Then remove the workpiece and change the pointed tip on the drive centre to the counterbore piece, and insert the drilled hole in the workpiece over the counterbore. Use the centring rod through the tailstock to centre the workpiece on the undrilled end while tightening up the tailstock. Then continue to drill through the remainder of the workpiece.
