thanks i will remove it

hey i just saw your post and it reminded me of a pop bottle gun i built last year, it could shoot a homemade dart almost an inch and a half into solid wood, at 25psi it was cheap and easy to make, and the design was expandable, if u want the plans just message me bak

how unsafe is cellular core, i was only planning on using it up to 60 psi max, what if i covered it in aluminum sheet metal, i have some lying around
