i am a one man band. i am a chassis builder and i have a vf-3 which i try to only use for multiple run parts so i can continue welding and only stop when my green light is flashing. im thinking of adding a lathe to my shop for making threaded tube adapters and what not. it needs to be self sufficient for the most part. not like a tl series where you still have to "man" it for some of the time. what would be a good starting lathe? im not afraid of getting a used older model to try and save some loot. maybe like an hl-2? or would it be worh it to get a new small lathe like a gt-20 or even an sl-20?
