Tonight I started planning how to drill the extended fuel tank attach screw holes. The inboard ones were match drilled from the stock skin. My plan is to back drill from the spar through the skin. So I cleco’d on the wing ribs to the right wing and then cleco’d on the top skins. I pulled the wing out of the stand and placed it on some tables. I’ve laid the new skin onto the top of the spar and pushed it up against the top skins. I need to get a long drill bit to drill up from underneath. (I was planning on a right angle drill attachment but I think I can drill straight up from the bottom by putting the bit through the holes in the bottom flange. I just need a long #19 drill bit.


Once I get them drilled I’ll be ready to bend the skins at which point I get to start actually working on assmbling the fuel tanks. So far I’ve added 21.5 extra hours to the process prepping the new skins.

Time: 2 hours
