Hi there, Helder,
Welcome to Mad Modders.
I suggest that you buy (or borrow) a book called 'The Amateur's Lathe' by Laurence Sparey (it might be Lawrence Sparey). It's an old established book describing lathework, mainly using the Myford ML7 as an example. However, most of the operations described in the book can be 'read across' to other makes of lathe.
Also, investigate the range of books published in the 'Workshop Practice' series. (Google is your friend!)
Then you'll find lots of instructive videos on YouTube, especially many by Doubleboost who is also a fellow Mad Modder.
You say that you're short of time - there's no instant expertise-transfusion, one way or another you'll have to invest some time and effort. Still, don't let that put you off, everyone starts from substantially the same place and you can take it gently.
Once you've read Sparey's book (and maybe a few others) and watched some videos, you'll have lots of questions. That'll be where this Mad Modders site will be able to help you. I've found folks here to be very helpful and positive.
