1. Figure out the assembly as the figure...drill bunch of holes..tape and glue gun + CA to secure assembly.
2. The spark goes into front section of 40mm PVC pipe
3. at the rear end of 15mm pvc pipe secure the inner section with a little glue gun adhesive to make sure the marble will not slide down when the gun pointed to earth.
Spray denatured alcohol (you can buy spirit from any hardware store) 4-7 times (the more the stronger fire power) into the D cap and close it. Insert marble from into 15mm pvc pipe. Press the trigger and shot...
This is a high powered spud rifle. This project just for fun and never intended to harm others be it people or animal. Never aim at people or animal or in crowded area. Look for large empty place to test this marble spud gun. And also never aim at target that can bounce marbles back and hit you or other people.
