I have used several lathes to thread and chamber barrels on. Acer 1340, Enco 12x36 belt drive, Leblond Regal 13 servoshift, Clausing Colchester 15, South Bend Heavy 10 just to name a few I've used in the past. Out of all these lathes the only one I have really felt like made the best Riflesmithing machine was and still is the South Bend Heavy 10!! Awesome machine it is!!!
