thanx for the encouragement every one . I decided on a different approach than stacking the barrel plates together with the carrier block and pre drilling them like the plans call for , even a sharp drill will walk to some degree . I have a 10\" vert/horz rotary table and a DRO on the Bridgeport and I made a fixture for the 3 parts so as long as I indicate each part in to the fixture holding location shouldn\'t be a problem . any way , here\'s some more pics of the lathe work as I got it done .
