Wow. A 2 year delay is over. Back at it again. Re-measured incidence on left wing. The slight twist averaged 0.2 degrees up(positive). Vans had previously written and said I will always be trimming for passenger, fuel, etc,so either set root to zero and trim, or average the incidence and trim a little less. (I paraphrased their response). So, I chose average and then set the right wing to same 0.2 degrees up and rechecked for zero sweep both sides. Fuselage was level on both axis' so I did it. Had to switch to narrow air drill for final reaming. Left wing had plenty of safety margin to start hole. Right wing had a narrower 5/8" safety margin so I was careful to start a #40 hole precisely. All worked out fine and my temporary 5/16 Lowes bolts hold position until my NAS6205 close tolerance AN5-7's arrive. Wing twist measurement math: 105 inches long. Add negative or positive twist at change points. Multiply that times the # of inches to next significant change. Record as postive or negative number. Sum all numbers and divide by105 to get average twist. Set wing incidence at 0 plus(or minus) that number. Match right wing to that same number. 1. Fuselage to 13" = -0.1 degree 2. 17" @ 0.0 degrees 3. 10" @ +0.2 degrees 4. 10" @ +0.3 degrees 5. 10" @ +0.4 degrees 6. 10" @ +0.6 degrees 7. 22" @ +0.5 degrees. So, math is +247 divided by 105 = +0.2 degrees. Both wings set to +0.2 degrees.
Oak drill guide squared the hole nicely
Right wing incidence set to positive 0.2 degrees matching average of left wing.
