Some nice lathe machining there
Must be satisfying for you nearing the end of a long project.
Do you prefer carbide tooling or HSS ? I mostly use HSS for my lathe doesn't have the mass/rigidity required for coping with industrial grade carbide inserts.
Sharp positive rake carbide inserts are available these days but the cheaper Asian brands are not that good.
The chap down the road from me rebuilds Steam traction engines .. along the lines of your work, he has a a horizontal boring machine, radial arm drill and a massive FORD brand lathe. made during WW2.
