the measurements are fine
A few important lessons learned here before drilling were priceless.
Measure twice, cut once. check, double check.
Be precise when trimming the rear spars.
replace the rivet above the rear spar with a flush rivet.
Clearly mark edge distance allowance on spar.
set incidence and clamp
drill to #30 and cleco, recheck incidence, and check edge distance
drill undersize and ream to final size
I must have looked at 15 builder's write-ups before drilling, then called vans and looked at more.
then drilled to final size.
It would seem that the biggest source of edge distance woes come from spar cutting errors.
