The Whittaker "Firefly 0.46" is quite straight forward with plans freely available and could just about be done on a lathe with vertical slide. Liek all the small glow and compression diesel engines fit of parts is everything so pay attension to getting one part to fit another.
My detailed build is here and drawings here , it's the WF46— drawings that you want No 1-20
