Leading Edge and Inboard Skin

Got a few hours in and built up the Left wing leading edge. I've read other builders websites and knew that assembly within the constructed jig is very difficult. I opted to build on the table and work one cleco in at a time, one rib at a time.... it proved to be the best way. Trust me, I tried a few different methods.

I also had to trim the 5th. rib so it would fit over the larger Spar rivets. Now the Leading edge assembly fits nicely.
I cut and deburred the j-stringers for the Left wing and cleaned the edges of both the inboard skin and wing-walk doubler. Vans sent us the wrong size for one of those doublers but within a week i had the new one in my hand. Good service i say!

Right Wing Assembly

Tackled the right wing assembly on Wednesday and riveted all the main ribs to the forward spar. It didn't take too long with both Tad and I working on it. We left the rear spar and i finished that last night. So, the skeleton is together now for both wings!

Unfortunately the wing walk doublers which are .025 thickness skins and about 26" long are NOT the same length so i have a new one coming from Vans. One of them is 25 3/8" and the other is 26". 26" is the correct length. We can work on the leading edge ribs and skins and at least do the left wing walk doubler.

Tad is making the leading edge jig to make assembly much easier.
