The wing construction begins with countersinking for platenuts on the main wing spar. I needed to order the countersink tool for a #6 Screw to continue. I also ordered ones for #8 and #10. Waiting on Aircraft Tools Supply. In the meantime, I've started deburring the lightening holes and flanges for the many wing and tank ribs. May as well get that out of the way as it is quite tedious.
