Step 2Introduction to Assembly
You will need various other parts: Super glue, wire, battery connectors, nuts and bolts,etc.
If you decide to build this project you may need to improvise on various parts and construction.
All the parts I used may not be available to you, or you may have a better idea about how to construct this project . Either way , you need some building skills and good old fashioned rigging. good luck.
WARNING :this project has the potential to be dangerous as you will be igniting compressed gasoline vapor and using a high voltage coil which could result in shock. If you make this gas powered soda bottle rocket, please use your head ,wear safety glasses and protect your hearing.
I have shot the rockets for years and have yet to get hurt, but if you're careless , someone could easily get hurt.

Dude, shock is the least of your worries. You are using Sched 40 PVC I think, maybe not, but it's max rated pressure decreases with size. In your 3" size it's only about 120 PSI. When your compressed fuel/air ignites you're probably pushing 1200 psi. A high speed camera might indeed show the chamber swelling like a balloon. You need to use Schedule 80 PVC, completely sterile and clean glue area, 48 hours cure time, then wrap the whole thing in a blanket or get a shield. I've done this for a long time, had some cannons blow all to hell just missing my face and once sticking the piezo igniter in a tree behind me!! You have a great design it's just under-built for the pressures. My 2ç worth!

Actually the pressure is never contained in the pvc, The ignition chamber is inside the soda bottle, the only thing that may rupture is the bottle in which case the ejecta will shoot out the front of the bottle. This isn't a spud gun. It isn't built to hold pressure its just a launch assembly. Thanks for the warning though.

I need to look more closely... my apologies.. but Sched 80 would be safer just in case... You can buy Clear PVC in short lengths but it's hella expensive, like $15 a foot for 2"... might be cool to build a demo gun out of that—it would be totally transparent for videos etc. Anyway, you've got a cool design and sounds like you're pretty safe... just remember Murphey's Law... "What Can go wrong Will go wrong"... I put my stuff behind an old Plexi MC Windshield now.. lol
