Getting back into it is more difficult than I expected after this long period of inactivity.

I wanted to start countersinking or dimpling after having deburred most longerons on the forward fuselage but started hesitating on where to countersink and where to dimple and the more I was thinking about it, the more I started questioning myself. So decided not to start that and study the plans again before going any further.

One of the small easy tasks I did was drilling the two nutplate locations on the F-684 firewall gussets. These will hold the vent line later on in the process.

Also drilled  the nutplates on the F902-R and L bulkheads. again, attachment points for the vent line later on.
