There has been some talk going around about a spud gun build off. I got some info from a "higher up" that there might be something. I made up some rules and )DEMON( said there should be a 2 month timelimit.

i thought that i might help by posting the rules in this thread
SPUD GUN BUILD OFF!

Categories-
1. Level 1 Combustion
2. Level 2 Combustion
3. Level 3 Combustion
4. Hybrid
5. Mini Hybrids
5. Level 1 Pneumatic
6. Level 2 Pneumatic
7. Level 3 Pneumatic
8. Mini pill bottle Combustion

RULES-
Level 1 combustions-Can only use 1 spark gap, a BBQ igniter, and only spray deodradent. No propane and no MAPP gas. No stun guns.
Level 2 combustion- Same as level 1 but you can use stun gun ignition, But still no propane or MAPP gas only spray deodorant or ether.
Level 3 combustions- You can use any thing, nothing is restricted. Just no hybrids.
Hybrids- Like the name says.
Mini Hybrids- No restrictions except the chamber cannot be bigger than 2”.
Mini pill bottle-Can only use a piezo, a pill bottle and spray propellants.

Level 1 Pneumatic-Basic, ball valve triggering. No sprinkler valves, QEV, or piston valve.
Level 2 Pneumatic-Sprinkler valve triggering (Modded or not) No Piston valves or QEV’s.
Level 3 Pneumatic- No restrictions you can do anything and use anything.

also, how about diaphrams, and burst disks?
in the upcoming presidential election, there will be several candidates who will be running, one of whom is Hillary Clinton. Now WAIT A SECOND!!! I though there was some sort of rule that prevented someone from serving more than two terms in office. Vote Against Hillary: Presidential Elections 08

These are rules that wow came up with:

Categories-
1. Level 1 Combustion
2. Level 2 Combustion
3. Level 3 Combustion
4. Hybrid
5. Mini Hybrids
5. Level 1 Pneumatic
6. Level 2 Pneumatic
7. Level 3 Pneumatic
8. Mini pill bottle Combustion

RULES-
Level 1 combustions-Can only use 1 spark gap, a BBQ igniter, and only spray deodradent. No propane and no MAPP gas. No stun guns.
Level 2 combustion- Same as level 1 but you can use stun gun ignition, But still no propane or MAPP gas only spray deodorant or ether.
Level 3 combustions- You can use any thing, nothing is restricted. Just no hybrids.

Level 2 Pneumatic-Sprinkler valve triggering (Modded or not) No Piston valves or QEV’s.
Level 3 Pneumatic- No restrictions you can do anything and use anything.



There will be changes. This a compitition where anyone can join, those of you that think of it as a joke don't have to do it.
I think that there should only be a closing date and not a starting but getting money is an issue, mabey this can be a thing for every year. I think there should be less catagories, something like:
combustion light (mainly portible, can be mounted)
combustion heavy (not portible,mainly mounted,would be kick ass on rails)
Hybrid(light/heavy, you get the point)
Pneumatic( light/heavy)

An international projectile, being a certain mass and size should be used for the preformance judging catagory. Then there will be other catagories like coolest, best paintjob yadda yadda yadda.

Of course there will be Gorts getto award, there will most likely be 3 top cannon and the prizes will have to be discussed.
It is late where I am right now and I have left out details. Please state comments about the rules and such. Critisism in not needed. :P

*edit THANKS BEEBS!

I think you're gonna catch some crap on the hybrids. Pure O<sub>2</sub> enriched combustions can or cannot be considered hybrids. So somebody could really submit an O<sub>2</sub> enriched combustion as a level three combustion.

no? By hybrid all that would be considered for the contest is something that literally has somewhere to inject air into...

What is the limit on the number of guns entered by a single person?

Hint: chamber size restriction for minis should be volume-wise, not lenght-wise. You (in theory) could have a 2'' long chamber, three feet in diameter. That wouldn't be very "mini".
This sounds like a terrific idea. I feel there should be a category for non-standard launchers, too, like the acetylene detonation cannon or spring-powered pneumatics and such. Or would these be included in the Level 3 combustion/pneumatic section?

with the pneumatic judging for level 2 you could build a freaking huge cannon with 3chambers and 3 sprinkler valves to all hooked up or something.i say if you have two ball valves your level 2 and if you have 2 spinkler valves your level 3 and there should be a restriction on size for level 1 and 2.
and for a universal type projectile you could use golf balls. and you going to have more problems with barrel diameter bigger can be better you just get the heaviest object that will fit and you will well should out shoot anyone.and if we use GBs we'll make pimpmann a rich man :D

yah iv been using oxy-mapp cannon (it finily crackin at the 90 degree angles) it very powerfull the tater is out of sight in under 1 second, im gona build another over-under but the 90 degree angles ar gona be sch80 along with the chamber

I think taterz are better suited for ammo since some of us (cough) use different standards for pipes.
Plus, how is one suppose to make a GB mini? :lol:

Just some input…

If you were to ask me, there is way to many categories. And even if you win you feel like a grain of sand on the beach. I started a big discussion on Spudtech about is it a “hybrid” if you add pure O2. DR said it was, although if the 02 is only used to replace a atmosphere it will not generate that much power as a hybrid using compressed air as the atmosphere. Seeing as the topic is still kinda a hot, I would still merge them for the simple fact that both are similar in theories, and not many of the two get built. While im at it let me try my hand at new categories.

-Small Scale Launcher (chamber volume could be the determining factor, and could be ANY type of launcher)
-Large Scale Launcher (this would also be regardless of pressure generating process and only awarded for sheer size and power)
-*Bling-Bling*(Won by sheer jaw dropping looks)
-Concept award (this would be awarded for new concepts, and or a perfected concept of late)
-Best Combustion
-Best Pneumatic
-Ghetto Heisman (Still in the approval stages, but essentially another way of saying “good job” to that duct tape wonder)

Proably missed something, but you get the drift, and ill be here to further answer questions/details.

EDIT- Ill take that back, its hard to chop down the amount of categories. Although I dont really think all the awards in other systems should be based off the type of pressure generation.
