Found that the1.5" scotchbtite wheel that came in my tool kit worked well in an air die grinder and worked real well on all the edges and lightning holes. I finished all Left side ribs with edge deburring. Next I will drill conduit holes in the webs and I still need to flute and straightrn the flanges. After all this work i will still have the Right side to do as well as the nose and tank ribs for both sides. Boring stuff.
