fabricated the attach brackets for the right wing. deburred, countersunk (need some 426's) primed then riveted the assemblies.riveted the attach brackets to the wing assembly. buggered up 3 rivets (2 426-4's and one 470) doh!... drilled the 470 out to accept a -5 (cause I have some) and installed a 5 . works well.used a longer 426 for one hole and "pre" squished it, and fit,,, beautiful... nice to know I can fix my own screw ups more effectively now.
