My First Spud Gun

[sgort87]

Ok, just to clear this up... SpudBlaster, SpudStuff has reason to be stubborn. It's because he is right. Almost all ABS plastic pipe sold at hardware stores is cellular core and is NOT safe for pneumatic launchers.

I'm sure you feel like a dickhead now after posting this:

You are truley a moron. Let me clarify.

ABS cell core is not commonly found at hardware stores.
Solid wall ABS is commonly found at hardware stores.
Pressure rated solid wall ABS is extremely rare.

Do some research before making idiotic remarks.

Dumbass...

all you let it go!! ABS or not who gives a flying fu ck!!

Ok the final determination. You can either risk it. Its like runnin with scissors or playing with fire, alotta people do it and are fine, but its still really really stupid haha. So either risk it and if you blow off an arm dont expect anyone to feel sad for you. Or do stuff the safest way and minimize the risk. Its like investing the highest risks are the easiest ones to make. But the safest are often the better choice.

Yeah cool gun but don't use it.

Wow you are stubborn. You are going up against 2 people now. Both with more experiance than you!

Think about what you say before you say it because pissing off a moderator is the last thing you want to do next to pissing off an admin. I am forgiving though. I am willing to immediately drop the grudge as soon as you either apologize or prove me wrong.

You are right in the sense that I have never used ABS pipe or fittings. Though, my electronics boxes are made of ABS (which smells horrible melted). There is reason I do not use ABS for launcher walls and that is because of three things. One is simply that a wide selection is not available to me and PVC is. Another is that it is ugly. And the last and most important reason is that the ABS that is commonly available is not safe for our applications because it is cellular core and it doesn't always say it.

I have looked at all of your launchers posted here and none of them are made using pressure rated fittings.

Let's start with your <a href="http://www.spudfiles.com/forums/viewtop ... t=4712&">4" Over/Under</a>. In the third picture shown, under the hose clamp on the right, it says "DRAIN WASTE AND VENT". The fittings are also clearly DWV fittings. Pressure fittings do not have that shape.

Now, in your <a href="http://www.spudfiles.com/forums/viewtop ... t=4376&">6 Flame Fronts Are Better Than Two</a> thread, you can make out on the right side of the chamber in the third picture that it says "DWV" and a pressure rating is nowhere to be found. Again, the fittings are DWV.

Your <a href="http://www.spudfiles.com/forums/viewtop ... 5&">Friend Tyler's Gun</a> is wrapped in tape so I cannot read the pipe, but the fitings again are DWV. You can tell by the shortness of the socket depth and the fact that belled fittings are used. Pressure-rated bell fittings are extremely rare and have a different shape.

Just so you know, "Sch 40" is NOT a pressure rating. Sch 40 is a thickness rating, not density. Unless it says "NSF-PW" on it, it's not safe for pneumatics.

What say you now, dickhead? Again, feel free to prove me wrong, but I expect to see substancial evidence in your favor such as a picture of the pressure rating stamped on your fittings and pipe. If you can, I'll change my title to "Moron" for a week. If you can't then I'm gonna change yours to "Dickhead" for however long I feel like.

ok spudblaster maybe your hardware stire has solid wall, thats you, but not at any of the stores I have been is sold Solidwall. Cellcore is more common.
ABS cellcore/solidwall=good combustion.
ABS/=pneumatic
ABS isnt the best thing for a pneumatic, maybe it will work but it might not.
PVC is made for pressure.Hence the pressure rating.

ANd to all of you, stop using the words DWV and Not pressure rated as the same thing.They aren't. They sell pressure rated PVC NSF-DWV.

1) Spudblaster, you are a prat.
2) We already knew that from the "fuelling thread"
3) You now have to contend with me as well. And regardless of whether Gort and 'Stuff have experience with ABS (which I suspect they would have), I do have the relevant experience.

Perhaps what you say applies to you. Perhaps it applies to most of Canada.

But regardless of what you have built, the original discussion was about Skate's launcher.
That launcher was almost certainly Cellular core ABS, so was not safe for pressure.

In the UK, most ABS is cellular core, except if bought at great expense off the net. The same applies in the US.

Thus, it is a more than reasonable assumption that it is poor pipe to be using.

Now, as I'm from the UK, I have to be careful how I sprinkle my knowledge on a mostly US forum. I don't want to post anything that I can only prove to be the case in my area of the UK.

You should do the same. Provide useful information to Canadian users, but shut the hell up at other times.

You may be right for you. Just don't tell other people that they aren't right for them.

Now:

My diagonis of your situation is Piedo-oral syndrome. This is a rare condition where almost everytime you open your mouth, you put your foot in it.

The symptoms include a swollen head, over-active mouth, no modesty, and no consideration for others. The causes are as of yet unknown, but if not actively challenged during the build up of the condition, the effects can last for life.

The only real solution is to not open your mouth, although a special programme of strong drugs can have a benefical effect on the condition.

If the effects are not quickly contained, a full quarantine of the invidual is needed to prevent the contagious effects from spreading. This can be achieved through tachy lists, banning from the forum, and moderator preview of all posting.

As of yet, there is little risk of an epidemic, but I will advise the powers that be to instigate a lock-down if the condition persists.

Thanks Jo. Not just right, but hilarious as always.

SpudBlaster, You have provided me with eexplanations, but no proof. I have never heard of 3 types od ABS before. I am certainly up to believing it, but I still have no actual proof. Remember how I asked for picture proof of ratings?

You did show me that the 2" does not have cells, but that is a relatively low cost pipe and can more easily bought as pressure rated than larger bores. Get me a picture of some of your 4" pipe and then we can talk.

Again, I am completely open to believing you if you can actually prove it. I'm not trying to be a jerk. I just need to watch out for the rest of the forum members.

And just because this 3rd "solid core DWV" pipe exists, it is still not meant for pressure, and it should not be used in a pressurized situation while being held. DWV, solid or cellular, is still DWV.

SHUT YOUR MOTHERFUCKING MOUTHS!! NOBODY GIVES TWO SHITS ABOUT WHAT'S BETTER!! COMMENT ON THE GUN HE MADE (VERY WELL BY THE WAY), AND STOP BITCHING ALREADY!!!




AS YOU CAN CLEARLY SEE... I HATE ABS vs. PVC DISCUSSIONS WITH A FIERY PASSION.
