I wouldn't! - and as the forum's only regular female poster (Unless someone else wants to own up), I think I have the final say in the matter.

I think the responses to my long, complicated joke are more amusing than the actual joke.

Note that, although it was written in an attempt to be humorous, the concepts where seriously considered and I think the temperature analysis is valid.

I just looked, they are..... i used it to convince my friend to build a pneumatic instead of a combustion....... i dont know why that made him switch but w/e, hes a pneumatic man now!

blb :lol: that was funny. any ways i think that combustions are definitly more fun to mess arund with beacause it gives yolu that awsome BANG however from what i understand a combustion can only be built so good until using fuel would be impracticle. take schmanman S.W.A.T gun it would be insanly impracticle for that to be a combustion. so if you want a huge gun go pneumatic but if you want a portible big bang gun go combustion

and dont just post to get your count up

@Lukemc - what about Sgort's 12" diameter combustion launcher?

I'd argue that combustions are MUCH more practical when you reach large sizes.

I like pneumatics. not much of a combustion guy.

joanna, while maby more practical, I like the ability to hook up the compressor, ram something down the barrel, then BAM!
and, you can get more power out of a pneumatic. most combustions do not reach 90 psi. in fact, I think 70-80 tops, and there are very few except the perfectly calibrated and built metered combustions, weather they be mapp or propane.

last time we did an experiment to find the PSI of a combustion, the highest we got was 63 PSI and that was with a TIGHT rubber gasket ammo slug.

I still like combustion for the reason i can take it out and shoot it off practically anywhere (within reason and legal limits). I don't need a compressor or anything.

i just sigged that.

totally

PNEUMATICS ALL THE WAY! i lost my eyebrows to my first combustion.....i dont like them anymore...

A-98 - You can now assume that same quote was also aimed at you. =]

and ironically, i have a scar on the side of my right arm from where my friends combustion gun blew flame out of his ignition wire holes and yet...i still like combustions...

odd.

If i could find better PVC pipe around here, i probably would be a pneumatic man though.

Here’s my two cents ($0.02u.s.):

Combustions have there good sides, they’re loud, which can also be a downside, highly portable, especially the ones the have the propane tank attached to the side, (I find that to be slightly dangerous, having a tank of fuel beside a PVC, quite often DWV, combustion chamber.). And nothing is cool than the BOOOM and the reverberating echo of an explosion.
But they also are dangerous, people tend to get careless with them, not giving them the respect they deserve (they’re cannon, not toys!), when not made right they can spew flames and burn people.

Generally speaking, pneumatics are more powerful, have a greater range, and, if hooked up to an air compressor, equipped with a breach loading mechanism and the crew is skilled enough, have a higher ROF than most combustion cannon.
But if not built right they are potentially more dangerous than combustion cannon, using a higher operating pressure, if the materials used in construction are inappropriate (i.e. DWV and ABS), than it could meet catastrophic failure and frag the user and bystanders.

In my opinion the risk involved is worth the power of the pneumatic, especially since I only use NSF-PW. And the portability issue can easily be over come with something as simple as a bicycle pump, or preferably a stirrup pump like Brian the Brain posted. Or a Co2 setup if you got a lot of money.

But that just my two cents.
