This ingenious machine was made to counterbore two in line holes on a part at the same time and always be perfectly concentric with each other. Notice boring bar that is fed through the headstock to operate on back of part held in collet, while bar in tail stock does the work on the other side, Much jeweling work and jewel settings were made on this machine.
