Tonight, I drilled all of the right wing main ribs to both spars. Not a lot of commentary, so I’ll just get to the pictures.
After drilling the middle two rear spar holes for each rib, I moved the clecos into those holes and matchdrilled the upper and lower holes.
Same with the front (although the clecos are in front of the main spar here).
Also, I have a question about some of the flange-to-flange holes. Here’s what I wrote on the forums:
I was working on drilling my main ribs to the main and rear spar last night, and the instructions say “drill all of the rib to spar attach holes.”
Then, they have you take everything apart, deburr, prime, and then rivet the ribs to the spars.
What should I do for the flange to flange holes? (Circled in green below, but there is one more on the ribs for the lower rear spar flange).
If I leave them as is now, I’ll be match-drilling them with the skins later, but then I won’t be able to deburr the holes (because the ribs are now riveted to the spars).
I could run a #40 bit through all of these holes and deburr before assembly. (I could also dimple the rear spar ones, since they will eventually be dimpled to accept the skin dimples.
Thanks in advance.
We’ll see what they say.
Then, I pulled off the rear spar.
(What a sad moment. I have had this clecoed together for a week or so, and every time I go in the garage, there’s a wing! How cool is that? Now, I’m back to rib deburring (or catching up on the left wing). Not as exciting as a wing skeleton.)
I can’t believe that took me an hour.
