Our tech counselor Tom and my engineering buddy Eric joined me and Dad in the hangar today and we installed the wings on the fuselage for the first time. We used hardware store bolts to hold the wings on temporarily, then began the measurements and layout to set the wing sweep and incidence.
Once the wings were securely attached to the fuselage with the hardware store bolts, Tom and Eric went flying, while Dad and I checked and re-checked the measurements. Then we left things alone for the night.
A few days later, we went back out to the hangar to re-check the measurements again and drill the hole for the rear spar attach bolt. We used Van’s Wing Incidence Drilling Simplified checklist to make sure everything was copacetic before did any drilling.
We used the digital level taped to another carpenter’s level plus the recommended spacer block to help set the wing incidence. When the digital level read zero degrees, we knew the incidence was in the ballpark.
