More Vertical Stab action thisarvo. got the Leading edge skin aft edges formed so they sit down nice, made some adjustments to the ABS tip and match drilled it. installed all the missing rivets in the fwd and aft spars, match drilled the fwd spar to the skins. I once again used the pen line on the flange for the center before drilling to see that there was enough meat left for the rivet. I then deburred all the holes and riveted on the left and right skins. Leading edge skin is riveted to the ribs and some rivets in the fwd spar. re checked for any twist and very happy there is none. only the rest of the fwd spar rivets and the tip to attach to finish.
