Welcome to the Forum.
As Noel says, plenty of folk willing to help and share their experience.
Since you a little rusty, it might be worth buying and studying books, such as
Stan Bray “Basic Lathework”, or Harold Hall ” Lathework, A Complete Course”
Then, if you want to do more (Not everyone makes locos, or traction engines, some of us make workshop tooling, or things like clocks or instruments.)
I always advise gaining experience by making simple tools. You gain experience, familiarity with the machine, and a few simple tools that can be used for many years afterwards, on other jobs.
But by all means join a club, to meet other enthusiasts, and to learn from them
