Rings, Flames, and Paintball

This past week a few of my friends in my shop and I have been going up at night and making some awesome stuff. The machine we use is called a lathe, and it looks like this: It's a pretty amazing machine. Basically what it does is rotate round a piece of metal, (steel, aluminum, copper, brass, etc.) and then using a sharp tool the operator can cut into it creating a smaller diameter, step, groove, threads...and lots more. It's a lot of fun! Anyway, a guy in our shop who has a lot of cool and crazy ideas decided to make a ring. Now it's a pandemic. Everyone is making rings. Pretty awesome. He decided to use titanium to make his first ring. It's stronger than steel and almost half the weight. He's a bit of a daredevil and slightly crazy, but we like him for it. While working with the metal it gets hot, sometimes it burns the surface black from the heat and you have to stop working and wait for it to cool down. But some of us have very little patience. I was working next to him on a school project and all of the sudden I hear him scream an unrepeatable phrase. I looked over and all I see is white light eminating from the bottom of his machine. Metal on fire. That's a first. He had gotten it so hot that the chips being cut off actually burst into a blinding flame. That was funny.
Anyway, today I just came up with an awesome amazing sweet idea. Yes, all of those. Now that I'm learning how and have material, I really want to make a paintball gun, or any other sort of airgun. More on that later.
