I found a Jet BDB-1340 lathe that is reported to be 10 years old, one owner. I took down some notes from it, spindle through hole is 1-17/32, minimum speed is 60 rpm, max speed 1240 rpm, belt drive, made in Taiwan. I've heard these are pretty good lathes and this one has only been used for rifle building in a one man shop. It's pretty dirty and full of chips, but seems real tight without much backlash. I'm going to take another look at it but what do you think of this model for gunsmithing?
