Would you reuse these rotors?

I always wanted a lathe,never run one. So i found one that was affordable. 1947 southbend.
Then i watched tubalcain videos on youtube. Smart feller. Learned a lot.
I can do the basics on a lathe. I have turned a barrel, crowned, chambered etc the only thing I didnt learn was threading and it basically does itself you just know how to set it up change the gears etc.
