Spent half the day pulling head off a Jabiru ST 1600 and removing and lapping the valves. Time not counted as was not spend on the building of the Lightning.
Spent 5 hours refitting the AOA bolts into the wings - really tricky, particularly the rear bolts that carry the seat belts. Noticed that the large area washers on the bolts were touching the webbing on the seatbelts so ground a flat on the washers to make sure the webbing was not being touched.
