    Generation III codename: Big Bertha

     Big Bertha is my first foray into not using ratios for determining the gun configuration.  I must say having a longer barrel on your spud gun is like having one on a rifle, the projectile flies straighter, faster, and makes a lot more noise, well if you use as much hair spray as I do!  I have achieved some interesting results with Big Bertha using golf balls for projectiles, which you can read about at the Range Photos.
