This is a instructable for my coaxial golfball gun, or any coaxial spudgun. If you're wondering, a coaxial is where the barrel is inside the chamber, much like a piece of coax cable for your TV.
Step 1: Safety
All spudguns and launchers are dangerous, and should be used in a safe manner in accordance with your local laws and regulations. Using them in a unsafe manner may lead to injuries or even fatalites you have been warned.
