Made 2 more spar jigs at the exact width of the spar caps (7-19/32").
Laid out the spar in the jigs and began drilling 3/32" pilot holes through the upper spar cap (!), using the already-drilled holes in the W10-01 spar web. Got 53 holes done. MANY more to go! And these are only pilot holes!
Spar laid out in 3 jigs
Wing tip end of spar
Long bit to avoid marring the spar cap. Used a triangle to keep it vertical to the spar web face.
