I hope this isn't to basic but I am still learning and I have noticed there is always someone asking for projects to start with when first starting out. Its a keychain with a small storage compartment. My daughter is graduating high school soon and joining the Coast Guard and I figured I could stuff a $100 bucks inside of it for her so she would always have some emergency money with her since she will be away from home. She is pretty good with her money so I don't think she will use it for shoes or a new purse..lol. The threads are 1/2-20 and I used a tap and die to cut them. Still haven't learned to thread with my lathe yet.
