This is the final video on the vertical head repairs. It seems that the gear calculations in the previous video have resulted in the correct gear mesh. It takes three attempts to get the head reassembled with minor adjustment to the oil spinner required and the need to make a pin spanner to get sufficient torque on the nut which clams the spindle assembly.
