'm not making a hybrid, I understand how the valve works, but there definetly are 2 different sorts of configurations you can make, I've seen plans for...
i'm not really sure as if there is a performance difference between the two, but my suspicion would be that a barrel sealed coaxial gun would suffer a little ...
I am trying to make a supah valve, but am having some serious problems keeping it from leaking. my design is a chamber sealing valve, and a lot of m leaks are...
Hi, Gang, I'm the new guy. Basic intro of sorts is that I'm a retired mechanical engineer who's transitioning into becoming a high school teacher. Right now,...
Hi Lynn, I've shot rags as a test projectile in my gun and a friend of mine shot a wet rag through his garage wall. Seems to me a tightly wrapped T-Shirt would...
Hi, Jack, Your reply cracked me up. No offense at all, but I can see how you'd think so. You guys are into launching honest-to-gosh hard projectiles over the...
Hello again, I've been through something over 3,000 of the posts in this group, but one of the things I have not seen yet concerns glues and techniques for...
Hi Lynn I like the one Gorilla PVC Glue which is a one step glue (it doesn't need the primer). It seems to have a slightly longer set time, so you have to...
The CO2 bottle output to about 60 PSI into an accumulator, then dumped via the sprinkler valve should work well. I have seen these in action at college BB...
Lynn, I think there is a write-up out there somewhere in those old messages. From what I recall……. Make your pipe ends very square. Chamfer the outside...
Hi Lynn, I guess I'm out of step with the times. My daughter (now 32) was a "jock" all through her school days. I think there are few things funnier than half...
That all makes sense. Thanks for posting it. What about cleaning or prepping the mating surfaces. Would light scuffing from, say, white Scotchbrite be of...
Don't feel bad, Jack. The first one I saw was probably three or four years ago at a hockey game. We had a semi-pro team here at the time, and between periods...
Glue “body”: If you go to a store that has a lot of different PVC cement, study the labels carefully. There are normally 3 different types. Normal, ...
Ha, Jack i've done the same thing with a shop rag, thinking "they couldn't be that destructive,could they?" at 100 psi mine will cave in the side of a 30 ...
