Good productive Saturday in the shop.
Finished fitting the upper root skin to the wing. As this is the second one of these I have to do, I knew what it should look like when it was done and the easiest way to get there.
The root skin it attached at the rear channel first. I used some tape to hold it down at the main spar so I could scribe a line where the tank rib doubler strip and root rib lines are:
Working from the rear channel forward., A3 holes/clecos following the scribed lines:
A3 the up-sized to A4. The reflection of the shop lights make this skin look crinkled, but it curved out really smooth and I'm very happy with how it looks:
Next was pilot drilling the root skin doubler as it extends over the first nose rib. I wish the root skin doubler on my right wing turned out this nice, but that's the value of experience.
Disassembled the rear channel for debur and prime:
Once the primer was dry, I reassembled the rear channel and attached it to the wing. Measuring everything up to ensure the wing remains square is an important step:
On the right wing, I did the bulk of the riveting of the rear channel off of the wing skeleton. This time I decided it would be better to do it all on the wing in position - this too was a better way to do it.
The centre section where the two rear channels meet is also where the rear strut pick-up is located. I didn't rivet here yet because I want to fit the lower skins and trailing edges first.
Another good Saturday done, 7 hours total added to the tally board.
Next up, nose rib debur, prime and rivet - then the wing can be flipped over to work on the lower skins.
Thanks for following along, more to come.
