Leaving about 114 mm of the nails exposed, hammer two 150mm nails in opposite sides of the post, about 300mm 12in above ground level. Wind a long length of strong rope tightly round the post immediately beneath the nails. Stack bricks on each side of the post to a height just below that of the rope cushion’. Place a short but sturdy length of timber on top of the bricks and under the cushion and push down on it to lever the post upwards. Lever from each side of the post in turn and add a further brick, or bricks, as the post lifts.
