I am lucky enough to have a big green monster in my workshop, I have noticed if I put a lot of pressure on via the tail stock I can slow / stall the motor, the thrust bearings are adjusted as per the instructions, this does not occur with faceplate turning, and I have found I need to back off the tail stock quill to let the lathe get up to speed. No problem drilling with the tail stock it only shows when I hold stock with the tail stock live centers. It may have always been like this but I have never noticed it before, anyone else with a VB able to say if this is usual.
