Marathon back-busting sanding of large flat areas from last FILL.
Assessed result in the vicinity of the NACA, and find I still need considerable correction to progress from the plans offering to something within 10% of the profile of a proper NACA duct. Remark the centerline and the stations and make some templates for the reduced depth required in the first 4 stations.
Got a bit more aggresive with the sanding in the aft part of the duct which is already at a nice profile.
Hot glue in some dams to hold additional micro to the desire profile.
