Spent time measuring, marking, and pilot drilling (to #40) holes in 8 SNX-W21-09 clips. These go on each end of the rib stiffeners, and tie-in to the aft wing skins. Were previously cut to length, and the other night I ripped to the correct width and deburred.
Rough day at work; this (Sonex) work, although menial and tedious, was beneficial to my mental health.
