Little Bang

Unread postAuthor: PCGUY » Sun Feb 13, 2005 12:04 am

<div align="center">LITTLE BANG

Provided By - Big Bang

The spudgun featured here is the one I call "Little Bang." It has an approximately 1500ml chamber and a 46.5" long 1" diameter double walled barrel. The C:B ratio is about 2.35:1. Despite its name, it is really loud. As with BigBang III the construction of the chamber is completely double walled.

Little bang is a breachloader and has a little 12V chamber fan that I run by use of a 9V battery applied across the fan leads. The most interesting part of Little Bang is its ignition system. It features a 20 foot dual ignition wired remote control. I call the ignition system my "universal" ignition system because I plan to use it on future guns. The heart of the ignition system is an electronic gas grill ignitor module that I purchased from Sears for $16.95 + S&amp;H. After some modest rewiring it provides two 5mm arcs in the chamber - one of which you can see in one of the attached pictures. The remote ignition connects to the gun via two "spark plugs" which I manufactured myself.

Lastly, as with all my guns, fueling is all off board. I have included pictures of the fuel meters for Little Bang and BigBang III for comparison.

I have also included a picture of the two guns side by side for comparison.

In this picture you can also see the bipods I've made for each gun, and the stand I use to stabilize BigBang III and keep it from tipping over.

BTW, the orange and maroon color scheme for Little Bang was chosen because I'm a Hokie! That means I went to Va Tech. Of course, the paint on both guns is Krylon Fusion - nothing but the best!

Real nice, You should make them have interchangable barrels, so you could have burst disks, and make them LOUDER :evil: :twisted: :evil: :!:

I love the metering systems, real nice, I like how the copper is polished and the metering tube is red. :D 8)
