"you need a very small chamber" or "a lot of paiteince"

It will indead light the mixture. Wheather or not it pops out and takes out a window is debatable, as is it's reliability.

Personaly, I use POV-Ray to do my renderings. It has some really advanced options, but doesn't come with premade libraries of objects - you have to make everything out of primitives, no shortcuts.

Not to mention that you have to learn the syntax & vocabulary...

Ok, I'll Point out a issue: your including everthing anyone has ever shot in the regular ammo list. I would steer the regular ammo list towards a list of common house hold ammo for certian barrel sizes - a 1" list, a 2" list... (no BMX pegs) Also, having a "ammo you can eat" section, although funny,...

Ok, some ammo I made: http://img.photobucket.com/albums/v611/car2/BoltAmmo1.jpg Seen here, sitting next to it's sabot. One of the main ideas here was that it would be easy to remove from anything it imbeaded it self in - simply screw it out. Also, it's heavy (maybe 130 grams) and quite aerodynamic, ...

Just wondering, what's the formula for the amount of SBs you get for a post?
I would geuss something like the square root of the characters times a constant, but I may be wrong...

Yeah, saying "I'm rich" is the point. Hidden assets (stuff in bank, purchesed stuff) make this hard to asses.
A large amount of SBs indicate that you'v contibuted quite a bit to the forum, it's more informative than just the post count.

If you can't get a nice picture under 250KB... either your camera skills suck, or you are using a .bmp
You could also try cropping your images; I'm interested in veiwing your cannon, not your room.

Your buggy casino has destroyed all meaning the spudbux once held.
Heck, having people able to buy hard to see assets, or earn intrest by hiding stuff is bad enough...

I think we should have an ammo section; like our combustion, hybrid, and pnematic sections.
All you'd have to do is modify the board so it has 2 new catagoryies: submit ammo, and official ammo.

Yeah, there certainly is a way to quiet a combustion, it's called: a longer barrel.

Seriously, make the barrel long enough that the C:B ratio is .7:1 or .8:1, and it will be pretty quiet.
It will make it more powerfull too!

SaladTosser: Yeah, you get "net recoil" (the gun has velocity after firing) from a dryfire because you launch the air, and air has mass. I guess that you typicaly don't call air "ammo", but anyway... Yep, If by 'estimated projectile speed' you mean what, say, the GGDT (which assumes a unmoving gun) ...

What shape, size is your chamber? You might be having trouble getting an isomolar distributation. Because you used steel for the chamber, your probably not going to get a new, large diameter one. Try a chamber fan. I regard a cannon failing to fire with a weak spark a symptom of other problems, in t...

Yeah, I hate age discrimanation too! Yesterday, I found out you can't buy epoxy at walmart 'till your 18+! It seems that policy-makers don't understand the practice of mischeif... we make due - Can't get epoxy? Use something else! Anyway, just bring you mom. Give her the cash, and tell her to buy it...

The weight of the piston shouldn't matter; let's examine a dry fire: .===[] .| === .[]| Initaly, piston forwards, gun in inital position. Piston is pushed back, same force pushes main gun forwards. Piston is stopped by bumper, movment stops. Result: valve opening pulls gun off shoulder. (ammo recoil...
