Well finished the pier mount for EQ5 head and bolted it on the scaff pole which is in a foot square of concreate......looks good .....but the vibration on top end is terrible!!! i even pored postcreat down the scaff pole to numb it out a bit. plan is a 2 - 3 inch pipe over the scaff pole and more concrete in.
Right ordered the 150mm flue liner pipe off e-bay £18 for 9 ft!! got it the next day!! very good service. i have chiseled 20 mm or so out for the pipe to slipe over scaff pole and concreated it a quarter of a way up, going to wait for that to set, then sink the box pier in to pipe set in concreate/ or post create quick set, thats the plan.
