    Ok the seller said it is a old lathe (30 plus years) the motor has stamped 1982. i know the are many 1940 and older working lathes.

    My first problem is that i have to run the motor is a 3 phase(220/380) on a single 220v line.
    I can buy a new 220v single phase motor or the cheaper version is to add a capacitator to the 3 phase motor and rewire it for delta (220v 3 phase) so it can start on a 220v single phase.
    The frequency variator its a far option because i just break the bank for this metal lathe.

    I must also buy a metal knife for the lathe any cheap sugestion? i want a knife that i can swap the cutter tip. i don´t want one that is weld on.

    A 3-phase motor and VFD has a lot of advantages: variable speed, braking, less vibration and a better finish on the work. A single-phase motor will cost about the same as the VFD, much better idea!

    If you have a grinder for tooling it's good to also have high-speed-steel tools, carbide needs more power from the lathe and, more important, more rigidity and the BV20 and similar aren't the most rigid of lathes...

    It looks similar to the Chinese/Korean 920 or 918 lathes, but without the gearbox. Looks to have a geared head though. Certainly seems to share some of the castings...
