Zenith CH750 STOL Build Log - Mounting the Wings!!! Part 2

I started to attach the lower strut fittings to the wings. The Drill press was very much a required piece of equipment for this task.

Since you leveled the strut length wise I am guessing you checked to make sure that being level it was also 90 deg, to the drill at the same time.

Correct, by using the drill press I am guaranteed a 90 degree angle to its base when I drill without having to measure. I verified that the base was level to the ground and finally checked that the strut was level left to right. The twist of the strut could not be measured externally as the entire outside of the strut is rounded. There are two flats inside the strut which is why I used the attachment brackets to align the strut with the clamps.
