Hello everyone.
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.
Any thoughts?
Thanks in advance.
