I have set up a EQ6 pier in the back yard about 18 days ago, 150mm steel tube set in 400mm x400mm x0.9 mtr deep concrete block, then pipe filled with cement...... took 17 bags cement all up. machined up the seating and leveled to a split hair, all while the nights were perfect. then the night I went to set up for aligning the clouds/rain/hail started and has been that way ever since....grrr.
