Ditto.
Got my first metal fabricating education in 1987 after a 3.5 year apprenticeship.
A "big" lathe can kill you, a small hobby one i assume can also still take a serious bite off you.
Dont touch shavings while the lathe spin, they are like rope razor blades and will lay bare your bone in a heartbeat
I assume you will only use HS bits, i dont think a hobby grade machine can push the big boy cutting tools,,,,, HS is also fine i often used it as you dont have as big a cutting pressure and so can lathe thinner long things.
Biggest lathe i ever operated had train wheels in it, thats 4-5 foot diameter, biggest grind i ever did,,,, okay helped with was train engine crankshafts.
Still peanuts compared to the ship engine crankshafts i have been standing on / crawled / walked around below, you look up and think " no wonder this SOB top out at 95 RPM "
