Finished all the matc drilling on both leading edge, It's a little anticlimatic, but now I take everything apart after identifying location of all the ribs. took off the top skins, leading edge and tanks. Deburred all the holes of the aft spars whils still in the jig, man this is going to be lots of deburring....broke the blade on the burraway, good thing I ordered a replacement at same time than I bought the tool.I can see that I'm starting a pile of repetitious work....
