Drilled Holes for Wiring Conduit
Today I cut the holes for the wiring conduit runs. Basically, I drilled a #30 pilot hole in one rib, transferred that pilot hole and the tooling holes to a plywood template and then transferred the pilot hole to all the other ribs. It's kind of interesting because some of the ribs are 'left' ribs and some of the ribs are 'right' ribs. This doesn't denote which wing they're for but instead indicates the direction of the flanges (yes, some point left and some point right in a seemingly random order, but I'm sure there's a specific reason for this).
That's basically all I got done today because my sister-in-law who just moved back down South from Boston came over and we all went down to Stone Mountain and walked up the side of the thing...a very tiring experience to say the least. Stone Mountain is a very interesting geological formation basically because there are really no other mountains near Atlanta. This thing is solid granite and even causes 10 degrees of magnetic disturbance.
