Welc ome to the Forum.
You will m,always get help on here, but do find a local Model Engineering club and join.
You will find like minds, and learn from their experiences.
FWIW, my advice would be, before launching into a model, where a mistake could be expensive, gain experience by just maching odd bits of metal.
If you make a kistake, you mwill learn, mand the sacrap will have some value to you for just that reason.
My advice would be to learn by making a few simple accessories. A centre height gauge, to aid setting tools to the right height, then perhaps a Slidingf Tailstock Die Holder.; and using a small drill chuck, a Sliding Tailstock Tap Holder. (You can use the same tailstock arbor for both)
If you turn something a bit undersize, it will not be a total disaster, you just machine the mating part to suit the size you have, so experience gained at minimum expense.
Don’t rush into using carbide tips. You will learn by grinding your own HSS toolbits. And older machines were not designed for the speeds and feeds that optimise carbide.
Carbides have their uses, but walk before trying to sprint! It used to take four years before becoming qualified as a skilled turner.As you gain experience, you gain skill mand confidence.
Once, none of us had even seen a lathe, let alone used one. We all had to learn!
