NO GLUE AND SCREWS NEEDED!!!    Hi, my name is Daan. I'm 14 years old, and I made this V2 air engine. The V2 air engine is easy to assemble and runs on low pressure. No glue or screws are needed. This is what you need: pliers and sandpaper.
My tutorial will be online soon at daans.engine. on YouTube.
See you soon!       v1 and boxers are coming soon! you can connect the engines
