Brief Description: Mark Aft Edge of Wing Tip Rib on Fiberglass Tip
On to the left wing tip...
First I installed the tip on the wing and then inserted the rib into the tip and slid it back far enough such that it fit snug without distorting the fiberglass tip. Then I marked the aft edges of the rib on the tip.
